Live EVM on-chain data for Superposition (chain id 55244) — an Arbitrum-Orbit DeFi Layer-3 with ETH gas and on-chain yield-bearing Super Assets — served directly from the public Superposition JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the ETH balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole ETH with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and DeFi analytics across the Superposition and Arbitrum-Orbit ecosystem. Live keyless upstream. 5 endpoints.

Live EVM token-safety checks — does this token let you sell, and what will it cost you? A "honeypot" is a token you can buy but cannot sell: the contract blocks the sell, traps your money or charges a punishing tax. This API detects it the only reliable way — by actually simulating a buy and a sell of the token against its real liquidity pool on-chain, right now (powered by honeypot.is), and reporting whether the sell went through, the live buy/sell/transfer tax, the gas cost and a plain risk summary. Beyond the honeypot verdict it returns the token's DEX trading pairs with their on-chain reserves and USD liquidity, the largest holders with the top-10 supply concentration (a top-heavy token can be dumped on you), and whether the contract source is verified/open and makes proxy calls. Covers Ethereum, BNB Chain, Base and other EVM chains. This is the EVM token-safety cut via live buy/sell simulation — distinct from the Solana rug-risk feed, which inspects SPL mint authorities on a different chain with a different method. A safety signal, not financial advice — always verify before trading.

The major Ethereum liquid-restaking tokens (LRTs) compared side by side, read keyless directly from the Ethereum blockchain via a public RPC node. Restaking is the DeFi narrative EigenLayer kicked off: you stake ETH and then restake it to also secure other services, earning Ethereum staking rewards PLUS restaking rewards on top. A liquid-restaking token — weETH (ether.fi), ezETH (Renzo), pufETH (Puffer) or rswETH (Swell) — is the liquid receipt for that position, and its on-chain exchange rate against ETH climbs as those combined rewards accrue. Restaking is a distinct, fast-moving asset class from plain liquid staking, and the spread between these tokens' rates and yields is what someone choosing a restaking provider (or arbitraging between LRTs) needs in one place. The rates endpoint is the comparison table: every tracked LRT with its live ETH exchange rate, its net APR over the last 30 days, its token supply and its issuer, ranked by yield. The token endpoint drills into one LRT by symbol — its rate, supply, ETH backing (TVL) and the APR over the last day, week and month. The convert endpoint converts any amount between any LRT and ETH, or between two LRTs, at the current on-chain rates. This is the liquid-RESTAKING comparison cut — distinct from liquid-STAKING tokens (the lstcompare feed), the single-protocol feeds (ether.fi, lido) and the DeFi-TVL feeds. Each token rate comes from its own on-chain rate source (a getRate() call, a rate-provider, or an ERC-4626 vault, depending on the protocol). APR is derived from real historical on-chain state; the 30-day window is used because several LRT rates update on an oracle schedule or in discrete ERC-4626 steps, making shorter windows noisy. The rate reflects realised value accrual — many LRTs additionally distribute points/airdrops that are NOT captured by the exchange rate. Rates are ETH per token. Keyless, nothing stored beyond a short cache.

The major Ethereum liquid-staking tokens (LSTs) compared side by side, read keyless directly from the Ethereum blockchain via a public RPC node. When you stake ETH through Lido, Rocket Pool, Coinbase, Binance or Frax you receive a liquid-staking token — wstETH, rETH, cbETH, wBETH or sfrxETH — whose on-chain exchange rate against ETH climbs as staking rewards accrue. Those rates, and the yields implied by how fast they climb, differ between providers, and that spread is exactly what someone choosing where to stake (or arbitraging between LSTs) needs in one place. The rates endpoint is the comparison table: every tracked LST with its live ETH exchange rate, its net staking APR over the last week (derived from the on-chain rate growth), its token supply and its issuer, ranked by yield. The token endpoint drills into one LST by symbol — its rate, supply, ETH backing (TVL) and the APR over the last day, week and month. The convert endpoint converts any amount between any LST and ETH, or between two LSTs, at the current on-chain rates. This is the cross-LST comparison cut — distinct from the single-protocol feeds (lido, Rocket Pool, ether.fi) and the DeFi-TVL feeds: it is about the exchange rates and on-chain-derived yields of the staking tokens themselves. Every number is read live from each token contract; APR is derived from real historical on-chain state, not a marketing figure. Rates are ETH per token. Keyless, nothing stored beyond a short cache.

api.oanor.com/lstcompare-api

Live data for Lido, the largest liquid-staking protocol in crypto, read keyless directly from the Ethereum blockchain via a public RPC node. Stake ETH with Lido and you get stETH, a rebasing token worth one ETH that earns Ethereum staking rewards; wstETH is the wrapped, non-rebasing version whose exchange rate against stETH grinds upward as rewards accrue — the form most of DeFi actually holds. Lido is by far the biggest staker of ETH, so its size and yield are a benchmark the whole staking market is measured against. The overview endpoint is the headline: how much ETH is staked through Lido (its TVL in ETH, equal to the stETH supply), the wstETH supply, the current wstETH-to-stETH exchange rate and the net staking APR. The apr endpoint computes the real, net-of-fees staking yield directly from the on-chain wstETH exchange rate — how much that rate has grown over the last day, week and month, annualised with actual block timestamps — the honest yield a wstETH holder has earned, not a marketing figure. The wsteth endpoint is the wstETH conversion reference: how much stETH one wstETH is worth and vice-versa, the wstETH supply and the share of stETH that is wrapped. The convert endpoint converts any amount between ETH, stETH and wstETH at the current on-chain rate. This is the Lido cut — distinct from ether.fi (liquid restaking), Rocket Pool (rETH) and the Ethereum staking-queue and consensus feeds. Everything is read live from the stETH and wstETH contracts; no USD value is fabricated. Keyless, nothing stored beyond a short cache.

The live Ethereum validator entry and exit queues, read keyless straight from a public consensus-layer (Beacon) node. To stake on Ethereum you join a queue to activate a validator, and to unstake you join a separate queue to exit — both rate-limited by the protocol churn limit. The size of these queues is the cleanest real-time signal of staking demand and exit pressure: a long entry queue means capital is rushing in to stake, a long exit queue means validators are leaving. Liquid-staking protocols, exchanges, stakers and ETH analysts watch the queue to time deposits and withdrawals. The queue endpoint is the headline dashboard — how much ETH is waiting to activate (entry) versus exit, the validator counts behind each, the net flow, and an estimate of how long each queue takes to clear at the current activation/exit churn limit (256 ETH per epoch, ~6.4 min). The entry endpoint breaks down the activation side (validators already eligible and churning in, plus freshly-deposited validators not yet eligible). The exit endpoint breaks down the exit side (voluntary exits plus validators forced out by slashing). The validator endpoint looks up any single validator by index or public key: status, balance, effective balance, slashed flag and activation/exit epochs with wall-clock times. ETH amounts are the meaningful queue metric — a single post-Pectra validator can hold up to 2048 ETH — with counts given alongside. Distinct from beaconchain-api (consensus finality), the Solana validator feeds and the liquid-staking protocol feeds. Live, keyless, nothing stored beyond a short cache.

Live data for ether.fi, the largest liquid-restaking protocol on Ethereum, read keyless from ether.fi's public APR feed and directly from the Ethereum blockchain. Stake ETH with ether.fi and you get eETH, a rebasing token worth one ETH that earns both Ethereum staking rewards and EigenLayer restaking rewards on top — the "restaking premium" that made liquid restaking the fastest-growing corner of DeFi. weETH is the wrapped, value-accruing version of eETH that most of DeFi actually holds and lends against, and its eETH exchange rate is the number you need to value it. The apr endpoint returns the eETH restaking APR — the latest reading plus the recent daily history and its average. The restaked endpoint reads the chain directly: the total ETH restaked through ether.fi (the eETH supply, which rebases to track ETH one-for-one) and its US-dollar value, plus how much of it is wrapped into weETH versus held as eETH. The weeth endpoint is the wrapped-token view: the weETH supply and its on-chain rate — how much eETH (and therefore ETH and USD) one weETH is worth right now, the figure lending markets use to price weETH collateral. This is the ether.fi liquid-restaking cut — distinct from the synthetic-dollar protocol feed, the generic staking and yield-aggregator feeds and the generic token-info feed: it is the single-protocol view of the biggest restaking token, its yield, its size and its wrapped-token rate. APR is an annualised percentage; amounts are in ETH and USD; the rate is eETH per weETH (above 1.0, rising as yield accrues). No key, nothing stored beyond a short cache.

The on-chain prices that DeFi actually runs on, read live and keyless straight from Chainlink's price-feed contracts on Ethereum. Chainlink is the dominant oracle: a decentralised network writes each price on-chain and refreshes it on a heartbeat or when it moves past a deviation threshold, and thousands of lending, perpetual and stablecoin protocols read that exact number to value collateral and trigger liquidations. What matters is not just the price but whether the feed is fresh — a stale Chainlink feed is how DeFi protocols break — and that on-chain freshness is exactly what this exposes. The feeds endpoint lists every tracked Chainlink feed (crypto, stablecoins and FX) with its current on-chain answer, how many seconds ago it last updated and whether it is fresh. The feed endpoint returns one pair's full detail by name, including the round id, the update timestamp and the feed contract address. The health endpoint is the oracle-monitoring view: how many feeds are fresh versus stale, the stalest feed and the average update age — the on-chain reliability picture that a plain price API can't give you. Each price is read from the feed's latestRoundData and scaled by the feed's own on-chain decimals (USD feeds use 8); the update time is the contract's updatedAt. This is the Chainlink on-chain-oracle cut — distinct from the off-chain oracle-price APIs (which serve a price but not the on-chain feed's round and freshness) and from the exchange price feeds. Prices are in the feed's quote unit (USD here); times are UTC. No key, nothing stored beyond a short cache.

How much Bitcoin lives on Ethereum, and through whose vault, read live and keyless straight from the Ethereum blockchain. Bitcoin itself can't run in DeFi, so it gets "wrapped": a custodian (or a decentralised bridge) locks real BTC and mints a 1:1 ERC-20 that trades on Ethereum. WBTC (BitGo) was the original and long the only one that mattered, but after the 2024 custody controversy a competitive market opened up — Coinbase's cbBTC, the decentralised tBTC (Threshold), Lombard's LBTC, Kraken's kBTC and others now split the pie. The wrappers endpoint lists every tracked wrapped-Bitcoin token ranked by the BTC it holds, each with its issuer/custodian, the BTC backing it, its US-dollar value and its share of all wrapped BTC, plus the totals. The token endpoint returns one wrapper's detail by symbol. The dominance endpoint is the concentration view — WBTC's share, the split between custodial wrappers (a company holds the BTC) and the decentralised one, and how concentrated the market is — the counterparty-risk picture for Bitcoin in DeFi. Each token's BTC backing is read as its on-chain total supply divided by its own decimals (read live from the contract — they are not all 18: WBTC and cbBTC use 8, tBTC uses 18), which equals the BTC held because every wrapper is minted 1:1 against locked Bitcoin. This is the wrapped-BTC / BTC-on-Ethereum cut — distinct from the coin price feeds, the generic ERC-20 token-info feed and the stablecoin feeds. Supplies are in BTC; values in USD (BTC priced from Yahoo Finance). No key, nothing stored beyond a short cache.

Live data for Ethena's USDe, the largest synthetic dollar in crypto, read keyless from Ethena's public yield feed and directly from the Ethereum blockchain. USDe is not backed by fiat in a bank like USDC — it is a delta-neutral synthetic dollar: Ethena holds staked ETH/BTC and shorts the matching perpetual futures, so the position is hedged to roughly one dollar while the funding and staking it earns become the yield. Stake USDe into sUSDe and you receive that yield; sUSDe is the yield-bearing version and its value in USDe grows every day. The yield endpoint returns Ethena's yields — the current protocol yield and sUSDe staking yield plus the 30-day, 90-day and since-inception average sUSDe APY — the carry the synthetic dollar throws off, which rises and falls with the perpetual-futures funding market. The supply endpoint reads the Ethereum contracts directly: the circulating USDe supply, the amount of USDe staked in sUSDe, the sUSDe share count, the sUSDe-to-USDe exchange rate (how much USDe one sUSDe is now worth — above 1.0 because yield has accrued) and the staking ratio (what share of USDe is staked and earning). The overview endpoint is the at-a-glance snapshot combining the supply and the live yield. This is the Ethena / USDe synthetic-dollar cut — distinct from the generic multi-stablecoin supply feeds, the DeFi lending-rate and yield-aggregator feeds, and the generic ERC-20 token-info feed: the single-protocol view of how the synthetic dollar is sized, staked and yielding. Yields are annualised percentages; supplies are in USDe; the exchange rate is USDe per sUSDe. No key, nothing stored beyond a short cache.

The Solana MEV (maximal extractable value) layer via Jito, live and keyless. On Solana, Jito runs the dominant block-engine: searchers bundle transactions and attach a tip to land them, validators running the Jito client capture that MEV, and a slice flows to JitoSOL stakers. This API exposes the two numbers that matter to anyone building or trading on Solana. The tip-floor endpoint returns the live MEV tip floor — the landed-tip amount at the 25th, 50th, 75th, 95th and 99th percentile (in SOL and lamports) plus the smoothed (EMA) median: the real-time price of priority that every Solana trading bot reads before sending a bundle. The rewards endpoint returns the daily MEV economy — for each recent day the number of MEV tips, how many distinct tippers paid, and the total SOL tipped to validators and to Jito: a read on how much MEV Solana is generating. The validators endpoint ranks the Jito-running validators by stake, each with its MEV commission, priority-fee commission, Jito-directed stake and current-epoch MEV rewards — the MEV configuration of Solana's validator set. This is the Solana MEV / Jito cut — distinct from the Ethereum MEV-Boost builder-and-relay feed (a different chain and mechanism: Solana uses a tip auction, not a builder market), from the Solana validator-decentralisation feed (stake distribution, not MEV) and from the Solana network-performance feed. Tips and rewards are in SOL (tips also in lamports); stake is in SOL; commissions in percent. Sourced live from Jito's public APIs, keyless.

The best liquidity-pool, staking and vault yields across DeFi, with the risk profile that decides whether a headline APY is actually worth farming — live from DeFiLlama, no key. A pool can advertise 40% APY, but if it is a volatile two-token liquidity position the impermanent loss can eat the yield, and if the rate spiked yesterday it may be gone tomorrow. This API is the yield-farming screener: for every non-lending pool (DEX liquidity, staking, vaults, farms) it returns the current APY split into base and reward, the 30-day average APY, a sustained APY (the lower of the two, so a pool only scores high if it yields well both now and on average), the impermanent-loss risk and exposure (single-asset or multi-token), whether it is a stablecoin pool, the TVL and daily trading volume, and DeFiLlama's own forward prediction of whether the APY will hold, rise or fall. The pools endpoint is the full screener, filterable by project, chain, asset, stablecoin-only, exposure, IL-risk and minimum size, sorted by current or 30-day or sustained APY, TVL or volume. The best endpoint answers the question directly — the highest-yielding farms ranked by the sustained APY so the answer is real and farmable, not a one-day spike; add stablecoin=true or exposure=single for lower-risk yield. The project endpoint summarises one protocol's pools (Uniswap, Curve, Pendle, Convex). The LP / staking / vault yield-farming cut — distinct from the on-chain money-market lending-rate API (supply and borrow rates, which this one excludes entirely), from the TVL analytics APIs, and from price feeds. Ranking surfaces exclude DeFiLlama-flagged outlier pools so the best yield is one you could actually farm.

When locked crypto tokens vest into circulation, who they go to, and how much supply is still to come — live from DeFiLlama's open emissions dataset, no key. A token's price tells you what it costs today; its unlock schedule tells you the supply pressure ahead, the single biggest and most predictable overhang in crypto. When a large tranche of insider, private-sale or team tokens vests, it is fresh sell-side supply hitting a fixed amount of demand — and these dates are known in advance. A static "percent unlocked" number (which dilution APIs give) is only a snapshot; what a trader needs is the calendar: when is the next cliff, how many tokens, what share of total supply, and to whom. The protocols endpoint lists every token DeFiLlama tracks a schedule for (searchable). The next endpoint is the trading signal — the next upcoming cliff unlock for a token: its date, days away, token amount, the share of total supply it dilutes, the unlock type and the recipients (insiders, private sale, team, ecosystem), plus the unlocks after it. The schedule endpoint returns the fuller picture: total and max supply, the allocation by category with how much of each is already unlocked, the count of past and future events, the tokens still locked, and the upcoming events. The token-unlock / vesting-schedule cut — distinct from the tokenomics-and-dilution APIs (which give the static supply and FDV snapshot, not the dated unlock calendar) and from price and market-cap APIs. Amounts are in tokens and as a share of total supply; pair with any price API for the dollar value.

The supply and borrow rates of on-chain money markets, compared across every major DeFi lending protocol and chain at once — live from DeFiLlama, no key. The same asset earns and costs a different rate on every protocol and every chain: USDC might pay 3% to supply on Aave v3 Ethereum and cost a fraction to borrow somewhere else, and those rates move every block. A single protocol's reserves are only part of the picture; what a lender or borrower wants is the cross-protocol, cross-chain comparison. This API joins DeFiLlama's pool yields with its lend/borrow dataset into one money-market table: for every lending reserve it gives the supply APY (base + reward), the borrow APY (base + reward), the utilisation, the loan-to-value and the dollar size of the supplied and borrowed pools. The markets endpoint returns the full table (filter by asset, chain, protocol, stablecoin, minimum size); the best endpoint returns the top venues to supply an asset (highest APY) or to borrow it (lowest APY) right now; the asset endpoint summarises one asset across all its markets — the min, max, average and median supply and borrow APY, plus the single best place to lend and to borrow. Ranking surfaces exclude DeFiLlama-flagged outlier pools and impossible (>100%) utilisation, so the best rate is a real, harvestable one. The cross-protocol money-market-rates cut — distinct from TVL analytics (which size protocols, not their rates), single-protocol lending APIs (one venue each), and perpetual funding-rate APIs (a different rate entirely).

Live on-chain options and perpetuals data from Aevo, a leading decentralized derivatives exchange — no key, nothing stored. This is the on-chain options view: the full option chain with strikes, expiries, mark prices, implied volatility and the option greeks, plus live perpetual stats, distinct from the Deribit-based and other derivatives APIs in the catalogue — Aevo is an on-chain options and perps venue. The options endpoint returns the option chain for an asset — calls and puts by strike and expiry, each with mark and index price, implied volatility and the greeks (delta, gamma, theta, vega, rho). The stats endpoint returns the live perpetual statistics for an asset: open interest, index and mark price, the 24h change, funding and 24h volume.

Live lending-market data from Solend (now Save), the leading Solana money market, over its public API — no key, nothing stored. This is the Solana lending view: every asset in the main pool with its supply and borrow APY, utilisation, value supplied and value borrowed, distinct from the other DeFi, DEX and lending APIs in the catalogue — Solend is an on-chain money market on Solana. The markets endpoint lists every asset with its live rates, utilisation and TVL, ranked by value supplied. The asset endpoint returns one asset by its symbol — its supply and borrow APY, utilisation, oracle price and the dollar value supplied and borrowed. The summary endpoint aggregates the pool: total value supplied and borrowed, asset count, the overall utilisation and the largest markets. Build DeFi lending dashboards, yield comparators, borrow-rate monitors and risk tools on top of real Solend data. Rates are live supply/borrow APYs and USD values are derived from on-chain reserve amounts and oracle prices; look up an asset by symbol (SOL, USDC).

Live concentrated-liquidity DEX data from Orca, the leading Solana CLMM exchange, over its public Whirlpools API — no key, nothing stored. This is the Solana on-chain liquidity view: every Whirlpool with its value locked, trading volume, price and the yield earned by liquidity providers, distinct from the aggregator, AMM and other DeFi APIs in the catalogue — Orca is concentrated-liquidity (Uniswap-V3-style) on Solana. The pools endpoint lists Whirlpools, optionally filtered by token and ranked by value locked or 24h volume, each with its pair, price, fee tier, volume and APR. The pool endpoint returns one Whirlpool in full by its on-chain address — including 7-day and 30-day volume, weekly and monthly APR, the fee APR, tick spacing and token mints.

Live protocol stats from Sky, the decentralized stablecoin protocol formerly known as MakerDAO and the issuer of the USDS and DAI stablecoins — no key, nothing stored. This is the Sky-protocol view: the Sky Savings Rate (SSR) and DAI Savings Rate (DSR), the value locked in savings, the SKY staking yield and the overall ecosystem size, distinct from the generic DeFi-TVL, yields and lending APIs in the catalogue. The overview endpoint returns the latest ecosystem snapshot — the Sky Savings Rate APY, the savings TVL, the SKY staking APY, the farm APY, the total reward TVL, the whole-ecosystem TVL, the wallet count and the number of savings depositors. The savings endpoint returns the current savings rates: the live SSR and DSR and the dollar value deposited in each. The history endpoint returns the savings-rate timeline — per-day SSR, DSR and deposited totals — so you can chart how the on-chain risk-free rate has moved. Build DeFi yield dashboards, stablecoin-savings widgets, rate-comparison tools and treasury bots on top of the dominant decentralized stablecoin protocol. SSR and DSR are the on-chain savings benchmarks for USDS and DAI; rates are returned as percentages.

Live Ethereum layer-2 / rollup risk and value-secured data from L2BEAT — no key, nothing stored. L2BEAT's signature is its independent risk framework: every rollup is rated by maturity Stage (Stage 0 / 1 / 2) and assessed across the canonical risk dimensions — sequencer failure, state validation, data availability, exit window and proposer failure — each carrying a good / warning / bad sentiment and a plain-language explanation. This is the rollup-risk and total-value-secured (TVS) view, distinct from the L2 economics/fundamentals and the on-chain per-chain APIs in the catalogue. The projects endpoint lists every tracked L2 with its type (Optimistic Rollup, ZK Rollup, Validium, layer3…), category, host chain, maturity Stage, TVS and 7-day change. The project endpoint returns one rollup in full — the TVS breakdown (native / canonical / external, and ether / stablecoin / btc / other), the Stage, providers, purposes and the complete risk assessment. The risks endpoint returns just the risk rosette for a rollup with a sentiment tally. The summary endpoint aggregates the whole ecosystem — total TVS, project count and the distribution by Stage and by type. More than a hundred rollups tracked, updated live. Project lookup is by slug (arbitrum, base, optimism, zksync-era, scroll, linea, starknet).

Live audit of the token approvals (allowances) a crypto wallet has granted, and the risk of the contracts it has approved to spend its tokens — powered by the public GoPlus Security data, no key, nothing stored. Token approvals are the single most common way wallets get drained: once you approve a contract to move a token, a malicious or compromised spender can take it whenever it likes. This is the allowance-hygiene layer — the data behind tools like revoke.cash. The approvals endpoint lists every token a wallet has approved, who it approved (the spender contract), how much was approved and when, and whether that spender is flagged as malicious, trusted or unverified, together with a risk summary counting the dangerous approvals to revoke. The contract endpoint profiles a single spender contract before you approve it — its name, whether it is open-source, its creator, deploy time and risk tags. The chains endpoint lists the 40-plus supported blockchains. Catch wallet-draining allowances before they cost a user everything. This is the approval / allowance-risk cut — distinct from the token-contract-security, scam-detection and on-chain APIs in the catalogue.

Live on-chain crypto options trading volume — the decentralized options market where protocols like Derive, Aevo, Premia, Ithaca and Rysk let users trade calls and puts on-chain, powered by the public DeFiLlama options feed, no key, nothing stored. This is distinct from a centralized options exchange order book: it measures the volume actually flowing through on-chain options venues. The overview endpoint returns the whole on-chain options market's volume over the last 24 hours, 7 days and 30 days plus every protocol ranked by what it trades, measured as notional (contract face value, the default) or premium (what option buyers actually paid). The protocol endpoint returns a single protocol's notional and premium volume side by side across 24h / 7d / 30d / all-time. The chain endpoint returns the options volume and top venues for one blockchain. See which on-chain options venue leads and how DeFi options flow shifts. This is the on-chain options-volume cut of DeFi — distinct from the centralized options-chain, spot-DEX, swap-aggregator, fees and perpetual APIs in the catalogue.

Live smart-contract risk and safety analysis for crypto tokens and wallet addresses — the on-chain due-diligence check to run before you buy a token or interact with an address, powered by the public GoPlus Security data, no key, nothing stored. The token endpoint scans an ERC-20-style contract on any supported chain and returns whether it is a honeypot, its buy and sell tax, whether it is mintable or has a hidden or privileged owner who can pause trading or take back ownership, whether it is open-source or a proxy, and its holder and LP-holder counts. The address endpoint screens a wallet address against twenty risk signals — cybercrime, money laundering, phishing, sanctions, stealing attacks, honeypot-related addresses and more — and reports exactly which, if any, are flagged. The chains endpoint lists the 40+ supported blockchains. Catch scam tokens, honeypots and tainted addresses before they cost you. This is the real-time contract-security and risk-screening cut of crypto — distinct from the historical exploit database, the price and the on-chain APIs in the catalogue.

Live trading volume routed through DeFi DEX aggregators — Jupiter, 1inch, CowSwap, Paraswap, OKX Swap, KyberSwap and more — powered by the public DeFiLlama aggregators feed, no key, nothing stored. Aggregators don't hold liquidity themselves: they split each trade across many underlying decentralized exchanges to get the best price, so their volume is the single best measure of where real swap flow actually routes. The overview endpoint returns total aggregator volume over the last 24 hours, 7 days and 30 days plus every aggregator ranked by what it routes, with its category and the chains it covers. The aggregator endpoint returns a single aggregator's volume across 24h / 7d / 30d / all-time. The chain endpoint returns aggregator volume and the top routers for one blockchain (Solana, Ethereum, Base). See which router dominates each chain and how swap flow shifts. This is the swap-routing / aggregator-volume cut of DeFi — distinct from the spot-DEX-volume, fees-and-revenue, TVL and exchange-ticker APIs in the catalogue.

Live aggregate data for the whole cryptocurrency market — the top-down view, not a single coin, exchange or trading pair, powered by the public CoinGecko global feed, no key, nothing stored. The overview endpoint returns the combined market capitalisation of all crypto, the total 24-hour trading volume, the market-wide 24-hour cap change, the number of active cryptocurrencies and markets, and the ongoing / upcoming / ended ICO counts. The dominance endpoint returns each leading coin's share of total market cap — Bitcoin dominance, Ether dominance, the stablecoin share and the long-tail rest — the single most-watched gauge of where money sits in crypto. The defi endpoint returns the decentralized-finance sub-market: its market cap, its share of total crypto, its 24-hour volume and the largest DeFi token. Track total market cap, BTC dominance and the DeFi share as live JSON. This is the whole-market aggregate cut — distinct from the single-coin, single-exchange and cross-exchange coin-markets APIs in the catalogue.

Live DAO governance data from Snapshot, the off-chain voting platform where most crypto DAOs run their proposals and votes — read from the public Snapshot GraphQL hub, no key, nothing stored. The proposals endpoint returns governance proposals newest-first, filterable by DAO space and state (active, closed, pending), each with its title, choices, total voting power, vote count and open/close timing. The proposal endpoint returns a single proposal in full: the body, every choice with its score, the author, the quorum and the timing. The votes endpoint returns the votes cast on a proposal, ranked by voting power, with each voter, their choice and their token-weighted weight. The space endpoint returns a DAO space's profile — follower, proposal and vote counts, network and governance token. Track what Aave, Uniswap, Arbitrum and thousands of other DAOs are voting on right now. This is the DAO-governance cut of crypto — distinct from the price, market, on-chain, DeFi and exchange APIs in the catalogue.

A live database of cryptocurrency and DeFi hacks, exploits and thefts — every major on-chain theft on record, powered by the public DeFiLlama hacks dataset, no key, nothing stored. Each incident carries the victim, the amount stolen in US dollars, the date, the attack technique (flash-loan oracle manipulation, reentrancy, private-key compromise, access-control exploit and more), a higher-level classification, the chain or chains involved, the target type (DeFi protocol, centralized exchange, bridge, wallet, token) and how much, if any, was later returned. The hacks endpoint returns the incident list newest-first, filterable by chain, technique, target type, classification, year and minimum loss. The biggest endpoint ranks the largest exploits of all time by dollars stolen — from the multi-billion-dollar bridge and exchange breaches down. The stats endpoint aggregates the whole dataset: total stolen, incident count, funds returned, and breakdowns by attack technique, chain, target type and year. This is the crypto-security and exploit-history cut — risk and post-mortem data distinct from the price, market, TVL, fees and on-chain APIs in the catalogue.

Live data on the fees users pay to DeFi protocols and the revenue those protocols actually keep — the "which protocols earn money" view, a different layer from Total Value Locked. TVL is what is deposited; fees are what users pay to use a protocol; revenue is the slice the protocol or its token-holders retain. Powered by the public DeFiLlama fees feed, no key, nothing stored. The overview endpoint returns the whole-DeFi fee (or revenue) total for the last 24 hours, 7 days and 30 days plus every protocol ranked by what it earns, with its category and chains. The protocol endpoint returns a single protocol's fee and revenue figures side by side across 24h / 7d / 30d / all-time (e.g. Aave, Uniswap, Lido). The chain endpoint returns the fee or revenue total and top-earning protocols for one blockchain (Ethereum, Solana, Base). Switch any list between gross fees and retained revenue with a single metric parameter. This is the fees-and-revenue cut of DeFi — distinct from the TVL, DEX-volume, exchange-ticker and coin-markets APIs in the catalogue.

Live crypto token prices by contract address — no key, nothing cached. Unlike price APIs keyed on a coin slug, this prices a token by its on-chain contract address on its chain, exactly what you have when a token comes out of a wallet, a DEX pair or a transaction. The price endpoint returns the current USD price, symbol, decimals, a confidence score and the timestamp for one or many tokens at once, addressed as chain:address (ethereum:0xA0b8…, a Solana mint, etc.) or as coingecko:slug — USD Coin resolves to about $1.00 and Wrapped Ether to its live price, in one batched call. The historical endpoint returns a token's price at any past moment by Unix timestamp. The chart endpoint returns a price series over a span and period, so you can plot or back-test. It spans every chain DefiLlama indexes — Ethereum, Solana, BSC, Base, Arbitrum and dozens more — including long-tail tokens a slug-based API will not have. This is the address-based price layer every wallet, portfolio tracker, DEX tool and crypto-accounting app needs to value arbitrary tokens. Live from DefiLlama, nothing stored. Distinct from coin-slug price and market-cap APIs — this prices tokens by contract address, across chains. 4 endpoints.

Live decentralised-exchange trading-pair data — no key, nothing cached. For any token or trading pair across every major chain and DEX (Ethereum, Solana, BSC, Base, Arbitrum, Polygon and dozens more, on Uniswap, Raydium, PancakeSwap and the rest) it returns the live on-DEX market: the price in USD and in the native quote token, the pool liquidity, the 24-hour volume, the fully-diluted valuation and market cap, the price change over 5 minutes, 1, 6 and 24 hours, and the count of buy and sell transactions. The search endpoint finds every pair matching a token symbol, name or address. The token endpoint returns all the pools a token trades in, ranked by liquidity, so you can find where the real liquidity is — Wrapped Ether trades in pools led by a Uniswap WETH/USDC pool with tens of millions in liquidity. The pair endpoint returns one specific pool by chain and pair address in full detail. This is the DEX market-data layer every trading, screener, wallet, sniping and portfolio app needs — real pools, real prices, every chain. Live from DexScreener, nothing stored. Distinct from aggregate DEX-volume and centralised-exchange ticker APIs — this is per-pair on-DEX data. 4 endpoints.

Live market data for crypto sectors and narratives — the themes the market actually trades, not single coins. Served from the public CoinGecko categories feed (no key, nothing cached), it ranks hundreds of sectors: Smart Contract Platforms, Layer 1s and Layer 2s, Memes, Artificial Intelligence, Real-World Assets, DePIN, Gaming, DeFi, Liquid Staking and many more. For each category it gives the total market capitalisation, the 24-hour market-cap change, the 24-hour trading volume and the three largest coins in that sector — so you can see, for example, that the Meme sector is roughly a $30B market led by Dogecoin and Shiba Inu, and which narratives are pumping or bleeding today. The categories endpoint ranks every sector and can be sorted by market cap, 24-hour change or volume; the category endpoint returns one sector by id or name with its market-cap rank and description; the movers endpoint surfaces the top gaining and losing narratives over the last 24 hours, filtered to real sectors so micro-cap dust does not distort the board. This is the sector-rotation and narrative-tracking layer for any crypto research, screener, portfolio or dashboard app — which themes hold the money and which are moving. Live from CoinGecko, nothing stored. Distinct from single-coin price, market-cap and mover APIs — this is the market by sector and narrative. 4 endpoints.

Live ERC-20 token metadata, read straight off the blockchain. Give it any token contract address and it returns the token's name, symbol, decimals and total supply — both as the raw on-chain integer and as a human-formatted number — by calling the ERC-20 contract directly via the chain's public JSON-RPC node (eth_call), confirming first that the address is really a contract. The USD Coin contract resolves to "USD Coin", symbol USDC, 6 decimals; Wrapped BTC on Polygon to "(PoS) Wrapped BTC", symbol WBTC, 8 decimals. The balance endpoint reads any wallet's holding of any token — pass the token contract and an owner address and it returns the balance raw and formatted with the token's own decimals and symbol. It works across seven EVM chains — Ethereum, Polygon, BNB Smart Chain, Arbitrum, Optimism, Base and Avalanche — with friendly aliases (eth, matic, bnb, arb, op, avax). This is the token-metadata and token-balance layer every wallet, DEX, portfolio tracker, block explorer and DeFi dashboard needs: turn a bare 0x… contract into a named, decimalled token, and resolve any holder's balance, in one call. Read live from the chain, no key on the data source, nothing cached. Distinct from native-coin balance and market-price APIs — this is on-chain ERC-20 contract data read directly from the blockchain. 4 endpoints across 7 chains.

Live DeFi yield-farming APYs across the whole decentralised-finance ecosystem as an API, streamed from the DefiLlama yields feed. For thousands of liquidity pools across every chain and protocol: the current APY split into base and reward, the pool's TVL, its chain, project and token symbol, whether it is a stablecoin pool and its impermanent-loss risk. Rank the top yields with a sensible TVL floor (so dust-pool noise is filtered out), drill into any single protocol or chain, filter to stablecoin pools, or search. Built for DeFi, yield-aggregator and dashboard apps. Distinct from TVL and price APIs — this is the live yield surface. Note: very high APYs are reward-driven and transient; use a TVL floor, the stablecoin filter, or sort by TVL for durable yields.

Decentralized-finance analytics as an API, powered by DeFiLlama — the most-used, independent dashboard for tracking Total Value Locked (TVL) across the DeFi ecosystem. TVL is the dollar value of assets deposited in a protocol, the key measure of a DeFi protocol's size and health. This API wraps DeFiLlama's open data into clean, compact JSON. /v1/protocols ranks DeFi protocols by TVL and lets you filter by blockchain (chain=Ethereum) and by category (category=Lending, Dexes, Liquid Staking, CDP, Yield, Bridge and more) — each protocol with its slug, token symbol, category, the chains it runs on, its TVL in USD and 1-day and 7-day TVL change. /v1/protocol?slug=aave returns a single protocol's profile and its current TVL broken down by blockchain (real chains only, so the headline figure is not inflated by staking or borrowed aggregates). /v1/chains ranks every blockchain by the TVL deployed on it. /v1/stablecoins ranks stablecoins by circulating supply, with each coin's peg type and peg mechanism. All values are in US dollars and reflect the latest snapshot. Ideal for crypto and DeFi dashboards, portfolio and risk tools, market-research and analytics products, and Discord/Telegram bots. This is on-chain/DeFi analytics — distinct from token-price feeds. Use a protocol slug from /v1/protocols for the detail endpoint. Data from DeFiLlama (free and open).
