Fetch verifiable Merkle-Patricia proofs of EVM account and storage state, live, via the chain's public JSON-RPC (eth_getProof, no key). For any address it returns the account's nonce, balance, code hash and storage hash together with the Merkle account proof; for any storage slot it returns the value and its storage proof; and it exposes the block's state, transactions and receipts roots — the roots those proofs verify against. This is the light-client and cross-chain-verification primitive: prove that an account existed or that a storage value was exactly what you claim at a given block, without trusting an indexer. Used by bridges, rollup verifiers, light clients and audit tooling, across Ethereum, Base, Arbitrum, Optimism, BNB, Polygon and more. Reads straight from the chain; live, short cache only.

Tell what kind of contract an address actually is — live, by asking the chain itself. It probes the contract over the public JSON-RPC (eth_call, no key): an ERC-165 interface sweep (ERC-721, ERC-1155 and their metadata/enumerable/royalty extensions) plus an ERC-20 function probe (name, symbol, decimals, totalSupply), and classifies the address as an ERC-20 token, an NFT (ERC-721), a multi-token (ERC-1155), a plain contract or an externally-owned account. A dedicated endpoint returns a token's live on-chain ERC-20 metadata — working for ANY token, including brand-new ones no token list has yet indexed. The "what is this address" primitive every wallet, explorer, scanner and security tool needs, across Ethereum, Base, Arbitrum, Optimism, BNB, Polygon and more. Reads straight from the chain; live, short cache only.

Query any EVM contract's emitted event logs live via the chain's public JSON-RPC, filtered by address, topics and block range, with every log decoded — block, transaction hash, indexed topics and data. A convenience endpoint decodes ERC-20 Transfer events straight into from / to / value. Unlike a single-transaction receipt lookup, this answers "what happened on this contract over this window" — the indexing primitive behind every block explorer, analytics dashboard and on-chain webhook. Pass raw topic hashes or a known event name like Transfer or Approval. Works on any contract, verified or not, across Ethereum, Base, Arbitrum, Optimism, BNB, Polygon and more. Reads straight from the chain; live, short cache only.

Read any smart contract's raw EVM storage live via the chain's public JSON-RPC, decode each 32-byte word as an address, uint or bool, and resolve proxy implementation pointers across every common proxy standard — EIP-1967, EIP-1822/UUPS and the legacy OpenZeppelin/zeppelinos slot, plus beacon proxies. This is how you find out what a proxy actually points to, who its admin is, or what a contract is storing — even for unverified contracts where source and ABI are unavailable. Give it a chain and an address: read one slot, scan the first N slots to peek at the state layout, or auto-resolve the proxy implementation. The on-chain state-inspection layer for auditors, upgrade monitors and security tooling, across Ethereum, Base, Arbitrum, Optimism, BNB, Polygon and more. Live, short cache only.

Fetch any smart contract's deployed EVM bytecode live from the chain's public JSON-RPC, disassemble it into human-readable opcodes, and extract the 4-byte function selectors from its dispatcher. Unlike source-verification or 4-byte directories, this works on ANY deployed contract — verified or not — so it reveals the raw on-chain logic of contracts nobody has published source for. Give it a chain and an address and get the runtime bytecode, a full offset-by-offset opcode disassembly (paged), and the detected function selectors. The reverse-engineering layer for auditors, MEV searchers and security tooling. Reads straight from the chain across Ethereum, Base, Arbitrum, Optimism, BNB, Polygon and more.

A live ERC-20 token metadata directory aggregated from the curated, on-chain token lists that wallets and dApps actually trust — Uniswap Labs Default, CoinGecko, 1inch, Aave and the Optimism Superchain list — read keyless from their public endpoints. Resolve any token contract address on any chain to its canonical name, symbol, decimals and logo; list a curated set in full (paged, filterable by chain); search across every list by symbol or name; and discover a token's bridged addresses on other chains. The metadata layer every wallet, swap UI and portfolio tracker needs before it can safely display or transact a token. Live, short cache only — nothing stored.

Convert a timestamp or date into the block number that was live at that moment on any of 100+ blockchains, keyless. On-chain analysts, indexers and dashboards constantly need "what block was chain X at time T" to query historical state, and "which blocks cover this time window" to scan a period. This API answers both — for a single moment and for a date range (returning the start and end block plus the block count and average block time). Live, nothing stored. The timestamp-to-block layer for EVM and non-EVM chains alike. Backed by the open DeFiLlama coins API.

Live circulating supply, chain distribution and supply history for any stablecoin, keyless. For one stablecoin (USDT, USDC, DAI, USDe) get its total circulating supply, peg type and mechanism, price, 1d/7d/30d supply change and market dominance; the per-chain breakdown of where that supply actually lives; and the circulating-supply history over time, for the whole asset or a single chain. Search 370+ stablecoins to find an id. Live, nothing stored. The single-stablecoin supply layer for treasury, risk, research and dashboard apps — distinct from whole-ecosystem stablecoin feeds, this is one stablecoin in depth.

For any Safe address on any supported chain it returns the multisig configuration — the owner signers, the signature threshold (the M-of-N), the current nonce, the enabled modules, guard and contract version — and the Safe token balances (native + ERC-20, with symbols and amounts). The multisig-inspection layer for DAO treasuries, security, due-diligence, wallet and dashboard tooling. Live, nothing stored. Backed by the open Safe Transaction Service.

Live detail and full APY/TVL history for any DeFi yield pool, keyless. Unlike current-yield screeners, this is the per-pool time dimension: look up a pool by its id for its current APY (base + reward), TVL, risk flags and forecast, then pull its APY and TVL over time to judge whether a headline yield is sustainable or a fading incentive. Search 15,000+ pools by token, project or chain to find a pool id. Live, nothing stored. The yield-history layer for farming, allocation, backtesting and risk apps — distinct from current-yield lists, this tracks a single pool yield through time.

Give it a chain id and contract address and get the verification status (full / partial / not verified), the compiler and contract name, the deployment info (deployer, transaction, block), the contract ABI (the JSON interface every integration needs), and the verified Solidity source. Live, nothing stored.

Decode Ethereum smart-contract function and event signatures, keyless. Turn a 4-byte function selector (the first 4 bytes of any transaction calldata, e.g. 0xa9059cbb) into its human-readable function signature (transfer(address,uint256)), decode a 32-byte event topic from a log into its event signature, or search the database by name to find a selector. Many selectors have hash collisions — the API flags the original / canonical signature. Backed by the open 4byte.directory database, live. Essential for transaction decoders, block explorers, wallets, security tools and on-chain analytics — the signature-decoding layer for any EVM tooling.

Historical price for any crypto token by its on-chain contract address, keyless. Unlike current-price APIs, this is the time dimension: a price chart over any window, the price at any past date or timestamp, the percentage change over a period, and the token first-ever recorded price. Works for any token on any chain by chain:address (and coingecko:id), covering long-tail tokens centralized APIs miss. Live, nothing stored. The token price-history layer for charting, backtesting, accounting, tax and analytics apps — distinct from current-price and coin-slug APIs, this prices a token HISTORY by contract address.
