KyberSwap API

healthy 3,751 Subscribers

Live DEX-aggregator swap quotes from KyberSwap, which routes a trade across every decentralised exchange and liquidity pool on a chain to find the best output. The quote endpoint prices a swap between two tokens on Ethereum, Arbitrum, Base, Optimism, Polygon or BNB Chain — it returns the amount received, the USD values in and out, the price impact, the estimated gas cost and the DEXs the route passes through. The tokens endpoint lists the supported tokens per chain. The chains endpoint lists supported chains. Read live from KyberSwap, nothing stored. This is KyberSwap's own multi-chain EVM swap-routing and best-price layer — distinct from single-DEX feeds and from Solana swap aggregators.

DEX Aggregators API — oanor API marketplace

DEX Aggregators API

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.

 FX Carry Trade API — oanor API marketplace

FX Carry Trade API

Live carry-trade and rollover analytics that FX traders run before borrowing a low-yield currency to buy a high-yield one, computed on demand from the interest rates you pass in — no key, no cache, nothing stored. The carry endpoint returns the interest-rate differential, the carry income over a holding period, the financing-adjusted yield and the leveraged return on margin, so you see exactly what a position earns. The rollover endpoint returns the daily, weekly and monthly swap — positive when you receive carry, negative when you pay it — the number a broker debits or credits each night. The breakeven endpoint returns how far the spot rate can move against the position before the carry is wiped out: the cushion the carry buys you, and the break-even spot level. This is an interest-rate and carry engine, distinct from pip and lot calculators and price tools: it turns two yields, leverage and time into the income and the risk cushion of a carry trade. The carry trade is one of the most-used FX strategies (think funding in yen to hold a higher-yielding currency), and these are the numbers behind it. Computed locally and deterministically, so it is instant and private. Ideal for FX dashboards, strategy back-tests, position sizers and trading tools. Rates are annual percentages (5.5 = 5.5%). Live, nothing stored. 3 compute endpoints. For live policy rates feed them in from a central-bank or rates API.

 Jupiter Solana DEX Aggregator API — oanor API marketplace

Jupiter Solana DEX Aggregator API

Live data from Jupiter — the leading DEX aggregator on Solana — served from its public API as clean JSON, no cache. Get the live USD price, on-chain liquidity and 24h price change for any Solana token mint (one or many at once); get the best swap route Jupiter finds between two token mints for a given input amount — the output amount, price impact and number of routing hops, the heart of the aggregator; or search Solana tokens by symbol, name or mint and get the top match's price, liquidity, market cap, decimals and holder count. Read live from Jupiter, nothing cached. This is Jupiter's own Solana swap-routing, token-price and token-search layer — distinct from EVM on-chain explorers, other DEX/DeFi feeds and generic price APIs: the live routing and pricing engine of Solana's biggest swap aggregator.

 Superposition API — oanor API marketplace

Superposition API

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.
