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.

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.

STON.fi API

Live data from STON.fi, the largest decentralised exchange on TON (The Open Network, the Telegram-native blockchain). The overview endpoint returns the DEX's current total value locked plus lifetime volume, wallets and trades. The pools endpoint returns the top liquidity pools by volume, APY or liquidity — each with its token pair, last price, base/quote volume and liquidity, LP token USD price and APY. The assets endpoint searches STON.fi's token registry by symbol and returns each token's live USD price, decimals and contract address. Read live from STON.fi, nothing stored. The only TON-native DeFi feed here — distinct from Ethereum, Solana and Sui DEX feeds — this is STON.fi's own TON DEX pool, volume/APY and token-pricing layer.

Cetus API

Live data from Cetus, the largest concentrated-liquidity (CLMM) DEX on Sui, which runs most of Sui's on-chain swap volume across thousands of pools. The pools endpoint returns the top pools by TVL, volume or APR — each with its token pair, fee tier, total liquidity, 24h volume and fees, the fee APR and reward APR, and the current price. The pool endpoint returns one pool's full state by address. The search endpoint finds pools by token symbol. Read live from Cetus, nothing stored. This is Cetus's own Sui CLMM pool, TVL/volume/APR and pricing layer — distinct from Ethereum and Solana DEX feeds, lending, staking and oracle APIs, and the only Sui-native DeFi feed here.

Across Bridge API

Live cross-chain bridge data from Across, one of the largest intent-based bridges, which moves USDC, ETH, WBTC and other assets between Ethereum and its rollups (Arbitrum, Base, Optimism, Polygon, zkSync, Linea, Blast, Scroll and more) using a relayer network and a single unified liquidity pool. The quote endpoint prices a bridge transfer — the relayer capital fee, gas fee, LP fee, total fee, the amount received and the estimated fill time. The routes endpoint lists every supported bridge route (origin chain, destination chain, token). The limits endpoint returns the min and max bridgeable amount for a route. The chains endpoint lists supported chains. Read live from Across, nothing stored. This is Across's own cross-chain bridge fee, route and fill-time layer — distinct from DEX, lending, staking and price feeds.
