Pyth Network API

healthy 4,534 Subscribers

Live cross-asset prices from Pyth, the largest decentralised first-party oracle, which aggregates prices contributed by exchanges, market makers and trading firms and serves them across 90+ blockchains. Pyth covers far more than crypto: around 3,000 feeds spanning crypto, US and global equities, FX pairs, commodities and precious metals. The feeds endpoint searches the feed registry by symbol or asset type; the price endpoint returns one feed's latest aggregate price with its confidence interval, exponent, EMA price and publish time; the prices endpoint returns many feeds at once. Each price carries a confidence band — Pyth's signature measure of how tightly publishers agree. Read live from Pyth, nothing stored. This is Pyth's own multi-asset first-party oracle layer — distinct from single-DEX oracles and single-asset-class price feeds.

GMX API

Live oracle prices from GMX, the leading decentralised perpetual-swap exchange on Arbitrum and Avalanche. Unlike order-book DEXs, GMX executes trades against its GLP/GM liquidity pools at prices set by a keeper-signed oracle that quotes a MIN and a MAX price per token — the execution band traders open and close positions against. The prices endpoint returns every supported token's min/max/mid oracle price and the execution spread; the price endpoint returns a single token by symbol; the tokens endpoint returns the supported-token registry (contract address, decimals, synthetic flag); the spread endpoint ranks tokens by their oracle execution spread (the on-chain cost band of trading that token on GMX). Every endpoint accepts a chain parameter (arbitrum default, or avalanche). Read live from GMX's public oracle, nothing stored. This is GMX's own pool-DEX oracle min/max-price and execution-spread layer — distinct from centralised-exchange tickers, aggregate price feeds and order-book DEX feeds such as dYdX and Hyperliquid.

KyberSwap API

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.

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.
