# Curve Finance DeFi API > Live DeFi data from Curve Finance — the dominant decentralised exchange for stablecoins and pegged assets (StableSwap AMM) — served from its public API as clean JSON, no cache. List every chain Curve runs on and the pool registries on each; pull the liquidity pools on a chain/registry with each pool's USD TVL, underlying coins and prices, amplification coefficient, virtual price and CRV gauge APY (sorted by TVL); fetch one pool's full detail by address; or read a chain's total and per-pool trading volume. Read live from Curve, nothing cached. This is Curve's own StableSwap pool, TVL and gauge layer across Ethereum and 20+ L2s — distinct from on-chain explorers, general DEX-pool feeds and price APIs: protocol-level data for the largest stablecoin AMM in DeFi. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
