Curve Finance

Curve Finance is a DeFi automated market maker (AMM) optimized for low-slippage swaps among stablecoins and pegged assets across multiple chains. Curve maintains a public read-only REST API at api.curve.finance providing pool, gauge, factory, governance, lending, crvUSD, and TVL data. Smart-contract entry points are the primary write path; the REST API is for indexing and analytics.

Curve Finance publishes 8 APIs on the APIs.io network, including crvUSD API, Deprecated API, Gauges API, and 5 more. Tagged areas include Web3, DeFi, DEX, AMM, and Stablecoins.

Curve Finance’s developer surface includes developer portal, documentation, GitHub presence, engineering blog, and 8 more developer resources.
