About

API3 delivers first-party oracle data where the data provider signs the API response directly, removing the intermediary node. Its dAPIs aggregate signed first-party feeds and support OEV (oracle extractable value) recapture, returning MEV-style value to dApps. Used for stablecoin and DeFi price feeds.

Pioneered first-party oracles and OEV recapture.
