What is API3?
API3 is a first-party oracle solution launched in December 2020 that provides data feeds and Oracle Extractable Value (OEV) rewards for DeFi projects. The platform offers over 100 data feeds across multiple chains, enabling DeFi protocols to receive OEV rewards wherever they build. API3's proprietary Airnode technology allows API owners to turn regular APIs into blockchain-compatible data sources that can be easily integrated into Web3 applications. Developers can use APIs to connect their apps to real-world data streams.
