# API3
> API3 is a collaborative project that delivers decentralized oralce services by enabling API providers to operate their own 'first-party' nodes. By eliminating middleman node operators, the protocol aims to provide more transparent, secure, and cost-efficient data feeds for decentralized applications. Its flagship products include dAPIs and the OEV Network, a ZK-rollup designed to capture and return value to DeFi protocols.
