API3 is a blockchain-native, decentralised API (dAPI) network that provides reliable data feeds for smart contracts, aiming to eliminate the need for third-party intermediaries in data provision. By enabling API providers to directly offer services to smart contracts, API3 enhances the functionality and autonomy of blockchain applications. The API3 token governs and secures the network, facilitating collective management of the protocol and allowing stakeholders to vote on key decisions. It also enables revenue sharing among participants, underpinning a system where data providers have a direct stake in the network.
