API3 is a decentralized oracle project that provides data services for developers and data providers in the Web3 ecosystem. Their dAPIs (data Application Programming Interfaces) aggregate data directly from source-level data providers on native chains, eliminating the need for cross-chain bridges. This maximizes reliability and transparency, making DeFi applications safer for users. API3 also offers additional services such as a quantum mechanics-derived random number generator and Web3 APIs. The project is governed by its token holders through an on-chain voting mechanism.
