How are dAPIs different?

API3’s data feeds, dAPIs, get their data directly from the source without relying on third-party middlemen. The dAPI aggregation contract resides on the same chain as the consumer dApp, meaning the data is never bridged over and exposed to bridge exploits. This maximizes the reliability and transparency of our feeds, resulting in safer DeFi for everyone.

For Developers

Data services for developers who prioritize security, transparency and accuracy.

API3 builds solutions that bridge the gap between off-chain data and on-chain applications with maximal security and minimal latency. Below you can explore our currently available services.

Data feeds

Native-chain aggregated price reference data feeds for a wide variety of assets across numerous networks including Polygon (PoS & zkEVM), Arbitrum, Optimism, Blast, and many more.

QRNG

Free quantum mechanics-derived random number generator for smart contracts, powered by Australia National University Quantum Optics Group and Quintessence Labs.

For Data Providers

Connect your data to decentralized applications.

Airnode is a simple, crypto-free Web3 API gateway that enables API providers to connect their data to decentralized applications running on various blockchains.

ChainAPI is Airnode’s effortless, no-code, GUI-based integration tool that enables an API provider to self-deploy an Airnode in minutes.

Join the API3 Alliance.

API3 Alliance is the largest association of API Providers on Web3. It was formed to promote the use of real-world data in decentralized applications.

DAO

API3 is decentrally governed by its token holders.

As a DAO, the API3 project is governed programmatically through the use of an on-chain voting mechanism, powered by the API3 token.
