API3’s dAPIs are aggregated from first-party oracles* directly on the native chain. This means that you always know where your data comes from and never have to rely on cross-chain bridges as a centralized point of failure for your dApp**.

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.
