API3

The API3 entry concerns a first-party oracle network whose core mechanisms are first-party oracle architecture and Airnode serverless oracle nodes. Supporting mechanisms include OEV auction value capture, dAPI data feeds, and API provider direct publishing. The role of oracle extractable value recapture helps define how information is published, checked, queried, or consumed. Coverage of API3 should connect DAO-governed oracle network, API3 Market feed service, and signed data endpoint responses with update, governance, and security work at API3. Applications using API3 data and assets referenced by signed data endpoint responses remain separate; this tag concerns API3 infrastructure and methodology.
