IWeb2JsonVerification (deprecated)

Deprecated

The Web2Json attestation type is deprecated and this page is no longer maintained. To bring Web2 data onchain, build a Flare Confidential Compute (FCC) extension instead. The Weather Insurance Extension guide shows an extension that fetches data from a Web2 API.

IWeb2JsonVerification is the verifier surface for the Web2Json attestation type. It is one of the parent interfaces inherited by IFdcVerification — in practice most consumers call verifyWeb2Json through ContractRegistry.getFdcVerification() rather than holding a separate IWeb2JsonVerification reference.

Sourced from IWeb2JsonVerification.sol on GitHub.
