The [`Web2Json`](/fdc/attestation-types/web2-json) attestation type has no configured source on Flare Mainnet or Songbird. [`FdcHub.requestAttestation`](/fdc/reference/IFdcHub#requestattestation) reverts for `Web2Json` on those networks.

## What providers should do[​](#what-providers-should-do "Direct link to What providers should do")

With no remaining `Web2Json` sources on Flare Mainnet or Songbird, the `web2-verifier` service has nothing further to serve.

Follow-up [`flare-systems-deployment`](https://github.com/flare-foundation/flare-systems-deployment) and [`fdc-suite-deployment`](https://github.com/flare-foundation/fdc-suite-deployment) releases will remove the configuration entries and the service definition.

Remove any remaining Web2Json source or verifier settings from your FDC client and verifier deployment. Those settings no longer correspond to a live source.

## Testnets[​](#testnets "Direct link to Testnets")

The `Web2Json` attestation type is deprecated on all networks, including **Coston and Coston2**. Developer guides for it are no longer maintained. Applications that need Web2 data should use a [Flare Confidential Compute (FCC)](/fcc/overview) extension instead.
