This record was stored by Fuentio when the check ran. It has not changed since.

The same proof as JSON (API) ↗

A proof code never shows who ran the check.

What a proof code shows

  • The outcome: verified, partly verified, not verified, or not enough data, with the reasons.
  • The company: its name, its Fuentio ID and the identifier checked.
  • Each check and its result.
  • The official sources, with links, licences and fetch dates.
  • When the check ran, to the second (UTC).
  • The data fingerprint: anyone can see that the stored answer hasn't changed since.
