Can I rely on this?
Paste a registry link, any other link, a digest, a C2PA manifest digest or an id, or drop a file. The answer is the verdict for each record that matches: rely, check or do not rely, the plain reasons, the terms owed and a receipt you can check. Your file never leaves this device: the browser hashes it and sends only the SHA-256.

The registry does not fetch links you paste. A link that is not a registry page is matched as text against the records that name it.

The same check as data
$ curl 'https://aisourceoftruth.com/check?q=<value>&format=json' # this check as data: { query, matches } with each assess receipt
The verdict comes from the world model as of a signed checkpoint, never a score. For soft binding ids from a watermark decoder, use /lookup. To see what a key signed or an agent version touched, use /impact.
