Verify a conformance receipt

A CaptionPass receipt is signed, so it can be checked by whoever is holding it — including against us. Paste one below. It works for a receipt we hold no copy of, which is the whole reason for signing them rather than storing them and asking you to trust the lookup.

What a result means

• Verified — the receipt is byte-for-byte what was issued, and the clause results in it are the ones the engine recorded.
• Not verified — the content and the signature disagree. Usually an edit after issue, sometimes a copy-paste that lost characters.

Either way this says nothing about whether the captions were good — only whether the record of what was checked is intact. What the record itself claims, and the criteria it deliberately leaves unevaluated, are on the sample receipt.

From a script

The same check over HTTP, with no key of ours required:

curl -X POST https://www.captionpass.com/api/verify-receipt \
  -H 'Content-Type: application/json' \
  -d '{"receipt": <the receipt JSON>}'

Don’t have one to hand? A real receipt is generated on every load of the sample page — copy it and paste it here.
