Verify a receipt

Paste a receipt. It is checked in your browser against Gatefee’s published signing keys. Nothing you paste is sent to us.

What this does, exactly

• It fetches the public keys from https://gatefee.ai/.well-known/jwks.json — and from nowhere else. It never fetches an address found inside what you paste.
• It checks the signature (EdDSA, Ed25519), that the payload is in canonical form, and that the claims are a receipt’s claims — the same code the command-line verifier and the API use.
• You do not need this page. A receipt can be verified offline with any standard JWS library and that key set: the format is documented, with a worked example.

What a valid receipt proves — and what it does not

It proves that Gatefee signed a record saying this document version, with this content hash, was licensed for this purpose, under these published terms, at this time. It shows the publisher’s list price, never what the buyer paid. It is not a statement about how the content was used afterwards, and it is not legal advice.
