Verify a receipt

Verify Alvo’s receipt yourself.

An Alvo AI brief carries a receipt: the AI Act Article 50 disclosure and a declaration that no data went to an external model. Paste one and recompute the check right here — no involvement from us.

How it works

  1. 1Copy the receipt (JSON) from the receipt field in the /api/ai/trading-brief response.
  2. 2Optionally add the declared inputs the hash was bound to — to confirm the receipt is tied to exactly those.
  3. 3Click Verify — the page recomputes the hash and checks the declarations (deterministic, no external model, zero tokens, zero data sent to an external model).

This is a recomputable attestation, not a cryptographic signature. There is no secret key or PKI — anyone can run the same deterministic recomputation and get the same result. That is the point: trust from reproducibility, not from our word.

The /api/ai/receipt/verify endpoint is public and unauthenticated — which is exactly why a receipt can be verified independently. Nothing you paste is stored.
