Verify a Proof

Drop one credentialed audio file. We’ll confirm its proof, signer, and exact audio binding — free, with no account. Audio that came with a separate sidecar file can still be checked that way.

Privacy & file handling

Your audio is uploaded only to check its fingerprint against the proof. It lands in a short-lived store that clears automatically — it isn’t reused or added to anything.
