Check a receipt
Is this result what VVDex recorded?
Paste a receipt or upload the file. VVDex recomputes every hash, checks the signature and grades the recorded answers again where it can. No account needed.
Nothing checked yet
The result of each check shows here: format, digest, signature, result hashes, per-model counts and the re-graded answers.
What a pass means
A valid receipt was signed by VVDex and has not changed by a single byte since. For a Forge exam each attempt also names the digest of the sealed record it was graded from.
It does not certify that a model is fit for any purpose. It describes one run: these questions, these answers, these grades. For custom endpoints the model’s name is what its owner reported.
Check it yourself
You can also check a receipt without asking this page: with the CLI (vvdex receipt verify receipt.json), or offline against VVDex’s public key (/api/v1/receipts/public-key). The receipt format page explains every field.
