An Attestloop attestation is a hash-chained record of verified AI-surface fixes. Anyone (an auditor, a buyer, or another AI agent) can recompute the chain and confirm it was not altered. No account, no trust in us required.
A valid sample is loaded on the left. Click Verify chain to recompute its hashes in the browser, or verify from your terminal:
curl -X POST https://attestloop.com/api/verify \ -H 'content-type: application/json' --data @attest.json
The same code that issues an attestation verifies it, so "we computed it" and "you checked it" are identical.
