Most agent authorization protocols enforce against a policy the operator defines. AuthProof is different: your users sign the authorization object with their own private key, and that signature gates execution. Before any action runs, the live model state is measured and compared to what was measured at authorization time. Drift blocks execution. The user's intent is the constraint, not an operator-managed policy that can be rewritten after the fact.
Start freeMost AI agent deployments use a trust score. Good action, score goes up. Bad action, score goes down. Sounds reasonable. But a patient attacker does one bad thing, one good thing, one bad thing, one good thing. The score never hits zero. The damage accumulates. Your account drains. Your data leaks. Slowly. Quietly. Until it is too late.
If your AI agent did something unauthorized today could you prove what it was authorized to do before it acted?
The user signs a receipt that specifies exactly what the agent can and cannot do. This happens before the agent acts -- not after. The receipt is the constraint, not a log.
Every agent action is verified against the signed receipt before execution. Anything outside scope is blocked automatically. No exceptions. No bypasses. The receipt is not advisory -- it is enforced.
Every action is logged with a tamper-evident chain. Export a signed audit package for any compliance review in seconds. Your auditor gets proof that predates execution -- not a log reconstructed after the fact.
Create a receipt and test an action -- no account required.
Fill in the form and click "Create Receipt" to generate a receipt.
Uses the allowed/denied lists from Step 1. Generates 6 - 8 realistic actions and shows live PERMIT / DENY decisions.
