Prove Before Act
● Identity checkedAI agent accountability · Official vendor documentation reviewed 2026-10-07
Prove Before Act is an agent-accountability pattern with xProof as its reference implementation. An integration hashes a declared decision basis before execution, anchors that commitment and links a result record for public verification. API and MCP paths help operators build evidence around consequential agent actions.

Is Prove Before Act right for you?
A good fit for
Agent developers recording explicit pre-action commitments and inspectable result links.
Before you choose
The system does not block actions at runtime; operators must enforce their own gate. A commitment proves a recorded hash, not private intent, the truth of a claim or arbitrary off-chain execution. It is not a compliance certification or legal opinion.
Build the gate in your agent runtime
Record a clear intended action and declared basis without requesting hidden chain-of-thought. Hash locally, request anchoring and check independent confirmation before your own runtime permits the action. Link the observed result and retain the original record needed to verify the matching hash.
Per-proof fees and evidence limits
The homepage lists ten free proofs and a live rate of $0.01 per certification, with the pricing API as the current authority. No monthly subscription is inferred. Blockchain evidence can support review but cannot certify intent, all off-chain behavior or legal/regulatory compliance.
