XGuard / operating contract

Verify what was executed

The result includes an execution identifier, request digest, result digest and signed ProofRail evidence. Use xguard_verify_receipt or POST /v1/receipts/verify with the proof and result digest. Public paid outcomes can also include the bound x402 receipt.

A valid signature proves that XGuard signed the evidence and that matching bytes have not changed. It does not establish the factual truth of a web page or model response. Save the response and proof in your own records; capability result recovery currently lasts only while the capability remains valid.
