How this service works
Verify a hash-linked agent commerce journey and issue a signed portable receipt
Output
A signed, portable receipt attesting that the hash-linked agent commerce journey is valid, including a cryptographic signature, journey integrity status, and a machine-readable proof that can be presented to third parties as evidence of the completed agentic transaction chain.
Example use cases
Post-purchase agentic audit trail
“My AI agent just completed a series of purchases on my behalf — can you verify the entire hash-linked journey and give me a signed portable receipt I can store as proof that each step was legitimate?”
Dispute resolution for agent transaction
“There's a dispute about whether my agent actually completed the full commerce journey — can you run the verification against the hash chain and produce a signed receipt I can share with the other party?”
Compliance record for automated spending
“I need to prove to my compliance team that the agentic commerce journey my bot executed was fully intact and unaltered — please verify the linked hash chain and issue a signed attestation receipt.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/journeys/verifyWhen to prefer
Choose this endpoint when you need cryptographic, third-party-signed proof that an AI agent completed a multi-step commerce journey in its claimed sequence — particularly for dispute resolution, compliance auditing, or presenting portable evidence to external parties. It is distinct from simple payment confirmation because it validates the entire hash-linked chain of events, not just a single transaction.
Side effects
- Invalid or broken hash chain — returns verification failure with details of which link in the journey failed
- Journey not found — if the referenced journey ID or hash does not exist in the system
- Tampered journey data — hash mismatch detected, receipt not issued and error returned
- Malformed request body — missing required journey hash or chain reference fields
- Payment failure — $0.01 USDC x402 payment not completed, endpoint returns 402
