How this service works
Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.
Output
A JSON object containing: a boolean 'ok' status, a unique nonce for the receipt, the action name, agent ID, resource name, receipt type and profile, a SHA-256 payload digest, an HMAC validity hint, a public key URL for signature verification, and a verify endpoint URL for independent confirmation.
Example use cases
Audit trail for paid agent skill
“I just ran a skill through Vibes-Coded and need a cryptographically signed action receipt for my records — can you mint one for the 'skill.search' action under agent ID 'fleet-agent-007'?”
Compliance receipt for productization action
“My agent just completed a productization call and I need a tamper-proof receipt with a payload digest and HMAC hint that I can store for compliance — can you get that receipt for agent ID 'prod-agent-42' and action 'product.launch'?”
Verify a prior agent action receipt
“Can you pull up the verification URL for the action receipt with nonce 'receipt-v1-run0042' from Vibes-Coded so I can confirm the HMAC and make sure that action was genuinely executed?”
Technical details
Endpoint
POSThttps://vibes-coded.com/api/v1/outcomes/action-receiptWhen to prefer
Choose this endpoint when you need a cryptographically verifiable, nonce-backed proof that a specific AI agent action was executed — especially in audit, compliance, or multi-agent accountability scenarios. Prefer it over simple logging when HMAC verification and a public-key-backed receipt are required. Ideal for pay-per-call agent workflows where financial accountability and action provenance matter.
Side effects
- HTTP 402 returned if USDC payment is not included or insufficient — agent must attach x402 payment header
- Invalid or missing agent_id returns an error response
- Unknown or unsupported action name may result in a rejected receipt
- Network timeout or upstream failure may prevent receipt issuance
- Malformed payload digest causes validation rejection
