How this service works
scvd.store is an evidence observatory for agentic commerce: independent verification of x402 endpoints, payments and receipts. Before an agent pays an x402 endpoint, we check that it can be paid. After it pays, we check the signed receipt. Over time we watch endpoints and publish a dated, signed corpus. Sellers use it to prove a door works; buyers use it before spending. Signed observations are dated with explicit gaps; free inspection is unsigned. Not escrow, not a rating, not a guarantee.
Output
A JSON response containing the full A2A Repair Kit text as a 'deliverable' field, an ed25519 signature over a certificate record, a unique cert_id, a sequential patron number, a badge SVG URL, a verify URL for the certificate, and the amount paid in USDC.
Example use cases
Agent onboarding with repair kit
“My agent just published its A2A 0.3.0 card at https://agent.myco.io/.well-known/agent.json — go buy it the A2A Repair Kit from SCVD, use 'MyCoAgent' as the name on the certificate, and give me back the deliverable text and badge URL.”
Certifying a newly deployed agent
“I just deployed a new AI agent with its card at https://bots.example.com/a2a/agent.json. Purchase the A2A Repair Kit for it from the SCVD General Store, with purpose 'Initial deployment certification for ExampleBot', agent name 'ExampleBot'.”
Collecting patron badge for agent portfolio
“Get the A2A Repair Kit from SCVD for my agent card at https://demo.acme.ai/agent.json — I want the patron number, badge SVG URL, and the full repair kit text so I can add them to my agent's profile page.”

Choose this endpoint when your agent has a published A2A 0.3.0 agent card and you want both the A2A Repair Kit deliverable content and a permanent, ed25519-signed certificate with a patron number and badge — particularly when operating on Base, Polygon, Arbitrum, World, or Solana and paying with USDC via x402 v2.

- Authorization fixture not published at /a2a-desk same-origin path — purchase may be rejected
- Invalid or non-A2A-0.3.0 agent card format at the provided URL
- x402 payment failure — insufficient USDC balance or unsupported chain
- URL missing or malformed (not a valid URI) — schema validation error
- Network timeout fetching the agent card URL
