How this service works
The Opening Day. REQUIRES ?url= on the paid request — a signed request without it is refused before the gate and no money moves. The launch check's signed JSON walk record (verdict, every stage, what was paid, the settlement transaction where one came back), its evidence hash bound into the purchase certificate's attests field; a conformance watch opened on the same door for seven days, each daily pass signed alone at a history URL; the host's endpoint passport URL; and one …
Output
A JSON object containing a signed ed25519 conformance certificate with a unique cert_id, the patron number, a badge SVG URL, a permanent verify URL, the ISO timestamp, the amount paid in USDC, a tip field, and a deliverable text field containing the Opening Day item itself. The certificate can be independently verified at the returned verify_url.
Example use cases
Pre-launch x402 endpoint audit
“I'm about to launch my x402-gated API at https://api.myservice.com/gated/report — can you get it a conformance certificate from SCVD General Store before I go live? Use the agent name 'MyService Launch Bot' and say this is a pre-launch conformance check.”
Proving x402 readiness to investors
“I need a signed, third-party attestation that my x402 payment endpoint at https://commerce.myco.io/api/v1/access is properly implemented — get me an Opening Day certificate from SCVD with agent name 'MyCoAgent' so I can show investors it passes real conformance checks.”
Earning a patron badge for agentic store
“Get me a patron badge and permanent cert from Sean-Claude Van Damme's General Store for my x402 door at https://agent.toolhouse.ai/paid/summary — name it 'Toolhouse Agent' on the certificate.”
Technical details
Endpoint
GEThttps://scvd.store/api/buy/opening_day?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an independent, signed, blockchain-anchored conformance certificate proving that a specific x402 endpoint correctly handles real payment attempts and passes repeated daily conformance checks. It is the right choice over self-testing or informal checks when you want a permanent, verifiable, third-party attestation with a patron badge — particularly for pre-launch validation, investor proof, or integrating into an x402 directory listing. It is not appropriate for general HTTP health checks, non-x402 APIs, or cases where you need free/unsigned conformance testing.
Side effects
- Supplied URL uses the scvd.store hostname (refused by policy)
- URL is not HTTPS or uses a non-default port (schema validation failure)
- Target x402 endpoint is unreachable or does not respond with a 402 (conformance failure)
- Payment settlement fails on-chain (transaction timeout or insufficient balance)
- URL field missing or malformed (400 schema validation error)
- Agent name exceeds 80 characters (validation error)
