How this service works
The Once-Over. A signed JSON audit report — verdict (ready, not_ready or unreachable), every check and advisory from the published preflight battery, dated, its evidence hash bound into the purchase certificate's attests field — plus a stable report URL serving the record free forever. Instant; one GET at one moment, never monitoring. Full listing: https://scvd.store/menu/service_audit. MCP tool: buy_service_audit.
Output
A signed JSON deliverable containing: a verdict of 'ready', 'not_ready', or 'unreachable'; each preflight check result and advisory from the published battery; a certificate with date, cert_id, and patron number; an evidence hash bound into the attests field; a badge URL; and a stable permanent report URL where the record is accessible free forever. Also returns the USDC paid and an ed25519 signature for verification.
Example use cases
Pre-launch x402 compliance check
“Before I go live, can you audit https://api.myapp.com/data-feed to check if it's properly set up for x402 payments? I want a signed report I can keep, and put 'DataFeed Bot' as the agent name on the certificate.”
Vetting a third-party paid API
“I'm thinking of integrating https://partner.example.com/api/insights into my pipeline — can you run the Once-Over on it and tell me if it's actually x402-ready or if there are issues I should know about?”
Generating a trust certificate for a marketplace listing
“I need a signed audit certificate for https://mystore.example.com/api/buy/widget so I can show buyers it passed all preflight checks — run the audit and label it 'WidgetStore Agent' on the badge.”
Technical details
Endpoint
GEThttps://scvd.store/api/buy/service_auditWhen to prefer
Choose this endpoint when you need a one-time, point-in-time signed audit of a specific x402 endpoint — not ongoing monitoring. It is ideal for pre-launch compliance checks, marketplace trust certification, or due-diligence before integrating a third-party x402 API. Prefer this over the Conformance Watch (which monitors over time) when you want an immediate snapshot with a permanent certificate and evidence hash, rather than recurring surveillance.
Side effects
- URL points to scvd.store's own hostname (refused — self-audits not allowed)
- Target URL is not publicly reachable (verdict: unreachable)
- URL is not HTTPS or uses a non-default port (rejected at input validation)
- Target endpoint does not respond with a 402 (noted in check results, verdict: not_ready)
- Payment of $5 USDC via x402 fails or is not completed (no audit performed)
- agent_name exceeds 80 characters (input validation error)
