scvd.store/api/buy/a2a_repair_kit
Task: Find reproducible failures in my A2A agent and hand my developer tested repair instructions. Returns: A signed A2A report, suggested repairs, regression runner URL, private one-use recheck token and finite card-watch history Price: $49 USDC (x402 v2; network from the current quote). Latency: delivered in the purchase response, same request. Verify: GET /api/verify/{id} — free, unlimited, forever (live sample: cert_4dww28dx5j). Constraints: url is the full public HTTPS agent-card URL; no query, fragment, credentials, private address or our own hostname; Before purchase publish /.well-known/scvd-a2a-audit.json on the same origin, with the safe-to-repeat fixture and explicit permission described at /a2a-desk; Only public test data; no secrets, credentials or wallet material; One recheck within 30 days; keep the purchase token private. Removing or expiring the authorization file revokes runtime permission; Seven days of card observations, ending automatically. No automatic renewal; Repairs are suggestions, not source-inspected patches. Code implementation requires a separate quote. The A2A Repair Kit, Check an A2A agent, reproduce its failures, and hand a developer the repairs and regression tests. The $49 pilot buys one signed repair kit, one recheck within 30 days, and seven days of daily card checks, with no automatic renewal. Supports public A2A 0.3.0 JSON-RPC endpoints with an operator-published safe test fixture. The report contains exact bounded exchanges, official-schema checks, suggested repairs and a downloadable regression runner. Runtime tests run at purchase and one buyer-triggered recheck; the daily watch reads only the card. Implementation in your repository is separately scoped. Free card checks and setup: /a2a-desk. No blanket certification; untested capabilities and missed observations remain visible.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
