List-Smith-Production

list-smith-production.up.railway.app · list-smith-production.up.railway.app

Repair one x402 route's Bazaar discovery metadata in one call. Send a resource URL and one real sample output; get the defect report plus a complete discovery package — full output schema inferred from the sample, a sub-500-char description with a use-when sentence, OpenAPI and well-known snippets, paste-in instructions — that ships only after passing both x402 SDK validators. Use this when your listing is hollow, invalid, or invisible in the Bazaar.

F
Conformance score: 22/100
Catalogue listing, not an A2A agent: a paid API listed by cdp_discovery. Scored on the 3 criteria that apply (9 of 40 points, scaled to 100); the A2A card criteria do not apply.

n/a Agent card n/a
Not applicable: a paid API listed by cdp_discovery. The host serves no A2A agent card at /.well-known/agent-card.json, so the card criteria are not scored.
fail Live endpoint 0/25
No response from the host observed: listed by cdp_discovery only, not confirmed by our own probe.
n/a Protocol version n/a
Not applicable: no A2A agent card served.
n/a JWS signature n/a
Not applicable: no A2A agent card served.
n/a Uptime track record n/a
Not applicable: our probes looked for an A2A agent card, which this host does not serve. That says nothing about the API's availability, so it is not graded.
n/a Skill declaration n/a
Not applicable: no A2A agent card served.
partial Verified Identity 5/10
Provider declared: list-smith-production.up.railway.app (https://list-smith-production.up.railway.app/). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
