C
Conformance score: 60/100
Catalogue listing, not an A2A agent: a paid API listed by agentic.market. Scored on the 3 criteria that apply (24 of 40 points, scaled to 100); the A2A card criteria do not apply.
click to expand breakdown ▾ click to collapse breakdown ▴
n/a Agent card n/a
Not applicable: a paid API listed by agentic.market. The host serves no A2A agent card at /.well-known/agent-card.json, so the card criteria are not scored.
partial Live endpoint 15/25
Our probe received an HTTP 402 payment challenge from the host: live, but paid.
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: music-production-calc.x402tookit.com (https://music-production-calc.x402tookit.com). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
