    The card is served from the API host, which is the provider's only web property beyond a
    content-free SPA at agmsg.world (probed 2026-09-19: agmsg.world 404s both well-known paths).
    api.agmsg.world is the host named in the provider's llms.txt, developer-ai.txt and identity.json,
    the card's provider.organization is "AgMsg" and provider.url is https://api.agmsg.world, and the
    same host serves the OpenAPI whose info.title is "AgMsg" - ownership is not in question.

    resources: >-
      a 40-entry map of absolute URL -> OpenAPI operation object (the entire REST surface, inline),
      which is why the card is 45KB; not an AgentCard field
grade_basis: >-
  Graded against A2A 1.0.0 hard checks: capabilities is an OBJECT (pass), skills is an ARRAY (pass),
  protocolVersion is ABSENT (FAIL). One hard failure makes the grade flavored. The optional
  preferredTransport is also absent, and the card's url is the REST API root rather than an A2A
  JSON-RPC endpoint: a message/send POST to it on 2026-09-19 answered HTTP 405 {"detail":"Method
  Not Allowed"} with Allow: GET, which a2aregistry.org independently records ("Agent card is valid
  but the A2A endpoint returns 405 Method Not Allowed", task_conformance passed: false). So this is
  an A2A-shaped discovery document for a REST+x402 API, not a callable A2A agent.
deviations:
- field: protocolVersion
  observed: absent
  hard: true
  note: Required by A2A 1.0.0 (and present as protocolVersion since 0.3). a2aregistry.org lists it as "unknown".
- field: preferredTransport
  observed: absent
  hard: false
- field: url
  observed: https://api.agmsg.world
  hard: false
  note: >-
    Points at the REST root. There is no JSONRPC/GRPC/HTTP+JSON A2A binding: POST / with a JSON-RPC
    message/send envelope -> 405, Allow: GET; /a2a -> 404. Nothing in the card or the docs claims
    a task/message endpoint exists.
- field: documentationUrl
  observed: https://api.agmsg.world/docs
  hard: false
  note: 'Answers 404 {"detail":"Not Found"}. The provider''s real documentation is /openapi.json and /llms.html.'
- field: skills[]
  observed: 8 entries mirroring the OpenAPI tags
  hard: false
  note: >-
    Each skill is an OpenAPI tag group - id is the tag, description is "Endpoints related to <tag>",
    examples[] are the operation summaries. They describe REST capability groupings rather than A2A
    task skills, and carry no per-skill inputModes/outputModes.
- field: additional top-level keys
  observed: contact, x-payment-info, resources
  hard: false
  note: Non-standard extensions; x-payment-info is the useful one (facilitator and payTo for x402).
