  A2A Agent Card observed at /.well-known/agent-card.json on api.macaroonnetwork.com, the provider's API,
  MCP and A2A host. Grade is measured against the A2A 1.0.0 AgentCard object: 'conformant' passes every
  structural check, 'near-conformant' is correctly shaped but omits optional fields, 'flavored' fails a hard
  check. Provider-published by construction — served from the provider's own host; nothing here is derived
  or generated. The body is saved verbatim in macaroonnetwork-com-agent-card.json.
card:
  file: a2a/macaroonnetwork-com-agent-card.json
  name: Macaroon Network
  description: >-
    Marketplace for agent-purchasable capabilities. Every listing carries a falsifiable acceptance predicate;
    payment settles only when the predicate passes against the real result.

  note: >-
    The card is served ONLY from the API host. The apex (macaroonnetwork.com) and www return the site's real
    HTML 404 (12,830 bytes) for both /.well-known/agent-card.json and /.well-known/agent.json, and a
    negative-control path (/.well-known/macaroonnetwork-com-negative-control-7c2f91ab.json) 404s on all three
    hosts (application/json {"detail":"Not Found"}, 22 bytes, on the API host), so the 200 is a served document
    and not a catch-all. Ownership is not in question: the card's url is https://api.macaroonnetwork.com/a2a,
    the OpenAPI at the same host titles itself "Macaroon Network Agent Services" and declares the
    /.well-known/agent-card.json and /.well-known/agent.json operations (a2a_agent_card__well_known_agent_card_json_get,
    a2a_agent_card_legacy_path__well_known_agent_json_get) and POST /a2a (a2a_jsonrpc_a2a_post), and the
    apex llms.txt, api root JSON and privacy/terms pages all name api.macaroonnetwork.com as the API.

  deviations: []
  observations:
  - No provider{} block, documentationUrl, iconUrl, securitySchemes or security[] — the endpoint is anonymous by design (auth.md), so the absence of securitySchemes is accurate rather than an omission.
  - No capabilities.extensions[] — the card does not declare the a2a-x402 payment extension even though every skill settles over x402; payment is carried in HTTP (402 + PAYMENT-REQUIRED) on the REST execute path rather than inside the A2A task flow.
  - Skills carry id, name, description, tags, inputModes, outputModes but no examples[].
