    interchange.io is a Scope3-operated domain, not a third party. Its SPA shell declares
    og:url https://scope3.com/ and twitter:site @Scope3data; https://api.interchange.io/.well-known/oauth-authorization-server
    names https://identity.scope3.com as a co-equal authorization server and
    https://docs.interchange.io as its service_documentation; and the OpenAPI documents served
    from api.interchange.io carry info.title "Scope3 Buyer API" / "Scope3 Storefront API".
    Scope3 Interchange is the product name for the agentic-advertising platform.

conformance:
  spec: A2A 1.0.0
  grade: near-conformant
  protocol_version: '0.3'
  preferred_transport: HTTP+JSON
  hard_checks:
    capabilities_is_object: true
    protocol_version_present: true
    skills_is_array: true
  deviations:
  - supportedInterfaces-instead-of-additionalInterfaces
  - protocolVersion-not-full-semver
  grade_note: >-
    All three A2A 1.0.0 hard checks pass and every optional field (preferredTransport,
    defaultInputModes, defaultOutputModes) is present, but the card publishes the non-spec
    key `supportedInterfaces` where A2A 1.0.0 defines `additionalInterfaces`, and declares
    protocolVersion "0.3" rather than "0.3.0". Graded near-conformant rather than conformant
    so the field-naming deviation is not credited away.

    The unauthenticated health endpoint https://api.interchange.io/health reports
    services.a2a "ready" and services.mcp "ready", so the A2A posture is live rather than
    documentation-only. The MCP endpoints are catalogued in mcp/scope3-mcp.yml.
