x-coverage:
  state: covered
  reason: covered
  detail: 'The API reference at api.contactout.com documents 27 REST operations and a hosted OAuth-gated MCP server at contactout.com/mcp; no provider-published machine-readable contract exists, so the OpenAPI was generated from that reference (x-generated-from: documentation).'
