  note: 'Served from the apex marketing host (Next.js behind Cloudflare), not from the API host: api.webcrawlerapi.com/.well-known/agent-card.json
    and /agent.json both return a plain-text 404. The 200 is a real served document and not an SPA catch-all - the
    same host answers every other /.well-known/* path (security.txt, openid-configuration, oauth-authorization-server,
    oauth-protected-resource, ai-plugin.json, agent.json, mcp.json) with a 307 to /404, and the body is application/json
    that parses as an AgentCard-shaped object. www.webcrawlerapi.com 301s the path to the apex. The legacy /.well-known/agent.json
    is not served (307 -> /404). Ownership is not in question: provider.organization is "WebCrawlerAPI" with provider.url
    https://webcrawlerapi.com, the card''s openapi_url points at api.webcrawlerapi.com, and the OpenAPI at that
    host names support@webcrawlerapi.com and webcrawlerapi.com/tos.'

    response: 404 page not found
    note: The card's url (https://api.webcrawlerapi.com/v1) is the REST base path, not an A2A JSON-RPC endpoint
      - a JSON-RPC POST to it returns the router's plain-text 404. No A2A responder was found on any host.

    http_status: 200
    note: The card's openapi_url resolves to a real OpenAPI 3.0.3 (3 operations, servers[] https://api.webcrawlerapi.com);
      saved to openapi/_original/webcrawlerapi-com-agent-openapi.json.

    note: This provider entered the harvest backlog via the a2a-registry source; the card above was fetched directly

  rationale: 'Fails one hard check: protocolVersion is absent, so a client cannot tell which A2A revision the card
    targets. Beyond the checklist, url is the REST API base path (https://api.webcrawlerapi.com/v1) rather than
    an A2A endpoint - a JSON-RPC POST there 404s - and the card carries two non-standard members (openapi_url, healthCheckUrl)
    that read as an OpenAPI-style service descriptor wearing the AgentCard shape. What it does well: capabilities
    is an object, skills is a well-formed array with ids/tags/examples/input+output modes, provider and documentationUrl
    are set, and securitySchemes/security use the AgentCard security shape correctly.'
deviations:
- field: protocolVersion
  issue: missing
  severity: hard
  fix: 'Add "protocolVersion": "0.3.0" (or the revision implemented).'
- field: url
  issue: Points at the REST base path https://api.webcrawlerapi.com/v1, which does not answer A2A JSON-RPC (POST
    -> 404 page not found).
  severity: hard-adjacent
  fix: Point url at a real A2A endpoint, or if the intent is REST discovery keep this card but say so - agents that
    follow the A2A spec will POST JSON-RPC here and fail.
- field: preferredTransport
  issue: missing (optional; defaults to JSONRPC, which is not what the url serves).
  severity: optional
- field: openapi_url / healthCheckUrl
  issue: Not AgentCard members. Harmless to spec-tolerant parsers but not portable.
  severity: informational
  fix: Move to additionalInterfaces / documentationUrl, or an extension namespace.
- field: capabilities.pushNotifications
  issue: Declared true. The REST API does support webhook_url callbacks on jobs and feeds, but there is no A2A tasks/pushNotificationConfig
    endpoint behind this card.
  severity: informational
skills_vs_rest:
  scrape: POST /v2/scrape (createScrapeV2 in overlays/)
  crawl: POST /v1/crawl + GET /v1/job/{id} (createCrawlJob, getJob)
  crawling-agent: POST /v1/agent + GET /v1/agent/job/{id} (runAgent, getAgentJob) - the only skill covered by the
    card's own openapi_url document
