description: 'CarMD specializes in automotive diagnostics and insights, selling the CarMD Connect vehicle-health device and
  publishing the CarMD Vehicle Health Index. Its developer story has two very different halves today. The historic CarMD Vehicle
  API (CarScan) — code definitions, vehicle images, repair and upcoming-issue prediction — is documented at api.carmd.com
  and still linked from the carmd.com footer, but that host refused TCP connections on ports 80 and 443 when probed on 2026-08-27,
  and the old carmd.com/api pricing page now returns 404. Meanwhile the rebuilt carmd.com storefront serves a live, anonymous
  agent surface: an llms.txt, a Universal Commerce Protocol merchant profile, a working MCP endpoint with thirteen commerce
  tools, and an anonymously introspectable Storefront GraphQL API.'

  description: 'CarMD''s vehicle API (marketed as CarScan) provides access to OBD-II code definitions, vehicle images, repair
    information and predicted upcoming issues. Registration issues credentials that are sent on every request. STATUS 2026-08-27:
    unreachable. api.carmd.com DNS-resolves to 54.86.119.234 but TCP 80 and 443 are both closed, so neither the documentation
    at api.carmd.com/member/docs nor the API itself could be reached from two independent networks. No machine-readable contract
    for this API is published anywhere this run could find.'

    shop.name "CarMD" with primaryDomain https://carmd.com — confirming the endpoint belongs to this company. Catalog and
    content reads are open; customer-scoped fields require a customer access token or the OIDC flow at carmd.com/.well-known/openid-configuration.
