description: Automotive and property data API. The published surface covers US VIN histories and vehicle
  specifications, UK MOT records, auto parts fitment catalogues, vehicle valuations, and property listings
  for the UK and US markets, served as typed JSON over a single REST endpoint. Positioned for AI agents
  and for developers who would otherwise integrate several gated data sources separately. The product
  is real and live; what is not public is the interface — documentation, the API reference and key issuance
  all sit behind an account sign-in, and the machine-readable artifacts the site advertises are not currently
  served.

  round: '2026-08-19'
  admitted_from: 'Add-API form submission plotapi-0055b91c at 22:11:55 UTC (gate confidence 25, reason
    low_confidence) and api-search/inbox issue #11 opened four minutes later by the same party. LISTED
    rather than declined: a valid company with a real API gets an entry, and the score is what tells them
    how it reads from outside.'
  the_blocker_is_the_login_not_the_missing_files: https://plotapi.co/dashboard/docs returns 200 but only
    1,090 bytes of visible text carrying six sign-in prompts — it is an account wall, not documentation.
    /docs, /api-reference and /pricing all 404. So no operation, parameter, response shape, rate limit
    or price is readable by anyone without an account, which is why this entry carries a single undescribed
    API rather than an operation inventory.
  advertised_artifacts_not_served: 'The submitted apis.json URL and two files linked in the site footer
    all return the site 404 page: plotapi.co/apis.json, /openapi.json and /llms.txt each return exactly
    11,358 bytes — byte-identical to an invented control path (/zzz-not-real-9137). Checked with both
    a default client user-agent and a browser user-agent; identical either way, so this is not bot filtering
    hiding them. They are advertised and not served.'
  provenance: Nothing here is derived or modelled. The single API entry records what the site states about
    itself; no operations are asserted because none are readable.
  flagged_for_review: Marketing copy leads on bypassing portal blocks and enterprise compliance forms
    and names AutoZone, Copart, Zillow and Rightmove as sources. How data is obtained from named third
    parties is a separate question from the artifact gaps above and is NOT settled by this listing. Recorded
    so it is not lost.
