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.
PlotAPI publishes 1 API on the APIs.io network. Tagged areas include Automotive, Vehicle Data, VIN, MOT, and Auto Parts.
PlotAPI’s developer surface includes documentation, signup flow, engineering blog, and 2 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/plotapi: open an issue to ask a question, or submit a pull request to add artifacts.

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.
