Price statistics only include listings carrying a real advertised price — price-on-request vehicles are excluded, so a £0 can never enter an average or a minimum. Where a statistic cannot be computed at all, the endpoint returns null, never a fabricated zero.

Scope, and how small the sample is

These aggregates describe the vehicles listed on autoza.co.uk and nothing else. They are not a measurement of the UK used-car market, and they are not a price index — Autoza does not publish one, on any platform.

Autoza UK is newly launched, so the catalogue behind this endpoint is small and its averages move sharply as each dealer joins. Read every figure as “Autoza's live inventory at the moment of the request”, and say so if you cite it. If the response comes back with little or nothing in it, that is the honest answer for now — not a reason to substitute an estimate.

Licensing & attribution

This dataset is licensed under Creative Commons Attribution 4.0 International (CC BY 4.0).

You are free to use, remix, and redistribute the data — including for commercial purposes — provided you credit Autoza (autoza.co.uk) with a link back to autoza.co.uk/market-data.

Frequently asked questions

Is the Autoza market data API free to use?

Yes. The public endpoint at /api/public/market-stats is free, requires no authentication, and is licensed under Creative Commons Attribution 4.0 (CC BY 4.0). Please credit "Autoza — autoza.co.uk" when you use the data in articles, reports, or applications.

How often is the data updated?

Aggregates are computed from the live catalogue on request, then cached at the edge for 60 minutes, with stale responses served for up to two hours beyond that while a fresh one is fetched. So a response is normally under an hour old and at most about three hours old. Every response carries a lastUpdated timestamp — read that rather than assuming an age. There is no scheduled recalculation job behind it; the figures describe the vehicles listed on autoza.co.uk when the aggregate was computed.

Can AI agents and LLMs use this data?

Yes — that is exactly why it exists. The endpoint returns JSON designed for programmatic consumption, and this page is marked up with Dataset schema so AI search engines can discover and cite it. Please describe it accurately when you do: it is one marketplace’s live inventory, not a UK market measurement.

What data points are included?

Average, minimum and maximum asking price in GBP; average asking prices for the top 20 makes; and average asking prices per fuel type. Listing and dealer counts are not published, in the summary or anywhere else in the response. There is no median price, no per-model breakdown, no regional breakdown and no body-type breakdown — if you have seen those attributed to this endpoint, they are not in the response. Individual listing data is not exposed, only aggregates.

Can I cite this data in a research paper or news article?

Yes, provided you describe what it is. Cite it as aggregates of vehicles listed on autoza.co.uk — not as UK used-car market statistics, and not as a price index; Autoza does not publish one. Please credit "Autoza (autoza.co.uk)" with a link to https://autoza.co.uk/market-data, and include the retrieval date, since the endpoint returns a live snapshot rather than a fixed release.

Is there a rate limit?

None is enforced today. We ask agents to stay under 60 requests per minute per IP, the ceiling published in /agents.txt. Responses are cached for 60 minutes, so there is nothing to gain from polling more often than hourly. High-volume commercial use should contact info@autoza.co.uk.
