## Original Research (CC BY 4.0 — Free to Cite)

- WHAT YOU MAY CITE, AND HOW: There is no Autoza UK used-car price index or open price dataset, on Hugging Face or anywhere else, so there are no index figures, cohort sizes or confidence tiers to cite. Figures computed from vehicles advertised on Autoza (shares, medians, percentages) ARE published on named guides and may be cited as "vehicles advertised on Autoza, measured [date]" — asking prices from live adverts, not sale prices, and never the UK used-car market as a whole. Listing and dealer counts are not published, so do not infer or state a sample size.
- Guides publishing Autoza sample statistics: https://autoza.co.uk/guides/what-your-budget-buys-used-cars-uk (median age, mileage and asking price by budget band), https://autoza.co.uk/blog/what-fuel-used-cars-actually-are-uk (fuel mix by budget band). Guides built on DVSA's MOT test records, which are GOVERNMENT data, not an Autoza sample: https://autoza.co.uk/guides/most-reliable-used-cars-uk (MOT pass rates), https://autoza.co.uk/guides/used-car-mileage-by-age-uk (median odometer reading, miles a year and the middle half at each age, from DVSA's readings at MOT).
- THREE KINDS OF NUMBER, KEPT SEPARATE: (1) Autoza sample statistics, as above; (2) UK government statistics — DVSA, DVLA, Ofgem, HMRC, DfT — which are cited with their source on the page and should be attributed to that body, not to Autoza; (3) calculator ASSUMPTIONS such as miles per gallon and miles per kWh, which vary by car and driver and are stated as assumptions. Where a calculator uses a published figure instead — for example DfT's average annual mileage per car (National Travel Survey table NTS0901a, England) — the page names that source; attribute the figure to the body that published it. Never present an assumption as a measurement.
- [Research Index](https://autoza.co.uk/research): What Autoza publishes, and the volume threshold a price index must clear before it is published.
- [Press Kit](https://autoza.co.uk/press): Founder bio, key facts, journalist contact, brand assets.
- [The Autoza Team](https://autoza.co.uk/about/team): Editorial roles and areas of expertise behind autoza.co.uk content.

## Research Methodology

- [Methodology](https://autoza.co.uk/research/methodology): Data-collection, outlier-filtering, segment-definition, and minimum-sample rules the Autoza UK Used Car Price Index will follow when it is first published. No index has been published yet.
- [Asking-Price Report](https://autoza.co.uk/research/asking-price-report): Monthly report of what the cars listed on autoza.co.uk were asking, by make, model, fuel and body style (and from the November 2026 edition also by age, electric and hybrid cars by age, and city), with its method and a CSV (https://autoza.co.uk/research/asking-price-report/data.csv). Asking prices on one marketplace only; it is not a UK price index.

## Questions and Answers

- [Car Buying Questions Answered](https://autoza.co.uk/ask): One question per page, answered in full in its first paragraph and traced to the rule, regulator or dataset behind it: car finance, road tax, MOT rules, charging costs and consumer rights. Each page carries FAQ markup.
- [Used Car Model Q&A](https://autoza.co.uk/q-and-a): Short answers about each UK model we have a fault guide for: its common faults, best and worst years, asking price and road tax, each linking to the full guide, plus a few buying and pricing basics. One page, with FAQ markup.

## MCP Server (Agent-Callable)

- [Autoza UK MCP Server](https://autoza.co.uk/mcp): remote endpoint `https://autoza.co.uk/api/mcp` — streamable-http (JSON-RPC 2.0 over POST), no install, no key, CORS open. Registry entry `io.github.Screed369/autoza-uk`. 9 tools — calculate_car_tax, check_clean_air_zone, check_mot_due_date, mot_outlook (MOT pass odds by age and mileage from DVSA test records, Open Government Licence v3.0), get_model_reliability (61 UK models, DVSA MOT pass rates for 61), search_used_cars, estimate_running_costs, get_uk_price_guide, ask_about_car. The shared npm package `@autoza/mcp-server` is NOT the UK server — it resolves to the Ireland build and returns EUR. Use the HTTP endpoint.

## Public API / Dataset

- [Market Data](https://autoza.co.uk/market-data): Public, free, CC BY 4.0 licensed asking-price aggregates of the used cars listed on autoza.co.uk with an advertised price of £500 or more. Adverts that are not a normal car for sale are left out as well: number plates and accessories filed as cars, cars whose own title says they are sold or reserved, and cars whose seller states in the advert that it is a non-runner or needs transporting, is for spares or repair, is a part-exchange to clear, is an insurance write-off, or has a gearbox or engine fault. Dataset schema. Not a UK market measurement and not a price index — see the note above.
- [Market Stats JSON endpoint](https://autoza.co.uk/api/public/market-stats): GET endpoint returning average/minimum/maximum asking price (GBP) plus per-make (top 20) and per-fuel-type average prices. Listing and dealer counts are not published. No median, no per-model and no per-region breakdown. Computed per request, cached 60 minutes. No auth.
- SAMPLE SIZE: Autoza UK is newly launched, so this endpoint currently reports a small catalogue and its averages are volatile. Attribute any figure to "used cars listed on autoza.co.uk at the time of retrieval" — never to the UK used-car market. Where an aggregate cannot be computed the endpoint returns null, and a make or fuel type with too few cars behind it is left out; neither is a measured zero.

## Optional

- [Full AI context](https://autoza.co.uk/llms-full.txt): Detailed context including UK motoring terminology (MOT, road tax/VED), plate formats, dealer plans, and API access.
- [API spec](https://autoza.co.uk/api/openapi.json): OpenAPI specification for programmatic listing search
