AutoTrader UK Data Parser & API
AutoTrader UK is Britain’s #1 car marketplace — around 86.3M visits in January 2026 and 400K-450K vehicles — and Carapis extracts its full listing data, including its authoritative price-position indicators, through one REST API. The LSE-listed portal is so central to the UK market that its used-car prices feed the ONS inflation basket, and Carapis serves its data without you maintaining a bot-managed scraper.

What is AutoTrader UK?
AutoTrader UK is the dominant car marketplace in the United Kingdom, an LSE-listed company that connects buyers with roughly 400K-450K vehicles from dealers and private sellers. It is best known for its price-position intelligence — each listing is rated against the market — and its data is authoritative enough that the Office for National Statistics uses AutoTrader used-car prices in the UK inflation basket. The site sees ~982M visits per year, peaking at 86.3M in January 2026.
Market Position
AutoTrader UK is the clear #1 in Britain with ~80M+ visits/mo (86.3M in Jan 2026) and 400K-450K live vehicles. Its scale and price authority give it a unique position: it both runs the largest UK marketplace and publishes the market-intelligence indices the rest of the industry references. That price-position data — Good/Fair value ratings derived across the whole market — is a resellable analytics signal on top of the raw listings, making AutoTrader one of the highest-value sources Carapis covers in Western Europe.
What the API returns
Response schema
Indicative — this is the shape, not a guarantee. Every source returns the same structure, so what you build against does not change when you add one. Which fields carry a value depends on the source and on the individual listing: a site that does not publish mileage returns null there, and AutoTrader UK is no exception.
List — GET /apix/api/vehicles/ — returns 30 fields per vehicle:
