If you can describe the cars you want to find, there is a parameter for it. [Read the technical docs →](https://docs.marketcheck.com/uk/docs/api/cars/inventory/inventory-search) ## Filter by more than 120 criteria Every field you would expect, and many you would not. A few of the highlights: ### The car itself Year, make, model, variant, body type, doors, transmission, fuel type, engine size, colour, even ULEZ compliance and insurance group. ### Price and value Price bands, price changes and discounts, VAT status, and mileage ranges, so you can find the cars priced out of line with the market. ### Location Radius search from any postcode or coordinates, or filter by city, county or country. Results come back nearest-first with the distance on every car. ### The seller Search within one dealer, a dealership group, franchise vs independent, or FCA-authorised dealers only. Include or exclude any source you choose. ### Market timing Days on market, cars first listed in the last 24 hours, recent price drops. Catch stock the moment it moves. ### Vehicle history Look up any car by its number plate, find its duplicates across sites, or pull comparable cars matched on year, make, model and variant. ## Analytics built into every query The same endpoint aggregates as it searches, so one request answers questions that would otherwise need a data warehouse. ### Statistics Mean, median, percentiles and spread for price, mileage and days-on-market across any result set. Price a car against its real market in one call. ### Facets Count listings by any of 40+ fields: how many of each variant, fuel type or colour exist in a region, with no need to page through results. ### Distributions Band any numeric field, price in £10,000 steps, mileage in 10,000-mile steps, and get the count in each band for instant charts. ## From sign-up to first result in minutes 1 ### Get a key Sign up for a free trial and receive an API key with 500 free calls.

Listings refresh daily across all 11,000 dealers, and you can filter specifically for cars first listed in the last 24 hours, so new stock is searchable the day it appears. ### Can I search by number plate? Yes. Pass a VRM to find that exact car, add nodedup to see its adverts across every website, or use the match parameter to pull comparable cars matched on year, make, model and variant, the foundation of a pricing tool. ### How does location search work? Give the API a postcode or coordinates plus a radius in miles. Results return nearest-first with the distance on every car, and combine freely with any other filter. ### How many results can I retrieve? Up to 50 per call with pagination to 10,000 results per query. For whole-market extraction the same data ships as bulk feeds, which is the right tool beyond roughly that scale. ### What is the auto-complete endpoint? A companion API that powers search-as-you-type: give it a partial word and a field such as make or model and it returns suggestions with live inventory counts, filtered by any context you set, like county or fuel type. ## What our clients say Working with MarketCheck has been a pleasure.
