How to use Autotrader endpoints

Crawlora's Autotrader endpoints return vehicle search results, listing detail, and dealer profiles as normalized JSON with one API key — no HTML parsing required. Autotrader's search, vehicle and dealer routes use three different identifiers and inputs, and the documented contract matters more than the example call: make and model take Autotrader's own codes, and a model requires a make.

1. Step 1

   Search vehicle listings

   Send a make, model, and location to /autotrader/search for normalized vehicle summaries — price, year, mileage, colors, and transmission.

2. Step 2

   Get listing detail

   Pass a listing id to /autotrader/vehicle for the full vehicle spec, including drivetrain and fuel type.

3. Step 3

   Look up a dealer

   Pass a dealer id to /autotrader/dealer for the dealer profile plus a first page of current inventory.

4. Step 4

   Monitor over time

   Re-run searches on a schedule to track price, mileage, and inventory changes.

5. Step 5

   Send Autotrader codes for make and model

   make takes Autotrader's code (for example TOYOTA, HONDA or BMW) and model takes a model code such as CAMRY, which requires make. A ZIP must be five digits and radius is in miles, so normalize user input before the call.

6. Step 6

   Take ids from the right URL segment

   The vehicle route takes the numeric segment of a /cars-for-sale/vehicle/{id} URL, and the dealer route takes the numeric segment of a /car-dealers/{id} URL. They are different id spaces, so store which one you hold.

7. Step 7

   Combine the three routes

   Search returns vehicle summaries (make, model, trim, year, mileage, pricing, images) plus a total matching count. The vehicle route adds the full specification, listing description and seller detail, and the dealer route adds a profile and a first page of that dealer's inventory with a total listing count.

8. Step 8

   Expect vehicle pages to 503 on shape drift

   On 2026-10-30 /autotrader/vehicle/788444963 answered 503 autotrader returned a page without a __NEXT_DATA__ payload, while /autotrader/dealer/670936 returned AutoNation Toyota South Austin with rating 5 from 15,166 ratings and 25 inventory rows.
