Search Dongchedi's live used-car inventory (懂车帝二手车). Filter by city, brand, series, price band, registration year, mileage, fuel, gearbox, vehicle type, size class, displacement, drivetrain, emission standard, origin, inspection report, then sort and page. Each row has price in CNY (and 万), new-car price, mileage in km, first-registration year, the car's city, transfer count, dealer id, photo and tags. Dongchedi's own `total` stops counting at 10 000 (`total_capped: true`), and paging stops at page × limit = 10 000 — narrow the filter to go deeper. There is no free-text keyword search on Dongchedi's used-car API: use `brand_id`/`series_id` (from `brands`/`series`).
City to search, as Dongchedi names it in Chinese ('北京', '上海', '成都'); common pinyin/English names ('beijing', 'shanghai') are mapped. Default '全国' = nationwide. Call `cities` for the full list (371).

ReefAPI is one HTTP gateway to 632 live web-data APIs covering 3860 endpoints across 13 categories. Every endpoint answers with the same JSON envelope, so one integration reaches all of them. Each response reports what it cost and when the source was read.
No signup, no API key and no card are required to try an endpoint on this page. Anonymous calls run on a shared demo key, capped at 15 calls per hour per visitor. Pick an API, fill the parameters and the real response comes back from the live source, not from a canned sample. A free account lifts the cap and gives you 1,000 credits and your own key.
Browse every API in the catalog, read an endpoint's fields and example response in the docs, or see per-call credit costs on the pricing page.
