Search Cars24's Indian used-car catalogue — both its own refurbished stock and the owner-direct cars on the same platform. 30,170 cars across 184 cities on 2026-10-01, counted from the source's own facet endpoint. Returns the car, its price in rupees, odometer, year, variant, colour, seats, owner count, masked RTO plate, body/fuel/gearbox, where it physically stands (locality + coordinates), the canonical cars24.com URL, the photo count, when it was first listed, the seller kind and Cars24's own finance estimate. Every filter below was measured against the count the source itself published for that value in the same run. 🔴 Two honesty notes you should plan for: the source caps `total_available` at 10,000 (so an all-India query returns `total_is_capped: true` and you should read the real population from `filters`), and one page is at most 30 rows — walk further with `cursor`, which was measured to have zero overlap and to reach 100 % of a city's published total.

What you can run here, without an account
ReefAPI is one HTTP gateway to 438 live web-data APIs covering 2778 endpoints across 14 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.
