One car in full, from Cars24's own car-detail endpoint — 79 keys on the car measured. Everything a `search` row carries plus: Cars24's INSPECTION REPORT (`condition`: per-area imperfection count, the source's own OK/WARN/ERROR status, its written note and, where published, the inspector's engine clip) with the defect photographs; the complete spec and feature table as Cars24 groups it (71 rows on the car measured); tyre tread life per wheel; the service-history summary; insurance type and fitness-certificate expiry; the hub it stands at with street address and opening hours; the photo gallery grouped exterior / interior / tyres / defects; Cars24's own buying highlights and promises; and how many people have wishlisted it. 🔴 Measured and published honestly: an OWNER-DIRECT car has no inspection report and no service history — those come back null with a warning naming them, never faked. A dead id returns NOT_FOUND, not an empty success.

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.
