The marketplace's own category tree with live per-category listing counts: the 45 top-level sectors (metalworking & machine tools, woodworking, construction plant, forklifts, food technology, packaging, agricultural…) with the numeric ids every other action's `category_id` takes. Pass a `category_id` to drill into that sector's sub-categories, which is how you get from 7,593 construction machines to the 803 excavators or the 2,049 access platforms. Every count is the source's own live figure, not an estimate.

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.
