Try any of 2778 endpoints — live.
Pick an endpoint, load a working example, tweak the params, and send — no signup to try. Results render the way the data deserves; raw JSON, headers & code are one tab away.
selency's own category tree — 9 roots, 65 second-level and 126 third-level nodes — with each node's French and English name AND slug side by side, its parent, its examples text and its image. This is where the `category` parameter's values come from, and why that parameter never has to be guessed: the source answers an unknown category value with HTTP 200 and zero rows rather than an error.

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.
