Reef AI: ask for any data. Try it
The playground

Try any of 3860 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.

Walk the used trading-card market: every card with a live listing, filtered by brand and category, newest first or in the source's own order. Use it to build a catalogue without a keyword.

Working example
Parameters

Brand slug ('pokemon', 'one-piece', 'yu-gi-oh'). Omit for all.

Category id from brand/detail. Omit for all categories.

1-based page number. (1–)

Rows per page (1-100). The source refuses more than 100. (1–100)

`latest` for newest first, anything else for the source's own order. Measured: these are the only two orders the source actually applies.

Only listings that are still for sale. Default false, which also returns recently sold ones (each carries `is_sold`).

What you can run here, without an account

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.
