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.

post/bestprice/v1/category2 credits
Browse one category's grid without a keyword. Same rows as `search`. Take the category id from a search row's `category_id` or from a category URL.
Working example
Parameters
Numeric category id (806), or a bestprice.gr category URL.
Optional keyword to narrow the category.
1-based page of the grid (16 products a page, measured 2026-10-13). BestPrice currently serves only page 1 to us; a deeper page answers with no rows and page_available=false. (1–)
Rows to return from the page (1-24). The source serves 24 a page; use `page` for more. (1–24)
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.
