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.
Search Coolblue by keyword: product id, name, price in euro, the delivery promise the site prints beside the product, the review score and the key specs. When the keyword is a whole category Coolblue answers with that category instead of a result list — this endpoint follows that and tells you so in `resolved_as`, so a search for 'headphones' returns headphones rather than an error. `total` is Coolblue's own match count and is present on keyword result sets.
What to search for, in English or Dutch. A product number (979101) or a manufacturer code (EP2-61329) also resolves to the single matching product.
Which storefront to ask. Prices and stock genuinely differ between them (measured: 5 of 7 shared products had a different price on nl vs be) and each market lists products the others do not.
Facet segments in 'key:value' form, for example 'merk:apple'. One value per key (the source answers a multi-value '+' form with 404). Call the 'filters' action to list what a category accepts, with the result count behind each value.
Result order. All five were measured to genuinely reorder the grid. An unknown value is rejected rather than passed on, because the source accepts any string and silently ignores what it does not know.
Page of results. Coolblue stops a keyword result set at page 20: page 21 returns HTTP 404, so at most 480 products of a larger set are reachable and `results_reachable` reports it. Narrow with `filters` to reach the rest. (1–20)

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.
