The source's own filter values with its own counts, for any scope you can search — the whole catalogue, a category, a free-text query, or any combination of the search filters. Use it to discover the 200+ filterable designer names, the 94 French departments, the 51 materials or the price range inside a category before you search. ⚠️ The counts are selency's own counters and they are exact only while the set is small: measured against the number of rows the same filter actually returns, they agreed to the row on 19 of 26 country filters (up to 7,248 rows) and then drifted by up to 13.5% above roughly 10,000 — so treat a large count as 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.
