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.
Keyword search on one country's storefront. Returns the storefront's own result total plus the filtered total so a filter's effect is visible.
What to search for.
Which national storefront to price against. Prices, availability and even the number of matching products differ per storefront.
1-based page. (1–100)
Products per page. iHerb serves at most 48. (1–48)
Result order. NOTE: iHerb's sorted result set is SMALLER than its unsorted one (measured 14807 -> 10559 for the same keyword), so sorting changes which products you see, not just their order.
iHerb's star BAND, 1-5. This is a band, NOT a minimum: measured on one storefront, band 5 returns products rated about 4.8 and up, band 4 about 3.8-4.7, band 3 about 2.8-3.7. Asking for 3 therefore EXCLUDES 4- and 5-star products. The `filters` action prints how many products sit in each band. (1–5)
iHerb brand codes, e.g. NOW. Discover them with the `filters` action.
iHerb category ids; see the `filters` action.
iHerb price-band ids (they are bands, not amounts; the band's boundaries are in that storefront's own currency).
Health-topic ids, e.g. Immune Support; see the `filters` action.
Attribute value ids — diet/certification/form/age; see `filters`.
Programme ids, e.g. iTested.

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.
