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.
Every seller offer for one product — the price comparison itself. One row per merchant: seller name, Empik shop id, shop page, super-seller flag, seller rating and how many ratings it rests on, the price actually charged and the list price, whether the discount needs an Empik membership, the item condition (new, used as-new/good/acceptable, damaged packaging), declared dispatch window and the delivery line. Rows keep Empik's own ordering; `cheapest` is computed separately because that ordering is NOT purely by price.
Empik product id — the code in the product URL (…/ostatnie-zyczenie…,p1102239921,ksiazka-p → p1102239921). A full product URL is also accepted. Empik uses three id shapes and all work: 'p1102239921', 'prod58904739' and a bare legacy number like '7291'. Every `search` row returns `product_id`.
Advanced: how many times to retry a difficult request (1-8, default 4 — leave unchanged for typical use). (1–8)

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.
