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/kanabell/v1/card1 credit
One Ka-nabell card product in full: price and stock per condition grade, last price changes, sales in the last 7 / 30 days, the buy-back price with the shop's per-condition rate table and how many it still wants, the card's text and stats, images — plus the same card in the shop's other sets, rarities and PSA slabs with their prices.
Working example
Parameters
A Ka-nabell product id (a row's `id`, a UUID) or a ka-nabell.com card URL (/ec/sell/<game>/single/<id> or /ec/buy/<game>/single/<id>).
Optional: the game, when you know it (the id alone is enough).
Also list the same card in the shop's other sets / rarities / slabs (the site's 同名カードをさがす), with their prices — one more backend query.
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.
