Card Labo's buy-back list (買取): what the shop pays for each card and how many it still wants, by name or card number, game, category or curated list, highest price first if you like.
Card name or card number as the shop writes it, in Japanese or kana (リザードン, りざーどん); several words narrow it (リザードン SAR); a card number such as IMPH-JP018 or 110/080 also matches. English names do not match: titles are Japanese.
Limit to one game (also accepted: ポケカ, 遊戯王, ワンピ, デュエマ, ygo, op, dm). Most games are scoped by their own category; Pokémon, Yu-Gi-Oh!, Weiß Schwarz, Vanguard and Battle Spirits span several, so there the rows are checked and meta.total can be an estimate. For sealed product use category_id.
One shop category (a game series, set or rarity list); the `categories` action lists them. Ids differ between the shop and the buy-back site. On the buy-back site it cannot be combined with keyword.
One curated list (特価コーナー, PSA/PCG graded ...); the `categories` action lists them under groups. On the buy-back site it cannot be combined with keyword.
Order of the rows.
Page number; meta.last_page says how many there are. (1–100000)
Rows per page: 60 or 120, the two sizes the shop has. (60–120)

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.
