The filter values Good Games offers for one game's singles or sealed product or for a collection, with product counts: rarity, finish, card type, stage, HP, weakness, ink, colour and more.

Working example
Parameters

Limit to one game. Singles exist for pokemon, mtg, lorcana, one-piece, flesh-and-blood and riftbound; yu-gi-oh, digimon and star-wars-unlimited are sealed product only. Omit it to search the whole store.

With game: individual cards (default) or the game's sealed product.

A collection handle or numeric id, instead of game (the `collections` action lists all 760+).

What you can run here, without an account

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.
