Search CardTrader for one game by card or product name: product id, name, version, collector number, set, category, number of offers, the lowest price and the image. Narrow to a set, a category (singles, booster boxes…) or a rarity; sort by name, price, collector number, rarity or release date; page through 12 rows at a time. Add card_language / min_condition / foil / first_edition to get, per row, the 3 cheapest offers matching them (CardTrader's own search filter), and rows without a matching offer dropped.
Card or product name (part of it is enough), or text of the version line such as a collector number '081/080'.
The game, as CardTrader names it in its URLs. Aliases like mtg, ygo, onepiece, fab, swu, dbs and the numeric game id are accepted.
Set slug from `expansions` (e.g. delta-reign, wild-blaze) or a cardtrader.com set URL.
Category: singles, or a category id / slug / name from `games` (Booster Box, Boosters, Bundle, Complete Set…). Omit for every category.
Rarity as CardTrader names it for the game (rarity_options in the response lists them). Applies to single cards; category defaults to singles when only rarity is set.
CardTrader's own orderings: name, price, collector number, rarity, release date.
Result page, 12 rows each (CardTrader's page size). (1–500)
Only products that currently have offers.
Only offers of cards printed in these languages (one or more codes, e.g. en or en,jp). Names such as Japanese are accepted.
Only offers in this condition or better (Mint > Near Mint > Slightly Played > Moderately Played > Played > Poor). Codes NM, SP, MP, PL, PO are accepted.
true = only foil offers, false = only non-foil (games with a foil property; for Pokémon use reverse_holo).
Pokémon: true = only reverse-holo offers, false = only non-reverse.
true/false: first-edition copies (Pokémon, Yu-Gi-Oh!).
true/false: signed copies.
true/false: altered copies.
Also return the 3 cheapest offers of every row (set automatically when an offer filter is given).
CardTrader site language: card names follow it in translated_name (Charizard → Glurak in de); a query also matches names in this language.
Price currency. USD prices are CardTrader's own USD prices (with its own buyer fee), not a conversion of the euro price.
Ship-to country of the shopper. CardTrader shows only the offers whose sellers ship to this country (directly or through CardTrader Zero), and the shipping 'from' price to it, so offers and lowest prices differ by country.
How many fresh exits to try before giving up. (1–5)

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.
