post/cgc/v1/cert_lookup2 credits
Verify a CGC-graded card by its certification number (the number on the slab label): card name or player, game, set, card number, year, language, variants, rarity, attributes, grade as printed (e.g. PRISTINE 10, GEM MINT 10, 9, AUTHENTIC) with CGC's grade name and number, autograph grade, sub-grades when the label carries them, grade date, front/back slab images, and that card's population (how many CGC graded at this grade and above, full grade breakdown). An unknown cert returns NOT_FOUND (not charged).
Working example

CGC Cards certification number (10-13 digits) or a cgccards.com certlookup URL.

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.
