post/gemrate/v1/set_pop4 credits

A set's population report from one grader (PSA, BGS, SGC or CGC): every card and parallel with total graded, gems, gem rate and the count at each grade. PSA rows add graded past month and prior month, 30-day gem rate and momentum, the last-year weekly trend, last gem date and a recent cert number. Filter by player/character name, sort, paginate.

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.
