Graded Card Auction Prices API (Goldin, Fanatics Collect, Pristine Auction, MySlabs)

CompSniper has four endpoints for realized prices from the big graded card and collectibles auction houses:

All four use the same API key, per-minute limit, monthly allowance and purchased credits as the eBay endpoints, on every plan including free. No auction-house account is needed. Every call is one keyword search and counts as one request; failed calls are never charged.

price is what the buyer paid in US dollars. Where the house charges a buyer's premium (Goldin, Fanatics Collect auctions, MySlabs) it is included, so prices compare directly with eBay sold prices.

Request

curl --fail-with-body \
  -H "Authorization: Bearer cs_live_REPLACEWITHYOURKEY" \
  "https://api.compsniper.com/v1/goldin/sold?keyword=1999+pokemon+base+set+charizard+psa+8"

import requests

for house in ["goldin", "fanatics", "pristine", "myslabs"]:
    response = requests.get(
        f"https://api.compsniper.com/v1/{house}/sold",
        headers={"Authorization": "Bearer cs_live_REPLACEWITHYOURKEY"},
        params={"keyword": "michael jordan 1986 fleer psa 8"},
        timeout=60,
    )
    response.raise_for_status()
    data = response.json()
    print(house, data["totalItems"], "sales, median", (data["summary"] or {}).get("median"))

Parameters

Page sizes: 50 sales (Goldin, Fanatics Collect), 60 (Pristine Auction), up to 72 (MySlabs). Keep requesting the next page while hasNextPage is true.

MySlabs returns one page per search. Add deep=true to merge the results of every sort order and price range for the same keyword (a few hundred distinct sales, about 10 seconds). Deep MySlabs calls count as one request each and are limited to about 3 per minute per account.

Fields

The houses match keywords loosely, the way their own search boxes do: the search above also returns other Charizard cards and grades, which is why its price range is wide. Check title, grade and year (or add the set, number and grade to the keyword) before you use a price as a comp for one exact card.

totalResults is how many sales match the search when the house reports it. summary holds the count, median, mean, min, max, p25 and p75 of the returned prices.

Coverage

Billing

• One successful call is one request on every endpoint, including MySlabs with deep=true.
• Failed requests are free.
• Repeat calls can return instantly from a short-lived saved copy and count as one request.

Errors

These endpoints use the shared error format (code, error, requestId):

See Errors for the full list. For PSA population reports and PSA's own sales records by grade, see the PSA endpoints.
