Ace Grading Certificate Checker

1. 1

   Find the certificate number

   It is printed on the Ace Grading label on the slab. Use the digits only.

2. 2

   Enter it and press Check

   No account is needed. The free checker allows 10 lookups a day, and most answers arrive within a second or two.

3. 3

   Compare the record with the slab

   The card, set, card number, grade and subgrades on the record should all match the label. Where photos are on record, compare them with the slab in your hand.

What an ACE certificate lookup returns

The checker and the API return the same record: the one published on the Ace Grading certificate page. Any field can be empty when the page does not show it, and older certificates often have fewer photos.

Population counts are captured when the record is retrieved and can lag the live Ace Grading page. The lookup does not return graded-card prices or sales.

Ace Grading cert lookup API

One GET request returns the record as JSON. Send your key in the x-api-key header and keep it on your server. New accounts include 100 free credits; after that the endpoint is part of the Business plan and above, and each call counts toward the plan allowance.

Request

// Node 18 or later, run on your server.
const cert = '1471772';
const response = await fetch('https://api.tcgapis.com/api/v1/ace/' + cert, {
  headers: { 'x-api-key': process.env.TCGAPIS_KEY }
});
const body = await response.json();
if (response.status === 404) console.log('No certificate with that number');
else if (!response.ok) throw new Error(body.error || 'Lookup failed: ' + response.status);
else console.log(body.certificate.subject, body.certificate.grade, body.certificate.subgrades);
