SlabX

Verify

Check any cert against its grader.

Pick the grader on the label, enter the cert, and SlabX looks it up where the grader publishes a registry. Where it does not, you record the label and the item stays marked as unverified until it can be checked. A badge means what it says.

Graders

Six graders, one Verify screen

Cert formats and what SlabX can do for each today. Nothing here is a plan.

SlabX never scrapes a grader's website. Registry data comes through each grader's published API, and everything else is recorded from the label you hold.

Badges

Graded, verified, or from the label. Never mixed up.

Three states, three looks, so a buyer or a family member can tell at a glance what has been checked.

  • Grade badge

    The grader and grade, in gold, on every graded item. It comes from the registry when the grader publishes one, or from the label you recorded.

  • Verified mark

    Added to the badge only after a registry lookup confirms the cert. Until then the item reads "unverified" on its screen, so nobody mistakes a label entry for a checked one.

  • Condition chip

    Raw cards carry the condition you set, and a quantity chip when you own more than one.

Every verification is a line in the item's history, stamped with the grader and the cert, so the badge travels with the item.

The Collection screen: a Charizard with a gold PSA 9 grade badge, Blastoise with a quantity chip and Lightly Played condition, and the PSA verified filter chip
