Frequently asked questions.

A visible-condition laboratory. You upload photos. We record what is visible and apply a published formula. We do not take the card, slab it, or authenticate it.

No. We are not affiliated with those companies. The large number is an XGrade assessment. The projected professional range is where a slab house is most likely to land on the physical card. It is not a promise from them.

We do not publish a single accuracy percent. A photo-only system cannot see the physical card. We publish checkpoints, deductions, and hard caps instead. Incomplete photos cannot produce a gem.

Gem 10 requires excellent unsleeved both-side photos, all four corners visible and 10, all subgrades 10, front ≤55/45, back ≤75/25, evidence ≥ 90%, no glare, no sleeve. Any miss caps at 9.5 or lower.

Without a photo of the back of the card, we will not issue above 9.

It scores 7. It is not assumed sharp. Two or more unseen corners cap the report at 8.

Any trading card you can photograph: sports, TCG, vintage or modern. We do not default to a game. We do not use licensed art in samples.

Yes, if you can photograph them without disabling glare. Glare caps at 9. A glare-blind “10” is not an assessment.

Even, diffuse light. Unsleeved. Square to camera. All four corners in frame. See the photograph page.

Usually under a minute after you submit, depending on the vision model. The formula itself is instant.

The website and sample are free. A live inspection uses the xAI vision model and is billed to the operator’s API key (typically a few cents per card). Signed-in users are capped at eight reports per day.

Yes. Issued by {shop} · Assessed by XGrade. Same inspector.

Yes. The ID is the verify URL. Anyone can reopen it. If the photos are not the card being sold, the report does not apply.

Not as a public product yet. The protocol is already documented so another implementation can be checked against it.

If you need an official holder, population, or marketplace convention — yes. Use XGrade first so you are not paying to confirm what the photos already showed.
