Scan API pricing

Simple plans. Hard quotas.

Only successful scans count. Rate-limited calls and scans that never completed are free, and nothing ever bills past your plan. Every tier gets the same engine at the same measured accuracy: 60,000+ EN and JP printings, graded slabs, foil and pattern variants.

Every paid plan is a monthly subscription that renews automatically, at the price shown above, charged to your card through Stripe until you cancel. There is no contract and no minimum term. Cancel yourself in the billing portal, linked from your keys dashboard: cancelling stops the next charge and leaves the period you already paid for intact. Unused scans do not roll over, and there are no overage charges. Read the Billing Terms and the API Terms.

Metered honestly. A 429 and a scan that never completed do not touch your quota. A completed scan bills one unit, including when the photo turns out to be a card back or sealed product and no card comes back.
No overage bills. At your cap the API returns 402 with an upgrade link. It never silently charges.
Accuracy in public. 155 of 159 real marketplace listing photos identified correctly, measured September 19, 2026 over consecutive production runs of a fixed benchmark (range 154 to 157), and the same gate runs at least twice before any engine change ships. See the method.
