TRANSPARENT MARKET INTELLIGENCE
The market. Without the guesswork.
Evidence-based trading card valuation uses completed sales—not asking prices or AI-invented numbers.
Market data is not connected yet.
AI identification and personal inventory are active. Automatic market prices require an authorized completed-sales source. Until then, unknown values stay unknown. You can import your own real sale evidence on any saved card.

eBay
eBay’s Marketplace Insights completed-sales API is restricted and not open to new users. Browse returns active listings, not reliable completed-sale prices.
An authorized provider or existing approved eBay access is needed.
Vinted
Vinted Pro Integrations is limited to allowlisted Pro businesses, not a general public completed-sales feed. No authorized Vinted sales integration is configured for this app.
Use evidence from your completed transactions; do not treat a sold listing label as proof of final price.
Your sale evidence
Import real completed-sale records with the USD sold amount, date, exact card identity, condition, grade, and evidence URL.
Always labeled user-supplied. Imports are not independently verified.
How a price estimate is calculated
- 01
Match the exact card
Brand, set, year, card number, subject, printing variant, language, market condition, and actual grade must match. A tentative AI grade never substitutes for a certified grade.
- 02
Use recent completed sales
Only matching USD sales dated within the last 90 days are eligible. Duplicate evidence URLs and dates are ignored. No asking prices or currency assumptions.
- 03
Show the evidence and uncertainty
The central estimate is the median. The displayed range is the 25th–75th percentile, not a prediction interval. Unknown identity fields cannot match. Sparse or user-supplied records have limited confidence.
- 04
Keep the history
Every eligible evidence import saves a dated valuation with its supporting sale IDs. Card details, photographs, cost, and history are saved to your private account.
Updates from imported evidence
Import new completed-sale evidence on a saved card to recalculate its estimate from matching sales within the last 90 days. Eligible imports save a dated valuation and its supporting sale IDs to your account.
This app does not fetch new marketplace sales or refresh prices in the background. Imported records remain labeled user-supplied, and cards without eligible evidence remain unvalued.
Questions collectors ask
Can AI tell me a card’s price?
AI is used only for identification and visible-condition inspection here. It cannot verify market sales or safely generate a current price.
Is my potential grade guaranteed?
No. Lighting, resolution, hidden defects, and physical inspection matter. AI estimates are tentative opinions and never grading certificates.
Are my uploaded card images private?
No. The image storage is public. Your inventory records and purchase prices are account-private; avoid uploading personal or sensitive information.
Why is a card’s value blank?
There is no matching completed-sale evidence yet. Blank is more accurate than a made-up price.
