Frequently Asked Questions
How does the AI grading work?
AgentGrail analyzes the front and back images of each eBay listing using a trained image classifier. It scores surface condition, centering, corners, and edges — then outputs a BUY, REVIEW, or PASS recommendation with a confidence score. It's designed to identify raw cards likely to grade PSA 8 or higher.
How accurate is the AI?
The classifier was trained on thousands of graded card images across PSA 8, 9, and 10 outcomes. It performs best on standard sports cards (baseball, basketball, football). Accuracy varies by card condition and image quality — always review BUY recommendations before purchasing.
What is a scan, and what happens when they run out?
One scan = one AI analysis of a single card image. Each eBay search result uses one scan when classified. When your monthly quota is reached, you can still search and browse — you just won't get AI scores until the next billing cycle or you upgrade.
Which sports and card types does it support?
The classifier has been trained primarily on baseball, basketball, and football cards. Pokemon and other TCGs have been tested with generally good results. Performance is strongest on standard rectangular cards with clean, well-lit photos — heavily stylized, foil, or very low-resolution images may reduce accuracy. Always review BUY recommendations before purchasing.
Is my eBay data private?
Yes. We use eBay OAuth — you authorize read access only and we never see or store your eBay password. Your collection, P&L, and search data are private to your account and are not sold or shared with third parties.
Can I cancel anytime?
Absolutely. Paid plans are month-to-month with no contracts. Cancel from your account page at any time and you won't be charged again. You'll keep access until the end of your billing period.
