AgentGrail is an AI-powered sports card intelligence platform that analyzes eBay listings — front and back — using computer vision to identify exactly what a card is, score its physical condition, estimate its grading expected value, and deliver an instant BUY, PASS, or REVIEW recommendation with a confidence score and fully auditable reasoning.

Built for card dealers, flippers, and virtual assistants operating at volume, it replaces five disconnected tools with one workflow — compressing card identification, parallel and variant detection, sub-grade analysis, live market valuation, and P&L tracking into a single decision delivered in seconds.

And it never stops working — scanning eBay autonomously every 15 minutes, firing deal alerts the moment a card matching a user's criteria surfaces, even while they sleep.
