AgentGrail is live and built by two collectors who got tired of guessing.

Finding the right raw card to grade used to take hours. AgentGrail compresses it into seconds. We built AgentGrail for the collectors, dealers, and virtual assistants who live in eBay listings — people making real buying decisions under time pressure, where a misidentified parallel or a missed centering flaw is a real financial mistake. Our AI scans eBay listings front-and-back and returns a BUY, PASS, or REVIEW recommendation — with a confidence score, grading EV breakdown, and the reasoning behind every call. No black box. Every decision is auditable. What AgentGrail does: → Identify cards by set, year, parallel, and variant — not just player name → Estimate PSA grading probability across subgrades (centering, corners, edges, surface) → Surface deals worth acting on before they're gone → Track P&L with fee-aware calculations against live eBay comps → Alert your watchlist when prices move → Run autonomous Buying Agents that scan eBay every 15 minutes on your behalf Built for high-volume operators and passionate hobbyists alike. Priced from $9/month — and free to try with no credit card required. Check us out at agentgrail.ai.
