How this service works

TCG card grading, conformal risk forecasting, and market intelligence. Powered by x402 micropayments — USDC on Base, USDC on Solana, or USDG on Robinhood Chain; the 402 offers all three and the agent picks a leg. Free tools require no payment. Paid tools return HTTP 402 — sign a payment and retry with the payment proof header.

Output

Returns predicted PSA and Beckett numerical grade estimates for the submitted card image, along with a condition assessment and confidence score based on AI vision analysis of the card's surface, corners, edges, and centering.

Example use cases

Example prompt

“Can you predict what PSA and Beckett grades this Pokémon Charizard card would get? Here's the image URL of the card front and back.”
