How this service works
Grade any physical Pokémon, Magic: The Gathering, Yu-Gi-Oh, or Digimon trading card using a 3-stage AI pipeline: (1) Qwen Vision LLM analyzes corners, edges, and surface defects, (2) OpenCV measures exact centering ratios programmatically, (3) BGS professional capping algorithm adjusts the final grade. Returns PSA/Beckett-calibrated subgrades and an overall condition score. Accepts card image URLs or base64.
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.”
