Introducing the CardGrade API: Automate AI Card Grading at Scale
CardGrade now offers a public REST API for Pro and Business subscribers. Programmatically submit cards for AI grading, retrieve results, and integrate CardGrade into your tools and workflows.
CardGrade Now Has a Public API
We built CardGrade to make AI card grading fast and accessible. Today, we're taking the next step: the CardGrade API is now live for Pro and Business plan subscribers.
Whether you run a card shop, operate a prep service, build inventory tools, or just have a large collection to process, the API lets you integrate AI card grading directly into your workflow — no browser required.
What Can You Do With It?
The CardGrade API is a standard REST API that accepts card images and returns the same detailed grading reports you get on the website:
- Submit cards programmatically — Upload front and back images, specify the grading company standard (PSA, BGS, CGC), and receive a grading ID
- Poll for results — Check the status of a grading and retrieve the full report when it completes
- Access your grading history — List past gradings with filtering and pagination
- Check account status — View your current plan, credit balance, and rate limits
Every API call uses the same CGI Vision AI engine that powers the website and Chrome Extension, so you get the same 92.8% accuracy and full 47-point inspection report.
Who Is This For?
The API opens up use cases that weren't practical through the website alone:
Card shops and prep services can pre-screen inventory in bulk before deciding which cards to send to PSA, BGS, or CGC. Upload photos as part of your intake process and get grade predictions without manual effort.
App developers and tool builders can integrate CardGrade grading into their own platforms — inventory management systems, marketplace apps, collection trackers, or anything else that touches trading cards.
