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.
In short: The CardGrade REST API lets card shops, prep services, and developers submit card images programmatically and receive the same 16-zone AI grading reports available on the website — same 92.8% accuracy, no browser required. See the API docs and current plan details for integration guidance.
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.
