# Check Class Code

`POST /public/check-class-code`

## Request

- Base URL: `https://api.excellence-ai.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.excellence-ai.com/public/check-class-code`
- Auth: none declared

Whether a class code names a class a student can still join, and nothing
else: no class, teacher or roster details, no reason for a refusal. What the
signup form asks before an under-15 sends its code (EXC-1454); `/register`
runs the same rule again, so the answer here is a courtesy, not the gate.
