**Impact:** Users cannot sign up through the website interface  

**Details:**

**Workaround:** Direct API call works fine: `POST /v1/signup/free`

## Summary
**1 Critical Issue:** Browser signup form hangs (while API signup works)  
**12 Security Tests:** ALL PASSED  
**Core Functionality:** API works perfectly  
**Documentation Quality:** Excellent, comprehensive examples

## Recommendation
**URGENT:** Fix the browser signup form JavaScript issue. The backend works fine, so this is likely a frontend form submission or error handling bug preventing the API key from displaying after successful creation.
