Common Errors & Troubleshooting

Weak passwords returned despite settings Some query parameters may not be set correctly or are being ignored.
Double-check the parameter names: len (length), num (include numbers), caps (uppercase), special (special characters) — all are boolean strings.
CORS error in browser Browser security policy may block cross-origin requests depending on the deployment.
Make the API call from your backend server instead of directly from client-side JavaScript.
Slow response or timeout The API may be hosted on a free tier that spins down after inactivity.
Send an initial wake-up request and retry after 5-10 seconds if the first request times out.
