# Troubleshooting

If you run into any issues, here are some common problems and solutions:

* **"Rate limit exceeded"**: Wait for a few seconds and try again. Consider upgrading your plan for more requests.
* **"Invalid email format"**: Make sure the email you're sending is in a valid format (e.g., `user@example.com`).
* **"Unauthorized"**: Ensure your API key is correct and included in the request header.
