Troubleshooting

"API key is required"

Add your API key in the input

"API error 403" or "Unauthorized"

Your API key is invalid, expired, or doesn't have access to this specific API endpoint. Double-check your key and account permissions.

"API error 429" or "Rate limit"

Too many requests. Wait a minute and try again, or reduce the number of items per run.

No results or empty dataset

Check the run log for error messages. Common causes:

Invalid input format (check the examples above)
API key without proper permissions
The target data doesn't exist or is too small to track

How do I test without an API key?
