Is there a list of API error codes?

Below are the various HTML responses you may receive when using Similarweb's REST API.

Code	Description	Notes
200	Valid response / no error
403	Invalid API Key or out of hits
401	Data not found	This can be for a faulty domain (fsdfsdfdsf.com), or for an incorrectly entered domain (CNN.COM, cnn.com/sports)
101	Dates not in range	Either pulling historical data prior to your allowed package’s range, or pulling future data. The error response message indicates the dates available
102	Granularity not supported
103	Country not available	If your package only supports US and you try to pull DE you will receive this error
429	Too many requests made in a short period of time	This can happen if you make more than 10 requests per second

If you receive any of the above error codes, or a 0 value back from running any API endpoint, your account will not be charged any API hits.
