Get_sensor_history

API calls to this endpoint (get_sensor_history) have been restricted. Please try again later or contact PurpleAir for more information.

Is it an error on my end? I have an old API key. Do I need a new API key to get access?

Thanks!

For now, you need to request access to that endpoint, as documented in this post:
