I need to get the usage per device using rest api. Where do I find info regarding this rest api?  
For example, I can get message count for a company using the api  
[https://octave-api.sierrawireless.io/v5.0/eaton/usage/messages/?gte=now%2FM](https://octave-api.sierrawireless.io/v5.0/eaton/usage/messages/?gte=now%2FM)  
I have many devices under this company. Is there a filter that I can apply to get messages by device?

Hello,

This API is not documented as it is not meant to be integrated from customer/3rd party platforms. We do allow some usage of this API given specific fair-use rules, which has been the case with the company you work for (API details and fair-use rules have been shared).

I suggest you to bring the topic through your technical/project management to close the loop or reach out to us if needed
