Set up monitoring of imgur API

[AlexBurkey]

This SHOULD be fine but I don't want to have issues.

https://apidocs.imgur.com/?version=latest#rate-limits

The Imgur API uses a credit allocation system to ensure fair distribution of capacity. Each application can allow approximately 1,250 uploads per day or approximately 12,500 requests per day. If the daily limit is hit five times in a month, then the app will be blocked for the rest of the month. The remaining credit limit will be shown with each requests response in the X-RateLimit-ClientRemaining HTTP header.
