Usage Limits
The number of requests you can make is determined by your API license. The ability to track your API usage is a feature that will soon be added to MixRank, but in the meantime, we will notify you at the start of the new month if you exceeded the limits for the previous month.
Your API license also determines what parts of the API are accessible; everything isn't available by default. Let us know if you have any questions about what you can and can't access.
