Any way to check API rate limit?

Is there any way to check how many API requests our API key has made to a specific end point to determine how close we are to hitting the limit?

For example, the Purge Files by Cache-Tags or Host says:

NB: Cache-Tag and host purging each have a rate limit of 30,000 purge API calls in every 24 hour period. You may purge up to 30 tags or hosts in one API call. This rate limit can be raised for customers who need to purge at higher volume.

Is there some way to see how close we are to hitting the 30,000 purge API call limit?

Thanks
