API Call Samples

We reserve the right to log and verify your API calls and to contact you if we detect abuse on your part. For example:
  • the requests takes too long to return
  • the requests return too much data at a time
  • The requests are too frequent
We strongly suggest using the date filter parameters to return only the data that is relevant.
