title: Twilio API request limit / throttle?
body: <p>I have a c# service which runs through a list of clients , for each client a number search is performed and if successful a number purchased.</p>
  
  <p>The service works successfully however I have noticed that it seems to stop randomly when calling the Twilio API.</p>
  
  <p>Is there any form of throttling or request limiting per account?</p>
  
  <p>For our initial import of clients we have 1000 odd records and it seems to stop about 350 records in.</p>
  
  <p>Thanks,</p>
