title: Commercial usage of wit.ai
body: <p><strong>Some one from wit.ai team please answer this</strong>   </p>
  
  <p>We are planning to use wit.ai for commercial purpose. Is there any usage policy? Please provide some guidelines of Dos and Don'ts. Also, will this service be free in future also or are you planning on launching an enterprise version? </p>
  
  <p>Mainly, what about the API hit rate, in our use case the number of API calls would be around 100K calls per day?</p>
  
  <p>Thank you.</p>
