title: Google Places API in iOS application
body: <p>Let me share my findings before asking the question.</p>
  
  <p>Google Places API documentation says:
  "Note: To use the Google Places API you must first request a Maps API
  client ID and cryptographic key which you must use to sign your
  request URLs. For information on signing URL requests, please see the
  URL Authentication documentation within the Web Service APIs home
  page."</p>

  <li><p>The Google Places API is still in developer preview.
  <a href="http://code.google.com/apis/maps/documentation/places/" rel="nofollow noreferrer">http://code.google.com/apis/maps/documentation/places/</a></p></li>
  <li><p>We need a Client ID (required) and a Signature (required) to use
  the Google Places API.

  <li><p>And, to get the Signature, we need a Google Adsense account to get
  Adsense publisher id (required).

  <li><p>The Signup page for Google Maps API suggest that, "Your service
  must be freely accessible to end users. To use Google mapping
  technology in other types of applications, please use Google Maps API
  Premier. See this FAQ for more information."

  <p>Now, here's what i want to know.</p>
  
  <p>I'm planning on using Google Places API in my iOS application. I don't
  want to use Adsense. Can i still access the Google Places API for
  free? How?</p>
  
  <p>If i can't access the Google Places API for free, what are the costs
  associated with using this service, and the available payment models?
  I wasn't able to find any particular resources for this information.</p>
  
  <p>Here's a specific scenario. What if my iOS application is free. The
  free version uses Google Places API. But... my iOS application has
  some additional features which are exposed using In-app Purchase (paid
  features). The paid features do not use Google Places API. Is this
  acceptable?</p>
