Are the Cloud Vision API limits in documentation correct?
<p>I cross posted this to the google group for Cloud Vision...
and have added some additional findings.</p>

<p>Here are all of the specifics I believe are relevant:</p>

<ul>
<li>Using VB.NET 2010</li>
<li>Using service account authentication</li>
<li>Limited to .NET 4.0</li>
<li>Using these Google libs: Google.Api  v1.10.0, Google.Apis.Auth v1.10.0, Google.Apis.Vision.v1  v1.12.0.45</li>
<li>Performing Text and Safe Search Analysis </li>
<li>Passing image content in request (not using Google Drive)</li>
</ul>

<p>When just sending through 4 images or so per request, things work as expected... I get responses, and annotations. </p>

<p>If I up the number of images to 8 files per request,   The response back from Execute contains no results..  No errors, no exceptions either.  </p>

<p>Just a Google.Apis.Vision.v1.Data.BatchAnnotateImagesResponse object with zero responses.   Using a network traffic monitoring tool, I see the connection to google vision - and the service returns a 200 server response.  But is otherwise empty.</p>

<p>Further research showed that I'm able to successfully send about a total 1MB of base64 content to the API per overall request  Anything more, I get the odd condition described.</p>

<p>According to the API documentation, the following limits apply to Google Cloud Vision API usage.</p>

<p>I'm not seeing any way I could be breaking the documented limits:    8 files per each request, total way less than 8MB, and no file even close to 4MB.</p>

<p>Any thoughts as to what I might be missing?  Are the documented limitations below correct?</p>

<ul>
<li>MB per image 4 MB </li>
<li>MB per request 8 MB </li>
<li>Requests per second 10 </li>
<li>Requests per feature per day 700,000 </li>
<li>Requests per feature per month 20,000,000 </li>
<li>Images per second 8 </li>
<li>Images per request 16 </li>
</ul>
