Our CraftAR Image Recognition API allows you to integrate our cloud image recognition service into your branded mobile and web applications. More specifically, the API conforms to the RESTful constrains and permits you to perform visual recognition against one of your collections of reference images by sending HTTP requests. The results are returned in JSON format.
We provide PHP and Python libraries for the Image Recognition API. Thanks to our customers, we also have implementations of this API for .NET.
