In order to be able to use the image analysis for images we need to be provided with a Google Natural Language API key which has an extra cost for the customer for the user that will be billed separately by Google and it is 100% independent of the Graphext billing(for any doubts send an email to the Graphext team). More information about the cost can be found in the bottom of the Google Vision API page.

1.- Avoid this step if you already have a Google Cloud Platform account Enter the Google Vision API webpage and click Probar Gratis or Try It Free and create your Google Cloud Platform account.
