You need to have billing enabled for your Google Cloud Platform project.
Evaluated prices can vary and Google gives us this online calculator, or let us test with a FREE account with 300$.
To change the billing account go to the Google Cloud Platform Console.
Open the console left side menu and select Billing.
If you have more than one billing account then you need to solve this issue, see this webpage.
The Cloud Vision API integrates vision features, like: including image labeling, face, logo, and landmark detection, optical character recognition (OCR), and detection of explicit content, into applications.
You need to set the authentification for your google account and your project, see this page.
The next step is to instantiate a client:

client = vision.ImageAnnotatorClient()

Google provides this tutorial with the same steps as into this tutorial.
You can test and read more about Google Vision on the official page.
