How to get an API key for Google Cloud Translation

Go to the website https://console.cloud.google.com. Notice the top line. After obtaining the key, you can use it for free for the first 90 days. Specifically, $300 USD will be credited to your Google Cloud account. This amount is sufficient for translating 15 million characters. To continue using Google's cloud service, you need to activate a credit card on the Google Cloud website. Even in this case, you can use the service for free, not exceeding 500,000 characters per month (this corresponds to approximately 180-200 pages of the book). If you exceed these limits, the cost will be proportional to $20 USD per 1 million characters.
