I registered google cloud account and want to use Text-To-Speech API on my own server with github.com/googleapis/google-cloud-php library.

On API page in block "Pricing" written that using less than 1 millon chracters/month is free. But lower is a note "Additional charges may also apply from infrastructure you use to call the API"

Question: This note applies to users google cloud VPS, right? If I will use API how I described (send requests from my own server) first million of characters will be absolutely free? Google wont take a cent?

Yes, they mean the Compute Engine. So you pay Google only for API, not for server.
