Google explicitly allows this and documents how: https://antigravity.google/docs/cli/headless/

Wouldn’t that violate the quoted ToS? I guess it would.

It’s detectable and has been known to result in account bans. People have been doing it since the early days of Gemini, when the ToS was still unclear, and some only found out after their accounts were banned. There have been multiple GitHub issues and reports to Google about it. It’s not worth the effort unless you’re willing to risk a secondary Google account.

I think that is what paseo is doing and I don't risk trying it.
