Crate tail_fin_gemini 

Gemini adapter — talks to gemini.google.com’s internal web API using cookies from a signed-in session. No Chrome, no DOM scraping.

Uses your Google One AI Premium / Advanced subscription (whatever your logged-in browser account has).

Typical use

use std::path::Path;
use tail_fin_gemini::GeminiClient;

let client = GeminiClient::from_cookie_file(Path::new("~/.tail-fin/gemini-cookies.txt"))?;
let reply = client.ask("Hello Gemini", None).await?;
println!("{}", reply.response);
