Why I keep it

I chose Gemini for the voice agent on WithSeismic’s homepage after listening to the options. It asks visitors what they’re trying to do and suggests a next step, but I wanted the call length, prompt and usage limits controlled by the server. The browser gets a single-use token with those choices locked in.

I’ve included the server routes, call guard and browser audio transport, so you can build a conversation around your own business. GUIDE.md explains the timers, Turnstile checks and prompt structure. You write the console UI and fill in the business details; the transport uses a raw WebSocket to keep the browser code lighter.
