# Kviria

- [Introduction](https://docs.kviria.com/index.md): Kviria turns a user's words into one verified place - a deterministic location engine for AI agents. One endpoint, your wallet is your account, San Francisco (beta).

- [Quickstart](https://docs.kviria.com/quickstart.md): Get your first verified coordinate in under a minute.

- [Echo state](https://docs.kviria.com/how-it-works/echo-state.md): Your agent holds the conversation state; Kviria stays stateless.
- [Determinism](https://docs.kviria.com/how-it-works/determinism.md): Same input, same answer - and the trail that proves it.
