# Kviria > Location understanding for AI agents: know where, then navigate there. > Beta: contiguous US. The agent parses what the user said into a > request; Kviria narrows it down to exactly one place or address and > returns its verified coordinate with an evidence trail. Data only - > never phrased sentences; the agent phrases. ## Agent Docs - [Skill](https://kviria.com/skill.md): The agent-facing contract - when to call, what to send, the decisions and what to do with each, errors, examples. - [Tool definition](https://kviria.com/tool-definition.json): The authoritative wire schema (JSON Schema, MCP-ready). ## API - Endpoint: POST https://api.kviria.com/v1/agent - Auth: a Kviria key (Authorization: Bearer kvr_..., from https://api.kviria.com/key), or OAuth for MCP clients; no email or password.
