# Carpathian Maps

> Self-hosted maps and directions. A public vector map that any MapLibre client can draw, and a keyed HTTP API for walk, bike, drive and transit routes and isochrones.

- Map files are public at https://maps.carpathian.ai/map and need no key.
- `POST /v1/route` and `POST /v1/isochrone` need `Authorization: Bearer <key>`. Call them from a backend; never ship the key to a browser or app.
- The server never logs bodies, coordinates or query strings.
- Directions cover Iowa (walk, bike and drive); Des Moines metro IA (transit on DART). A point outside them answers `422 No route was found.`

## Docs

- [Overview](https://maps.carpathian.ai/docs/index.md): Carpathian Maps is self-hosted maps and directions. One server holds the map, the route engines and the key, so no third party sees where anyone is or where they are going.
- [Connect](https://maps.carpathian.ai/docs/connect.md): Two things connect to Carpathian Maps: the map, which any browser or app draws from the public map files, and directions, which your backend asks for with the key.
- [API reference](https://maps.carpathian.ai/docs/api.md): The directions API answers walk, bike, drive and transit routes and isochrones from your backend.
