+# routecheck
+
+FastAPI service providing a Yandex Routing API proxy behind an image captcha.
+
+## Purpose
+
+Yandex Routing API free tier requires a website that uses the API. This service is that website.
+It also exposes an internal endpoint (`/api/route`) used by `CommuteTool` in `fast_tools.py`.
+
+## Two access paths
+
+- **Web UI** (`/`): solve PIL arithmetic captcha → get a token → query any two lat/lon points
+- **Internal API**: `GET /api/route?from=lat,lon&to=lat,lon&token=$ROUTECHECK_TOKEN` — no captcha
+
+## Key env vars
+
+- `YANDEX_ROUTING_KEY` — from developer.tech.yandex.ru, Router API, free tier
+- `INTERNAL_TOKEN` — equals `ROUTECHECK_TOKEN` from root `.env`; shared with deepagents
+- `HTTPS_PROXY` — set to `http://host.docker.internal:56928`; container has no direct external internet
+
+## Notes
+
+- Captchas expire after 5 min, route tokens after 1 hour, both stored in-memory (restart clears them)
+- Yandex API expects `lon,lat` order (not `lat,lon`) — `app.py` swaps automatically
+- Captcha image endpoint: `GET /captcha/image/{id}` — regenerates on each call with random noise
