Postman Setup Guide

Get Postman ↗
  1. No API key needed for demo server
  2. GET /route/v1/{profile}/{lon1,lat1};{lon2,lat2}
  3. Profiles: driving, cycling, foot
  4. Try: /route/v1/cycling/-0.127,51.507;-0.075,51.508?steps=true&geometries=geojson
  5. Self-host for production to avoid demo server limits

What can you build with OSRM Routing API?

OSRM Routing API is a Location API. Developers commonly use location APIs for:

  • tracking assets and vehicles in real time
  • building delivery and logistics apps
  • finding nearby businesses or services
  • geo-fencing and location-based notifications
  • address validation and autocomplete

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. OSRM Routing API is free to use, making it a low-risk choice to experiment with.
