You can geocode addresses to coordinates for free using the OpenStreetMap Nominatim API. This approach converts street addresses into precise latitude and longitude without incurring API costs or compromising user data.

Reverse geocoding finds the address corresponding to a given set of coordinates. Using OpenStreetMap Nominatim, you can perform coordinate-to-address lookups to identify the physical location of specific latitude and longitude points.

Calculate the distance between two geographical points using the Haversine formula. This method computes the distance between latitude and longitude coordinates, which is useful for travel assistants determining proximity to destinations.

Yes, you can handle multiple geocoding requests efficiently using batch processing with rate limiting. This ensures you can process bulk address-to-coordinate conversions while respecting OpenStreetMap API usage policies.

Nearby place searching is supported to discover points of interest like restaurants and cafes near a specific location. You can find local amenities by searching around coordinates obtained through address geocoding.

Nominatim requires rate limiting for batch processing and advanced validation for production-ready applications. You must manage request frequencies carefully to avoid hitting usage limits when converting addresses to coordinates.
