If you’re looking for a geospatial data API for reverse geocoding, you’re usually trying to convert:
latitude + longitude → address / place / administrative area
Common reverse geocoding API options
-
Google Maps Geocoding API
- Very accurate, widely used
- Paid beyond free tier
- Good global coverage
-
Mapbox Geocoding API
- Strong developer experience
- Good for maps + location services
- Paid with limited free tier
-
OpenStreetMap-based services
- Nominatim (free, but usage limits apply)
- Good for prototyping and smaller workloads
- Requires caution for heavy production use
-
HERE Reverse Geocoding API
- Good enterprise/location platform option
-
Geoapify
- Easy to use, OSM-based, generous free tier for some use cases
-
TomTom Search API
- Another commercial option with reverse geocoding support
Typical request
Example reverse geocoding call usually looks like:
GET /reverse?lat=40.7128&lon=-74.0060
Typical response
{
"address": "New York, NY, USA",
"city": "New York",
"state": "New York",
"country": "United States"
}
Important considerations
- Accuracy: rooftop vs street vs city-level
- Rate limits: free tiers can be strict
- Licensing: especially with OpenStreetMap/Nominatim
- Caching: recommended if you’ll repeat queries
- Latency: can matter for mobile or real-time apps
If you want to build your own
You’d typically use:
- a geospatial database like PostGIS
- a geocoder like Nominatim
- or a commercial geocoding service
If you want, I can also give you:
- a Python example
- a JavaScript example
- a FastAPI/Flask endpoint
- or a comparison table of the best reverse geocoding APIs
