Overview

GeoDataSource lets you look up city names from latitude and longitude coordinates, making it simple to reverse-geocode a GPS position into a readable location. It also supports distance calculations between coordinates and city-to-coordinate lookups. A free tier is available with a limited number of daily API calls.

Beginner Tip

Use the free-tier endpoint to reverse-geocode coordinates into city names — it is the simplest starting point and requires only a latitude, longitude, and your API key.

Common Errors & Troubleshooting

{"status":"INVALID_API_KEY"} The API key provided is missing or incorrect.
✓ Sign up at geodatasource.com and replace YOUR_API_KEY with your actual key.
{"status":"OVER_QUERY_LIMIT"} You have exceeded the daily request limit on the free plan.
✓ Wait until the next day for the limit to reset, or upgrade to a paid plan for higher quotas.
Empty city field in response The coordinates provided are in an ocean, uninhabited area, or are malformed.
✓ Verify the lat/lng values are valid decimal degrees (e.g. lat between -90 and 90, lng between -180 and 180).

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
