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.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Implementation Example
Calls a real endpoint of this API. Replace any placeholder credentials with your own key.
const url = "https://api.geodatasource.com/city?key=YOUR_API_KEY&lat=40.7128&lng=-74.0060";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
headers: {
"X-API-Key": "YOUR_API_KEY"
}
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
