Overview
CountryStateCity provides a comprehensive API with world countries, states, regions, and cities data in multiple formats including JSON, SQL, and CSV. It is perfect for building address forms, dropdown menus, or any feature that needs structured geographic data. An API key is required but free registration is available.
Beginner Tip
Start by fetching the list of all countries to get country ISO codes, then use those codes to fetch states and cities. Cache the responses since this data rarely changes.
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.countrystatecity.in/v1/countries";
// 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?
