Overview
ipapi.com provides a fast REST API to geolocate any IP address and retrieve location data like country, city, timezone, and ISP in JSON format. It offers a free plan with 1,000 requests per month so you can prototype without a billing setup. It is a good fit for apps that need to detect a user's location automatically from their IP.
Beginner Tip
You can test the API without a key by hitting the /json endpoint — it will geolocate your own request IP. Add your API key as ?access_key=YOUR_KEY for higher limits and full field access.
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.ipapi.com/api/134.201.250.155?access_key=YOUR_API_KEY";
// 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?
