Overview

IP 2 Country is a free, no-auth API that maps any IPv4 address to its corresponding country. It is useful for basic geolocation features like redirecting users or showing region-specific content. Just pass an IP address as a query parameter to get the country code back.

Beginner Tip

This API only returns country-level data, not city or region. For more detailed IP geolocation, consider ipinfo.io or ip-api.com. It works well as a lightweight first step for country detection in backend scripts.

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.

Request
const url = "https://api.ip2country.info/ip?8.8.8.8";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

Empty or null country response The IP address is a private, reserved, or loopback address like 127.0.0.1.
Only pass public IPv4 addresses. Test with a real external IP like 8.8.8.8 first.
400 Bad Request The IP address format is invalid.
Ensure the IP is a valid IPv4 format (e.g. 203.0.113.45) without extra characters or spaces.
Unknown country code Some IPs are not mapped in the database.
Handle missing or null results gracefully in your code with a fallback value.

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.
