Overview

IPInfoDB offers free geolocation lookups that map IP addresses to country, region, city, and time zone data. Registration is required but free, and the service provides simple RESTful endpoints with JSON or XML output. It is a reliable choice for projects that need basic IP-to-location functionality without a high budget.

Beginner Tip

Register for a free API key at ipinfodb.com. Use the city-level endpoint for the most detailed location data, and add format=json to your request to get machine-readable JSON back.

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.

IP address details
latitude and longitude
city and country
timezone
ISP information
country name and code

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.

JSON Response · Illustrative
{
  "ip": "203.0.113.42",
  "city": "San Francisco",
  "region": "California",
  "country_code": "US",
  "latitude": 37.7749,
  "longitude": -122.4194,
  "timezone": "America/Los_Angeles",
  "isp": "Example ISP"
}

Field Reference

statusCode OK when the request succeeds, otherwise an error code.
countryCode Two-letter ISO country code for the IP.
regionName State or region name within the country.
cityName City name associated with the IP address.
timeZone UTC offset string for the location, e.g. -05:00.
ipAddress The IP address that was looked up in the request.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request
const url = "https://api.ipinfodb.com/v3/ip-city/?key=YOUR_API_KEY&ip=8.8.8.8&format=json";
// 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);

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.

ERROR - Invalid API key The key parameter is absent or contains an error.
Copy the API key exactly from your IPInfoDB account page and pass it as key=YOUR_API_KEY.
ERROR - Invalid IP address A private, malformed, or IPv6 address was sent.
Use a valid public IPv4 address such as 8.8.8.8 for testing.
ERROR - Your account is not activated You registered but have not confirmed your email.
Check your inbox for the activation email from IPInfoDB and click the confirmation link.

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.
