Overview

Telize is an IP geolocation API that returns detailed location and network information for any IP address, including country, city, coordinates, timezone, and ISP. Available via RapidAPI, it requires an API key to authenticate your requests. It is useful for analytics, fraud detection, and personalization features.

💡

Beginner Tip

Omit the IP address parameter to automatically geolocate the requesting client IP, which is useful for detecting your own location during testing. Always handle cases where geolocation returns null for private or unknown IPs.

Available Data

IP address information
geographic location
ASN and ISP data

  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

403 Forbidden or missing RapidAPI headers The required RapidAPI authentication headers are absent.
✓ Include X-RapidAPI-Key and X-RapidAPI-Host: telize.p.rapidapi.com in every request.
Private IP address returns empty location Local or private IP ranges (10.x.x.x, 192.168.x.x) cannot be geolocated.
✓ Use a real public IP address for testing. You can get your public IP from https://api.ipify.org first.
429 Too Many Requests Free tier rate limit exceeded on RapidAPI.
✓ Monitor your usage in the RapidAPI dashboard and implement request caching to reduce repeated lookups for the same IP.
