FAQ

Is this IP API really free?
Yes. The /ip endpoint is completely free with no API key required. It is rate-limited to 120 requests per minute to prevent abuse, which is more than enough for any typical application.
Do I need an API key?
No. The /ip, /ip/json, and /ip/geo/:address endpoints are completely public. No signup, no API key, no authentication. Just send a request and get a response.
Can I use this as a drop-in replacement for ipify?
Yes. GET /ip returns your IP as plain text, just like ipify.org. GET /ip?format=json returns JSON. Additionally, /ip/json includes geolocation data that ipify doesn't provide.
Does this API support CORS?
Yes. The API returns Access-Control-Allow-Origin: * headers, so you can use it directly from browser JavaScript with fetch() or XMLHttpRequest.
What geolocation data is included?
The /ip/json endpoint returns: IP address, country code, region, city, timezone, latitude, longitude, and EU membership status.
How does this compare to ip-api.com?
Unlike ip-api.com, this API uses HTTPS on the free tier (ip-api requires a paid plan for HTTPS). Our rate limit is also higher at 120 req/min vs their 45 req/min.
Can I look up any IP, not just my own?
Yes. Use GET /ip/geo/8.8.8.8 (replace with any IP) to look up geolocation for any IPv4 or IPv6 address. For batch lookups of up to 100 IPs, get a free API key and use the full geolocation API.
