Overview

Icanhazip returns your public IP address as a plain text string with no authentication, parsing, or configuration needed. It is one of the oldest and most widely used IP detection services, commonly embedded in shell scripts and network configuration tools. Both IPv4 (icanhazip.com) and IPv6 (ipv6.icanhazip.com) variants are available.

Beginner Tip

Just curl the URL and you get your IP address back as plain text — it is that simple. This is an ideal first API call for anyone new to curl or HTTP. Use it in shell scripts with MY_IP=$(curl -s https://icanhazip.com) to capture your current public IP into a variable.

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.

ASN and ISP data
Use case: Integrate ip address api data into web and mobile applications

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.

Field Reference

(plain text body) Your public IP address as a plain text string, either IPv4 or IPv6 depending on your network stack.

Implementation Example

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

Request
const url = "https://icanhazip.com";
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.

Returns IPv6 address unexpectedly Your machine prefers IPv6 and the resolver returns AAAA records
Use curl -4 https://icanhazip.com to force IPv4, or use https://ipv4.icanhazip.com explicitly.
Trailing newline in response The API appends a newline character after the IP
Trim the response: in bash use $(curl -s https://icanhazip.com | tr -d newline).
429 rate limit Too many requests from the same IP in a short time
Add delays between requests; for high-frequency use consider ipify.org which has a more generous rate limit.

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.
