Code examples

Copy an own-IP request in JavaScript, cURL, Python or Go.

Own-IP request examples

Each example calls the same endpoint. The connecting process determines whose IP address is returned.

Use a JavaScript module or browser console with native fetch and AbortSignal.timeout.

Own-IP request

const response = await fetch(
  "https://api.ipquery.io/?format=json",
  { signal: AbortSignal.timeout(5000) }
);
if (!response.ok) {
  const message = await response.text();
  throw new Error("IPQuery " + response.status + ": " + message);
}
const data = await response.json();
console.log(JSON.stringify(data, null, 2));

Python 3, standard library only. The timeout applies to socket operations.

Own-IP request

import json
from urllib.request import urlopen

with urlopen("https://api.ipquery.io/?format=json", timeout=5) as response:
    data = json.load(response)

print(json.dumps(data, indent=2))

Go, standard library only. Save as main.go and run go run main.go.

Own-IP request

package main

import (
    "io"
    "log"
    "net/http"
    "os"
    "time"
)

func main() {
    client := &http.Client{Timeout: 5 * time.Second}
    response, err := client.Get("https://api.ipquery.io/?format=json")
    if err != nil { log.Fatal(err) }
    defer response.Body.Close()
    if response.StatusCode != http.StatusOK {
        log.Fatalf("IPQuery %s", response.Status)
    }
    if _, err := io.Copy(os.Stdout, response.Body); err != nil {
        log.Fatal(err)
    }
}

The examples use five-second timeouts and the language’s standard HTTP tools. Handle failures in your application; do not substitute an empty IP record.
