```javascript
// An example script doing a batch request

// List of IP addresses to query, up to 100
var IPs = ["208.80.152.201", "8.8.8.8", "24.48.0.1"];

// ip-api endpoint URL
// see http://ip-api.com/docs/api:batch for documentation
var endpoint = 'http://ip-api.com/batch';

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
	if (this.readyState == 4 && this.status == 200) {
		// Result array
		var response = JSON.parse(this.responseText);
		console.log(response);
		response.forEach(function (item) {
			console.log(item.query + " is in " + item.city + ", " + item.country);
		});
	}
};
var data = JSON.stringify(IPs);
console.log("sending:", data);

xhr.open('POST', endpoint, true);
xhr.send(data);
```

```javascript
// An example script for finding out the distance from the user to multiple points

// Coordinates and name
var coords = [

	{lat: 47.6062095, lon: -122.3320708, name: 'Seattle, WA'},
	];

// ip-api endpoint URL
// see http://ip-api.com/docs/api:json for documentation
var endpoint = 'http://ip-api.com/json/?fields=status,message,lat,lon';

function getDistanceFromLatLonInKm(lat1, lon1, lat2, lon2) {
	var R = 6371; // Radius of the earth in km
	var dLat = deg2rad(lat2-lat1);  // deg2rad below
	var dLon = deg2rad(lon2-lon1); 
	var a =

		Math.sin(dLon/2) * Math.sin(dLon/2);
	var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)); 
	var d = R * c; // Distance in km
	return d;
}

function deg2rad(deg) {
	return deg * (Math.PI/180)
}

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
	if(this.readyState == 4 && this.status == 200) {
		var response = JSON.parse(this.responseText);
		if(response.status !== 'success') {
			console.log('query failed: ' + response.message);
			return
		}
		// Distance in kilometers for each coordinate
		for(var i = 0; i < coords.length; i++) {
			var diff = getDistanceFromLatLonInKm(coords[i].lat, coords[i].lon, response.lat, response.lon);

### Usage Limits and Best Practices

Source: https://ip-api.com/docs/api%3Ajson

Details on request limits, throttling, IP bans, and recommended handling of rate limit headers.

```APIDOC
## Usage Limits

This endpoint is limited to **45** requests per minute from an IP address. If you exceed the limit, requests will be throttled (`HTTP 429`) until the rate limit window resets. Continuous exceeding of the limit may result in an IP ban for 1 hour.

### Rate Limit Headers

- `X-Rl`: The number of requests remaining in the current rate limit window.
- `X-Ttl`: The number of seconds until the rate limit window resets.

**Recommendation:** Always check the `X-Rl` header. If it is 0, do not send further requests for the duration specified by `X-Ttl`.

### Commercial Use

Commercial use of this endpoint is not permitted. For commercial needs, please refer to the pro service for SSL access, unlimited queries, and commercial support.

## API Usage and Limits

### Testing the API

**Test via Google Public DNS:**
```bash
API_HOST=$(</dev/urandom tr -dc a-z0-9|head -c32).edns.ip-api.com; API_IP=$(dig $API_HOST +short @8.8.8.8); curl -H "Host: $API_HOST" http://$API_IP/json
```

**Test via OpenDNS:**
```bash
API_HOST=$(</dev/urandom tr -dc a-z0-9|head -c32).edns.ip-api.com; API_IP=$(dig $API_HOST +short @208.67.222.222); curl -H "Host: $API_HOST" http://$API_IP/json
```

### Callback (JSONP)
By default, no callback function is invoked. You can specify a custom callback function using the `callback` GET parameter.

**Example:** `http://edns.ip-api.com/json/?callback=myCallback`

### JavaScript: Redirect users based on country code

Source: https://ip-api.com/docs/api%3Ajson

This JavaScript snippet demonstrates how to redirect users to different websites based on their country code. It uses the ip-api.com JSON endpoint to fetch the country code and then performs the redirection using `window.location.replace()`. Ensure the `endpoint` variable correctly points to the ip-api.com JSON endpoint with the required `fields` parameter.

```javascript
// An example script for redirecting users from USA to https://google.com/
// and users from Canada to https://google.ca/

// ip-api endpoint URL
// we need only the countryCode, but you can request more fields
// see http://ip-api.com/docs/api:json for documentation
var endpoint = 'http://ip-api.com/json/?fields=status,message,countryCode';

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
	if (this.readyState == 4 && this.status == 200) {
		var response = JSON.parse(this.responseText);
		if(response.status !== 'success') {
			console.log('query failed: ' + response.message);
			return
		}
		// Redirect
		if(response.countryCode == "US") {
			window.location.replace("https://google.com/");
		}
		if(response.countryCode == "CA") {
			window.location.replace("https://google.ca/");
		}
	}
};
xhr.open('GET', endpoint, true);
xhr.send();

### Fetch IP Geolocation Data using Batch Request (PHP)

Source: https://ip-api.com/docs/api%3Abatch

This PHP script demonstrates how to perform a batch request to the ip-api.com API to retrieve geolocation data for multiple IP addresses. It sends a POST request with a JSON-encoded array of IP addresses to the batch endpoint and then decodes and prints the JSON response.

```php
<?php
// An example script doing a batch request

// List of IP addresses to query, up to 100
$ips = ['208.80.152.201', '8.8.8.8', '24.48.0.1'];

// ip-api endpoint URL
// see http://ip-api.com/docs/api:batch for documentation
$endpoint = 'http://ip-api.com/batch';

$options = [
	'http' => [
		'method' => 'POST',
		'user_agent' => 'Batch-Example/1.0',
		'header' => 'Content-Type: application/json',
		'content' => json_encode($ips)
	]
];
$response = file_get_contents($endpoint, false, stream_context_create($options));

// Decode the response and print it
$array = json_decode($response, true);
print_r($array);
?>
