limit-by-ip-rotation

Problem:

Struggling with 3rd party API limit, they limit n requests per second per IP address

Expected:

Easily call api without

Solution:

By using this package, you're using:

• ip rotation via proxy
• rate limiter to control request rate

Installation

You can install this lib by 2 methods:

using composer

This project using composer.

composer require mars-php-utils/rate-limit-bypass

Manual install

checkout repos at:

vendor_dev/rate-limiter-bypass

composer.json

"repositories": [
    {
        "type": "path",
        "url": "vendor_dev/rate-limiter-bypass"
    }
],

How to use

Assuming you're using curl to make request:

function getUser($id) {
    $curl = curl("https://example-api.com/user/$id");
    curl_setopt_array($curl, $your_options);
    $response = curl_exec($curl);
    return $response;
}

You just need to:

use RateLimitBypass\IpRateLimitHelper;


$max_request_per_second = 10;
$proxies = [...];
$rotator = new IpRateLimitHelper($proxies, $max_request_per_second);

function getUser($id) {
    $proxy_opt = $rotator->tap();
    
    $curl = curl("https://example-api.com/user/$id");

    $your_options = array_merge_recursive($your_options, $proxy_opt);
    
    curl_setopt_array($curl, $your_options);
    $response = curl_exec($curl);
    return $response;
}

Limit by api keys rotation

use RateLimitBypass\ApiKeyRateLimitHelper;

$max_request_per_second = 10;
$api_keys = [...];
$rotator = new ApiKeyRateLimitHelper($api_keys, $max_request_per_second);

function getUser($id) {
    $api_key = $rotator->tap(); // api key can be in query string, headers, path, ... depend on the API endpoint
    
    $curl = curl("https://example-api.com/user/$id?apiKey=$api_key");
    curl_setopt_array($curl, $your_options);
    $response = curl_exec($curl);
    return $response;
}

Local Development

composer.json

"repositories": [
        {

            "url": "vendor_dev/mars-php-utils/rate-limit-bypass"
        }
    ],

then run :

composer require mars-php-utils/rate-limit-bypass

composer will do symlink vendor/mars-php-utils to vendor_dev/mars-php-utils
