Are you tired of wrestling with raw cURL requests, parsing Server-Sent Events (SSE) by hand, and building complex polling loops just to interact with trading APIs? If you are a PHP developer or a Laravel enthusiast looking to dive into algorithmic trading, your life is about to get a whole lot easier. Meet coinquant-php, the official PHP and Laravel SDK for the CoinQuant Public API.

CoinQuant is revolutionizing the way we approach algorithmic trading. It takes a trading idea described in plain English and turns it into a backtestable strategy using advanced AI. However, integrating such powerful tools into your own applications can often be a daunting task. That is where coinquant-php steps in. This robust SDK wraps the public API, providing a seamless, developer-friendly experience that lets you focus on what really matters: building profitable trading strategies.

In this comprehensive guide, we will explore why coinquant-php is a game-changer for PHP developers, delve into its standout features, and show you how to get started in minutes.

Why Choose CoinQuant PHP?

The landscape of algorithmic trading is often dominated by Python, but PHP remains a powerhouse for web development, especially with frameworks like Laravel. coinquant-php bridges the gap, allowing PHP developers to leverage the cutting-edge AI capabilities of CoinQuant without leaving their preferred ecosystem.

1. Built for Modern PHP

The library is designed for the modern era of PHP. It requires PHP 8.1+ and embraces strict typing, ensuring your code is robust and free from legacy baggage. Whether you are building a standalone script or a complex enterprise application, the SDK provides a solid foundation.

2. First-Class Laravel Integration

If you are using Laravel 10, 11, 12, or 13, you are in for a treat. The package auto-registers its ServiceProvider and Facade, meaning there is absolutely zero manual wiring required. You can simply install the package and start using the CoinQuant facade anywhere in your controllers, jobs, or commands. It also binds the client as a singleton for elegant dependency injection.

3. Comprehensive API Coverage

The SDK doesn't just cover the basics; it provides access to all 37 public endpoints of the CoinQuant API. This includes health checks, chat interactions, strategy generation, versioning, backtesting, reports, templates, credit management, and even community features like leaderboards. Everything you need is right at your fingertips.

4. Effortless Streaming via Generators

One of the most powerful features of CoinQuant is its AI engine, which responds over Server-Sent Events (SSE). Handling SSE in PHP can be tricky, but the SDK abstracts this away completely. It reads the stream and classifies events into categories like chat, strategy, report, error, or unknown. You can even iterate over the generator directly to stream tokens to a browser in real-time, creating a highly responsive user experience.

5. Simplified Backtesting

Backtesting is the core of algorithmic trading, and coinquant-php makes it incredibly simple. The createBacktestAndWait() method is a one-call solution that submits the run, polls until completion, and returns the final results along with CSV exports for deep analysis.

6. Actionable Exceptions

Debugging API integrations can be frustrating, but not with this SDK. Any non-2xx response throws a CoinQuantException that carries the HTTP status, a unique request_id, a machine-readable code, and a descriptive message. This makes error handling and troubleshooting a breeze.

Getting Started: From Zero to Backtest

Let's walk through how easy it is to get started with coinquant-php.

Installation

First, pull the package in via Composer. Guzzle, the underlying HTTP client, is installed automatically.

composer require tigusigalpa/coinquant-php

Enter fullscreen mode Exit fullscreen mode

Configuration

CoinQuant uses a JWT bearer token for authentication. You can generate one from the Settings menu in the CoinQuant web app. Keep this token secure in an environment variable (COINQUANT_TOKEN).

For standalone PHP:

use CoinQuant\CoinQuantClient;

$client = new CoinQuantClient(getenv('COINQUANT_TOKEN'));
$credits = $client->getCredits();

echo "Available credits: {$credits['available_credits_total']}";

Enter fullscreen mode Exit fullscreen mode

For Laravel, simply add the token to your .env file:

COINQUANT_TOKEN=your_token_here

Enter fullscreen mode Exit fullscreen mode

And you are ready to use the facade:

use CoinQuant\Laravel\Facades\CoinQuant;

$credits = CoinQuant::getCredits();

Enter fullscreen mode Exit fullscreen mode

The Workflow: Idea to Metrics

The true power of the SDK shines when you use it to turn an idea into a fully backtested strategy. Here is a complete workflow in just a few lines of code:

// 1. Describe the idea and let the AI draft a strategy.
$res = $client->prompt('Long BTCUSDT when price crosses above the 200 EMA on 1h, exit on cross below.');

// 2. Materialize it if it came back schema-only.
$versionId = $res->strategyVersionId
    ?? $client->finalizeChat($res->chatId, 'EMA 200 Crossover', '')['latest_version']['id'];

// 3. Backtest and wait for the verdict.
$outcome = $client->createBacktestAndWait($versionId, 900, 5);

// 4. Analyze the results
print_r($outcome['results']['metrics']);

Enter fullscreen mode Exit fullscreen mode

In this example, we simply ask the AI to create a strategy based on the 200 EMA crossover. The SDK handles the streaming response, materializes the strategy blueprint into a backtestable version, runs the backtest, and polls for the results. It is algorithmic trading made remarkably accessible.

Advanced Usage: Streaming and Customization

For developers who need more control, coinquant-php delivers.

Real-Time Streaming

If you are building a user interface and want to show the AI's thought process in real-time, you can iterate the generator directly:

use CoinQuant\Streaming\StreamEvent;

foreach ($client->streamPrompt('Explain the RSI indicator.') as $event) {
    if ($event->type === StreamEvent::TYPE_CHAT) {
        echo $event->text; // Flush to the client in real time
    }
}

Enter fullscreen mode Exit fullscreen mode

Custom HTTP Clients

Under the hood, the SDK uses Guzzle. If you need to configure retries, route traffic through a proxy, or add custom headers for tracing, you can pass your own configured Guzzle client:

use GuzzleHttp\Client as GuzzleClient;

$http = new GuzzleClient([
    'timeout' => 60,
    'headers' => ['Authorization' => 'Bearer ' . getenv('COINQUANT_TOKEN' )],
]);

$client = new CoinQuantClient(getenv('COINQUANT_TOKEN'), $http );

Enter fullscreen mode Exit fullscreen mode

Conclusion

The coinquant-php SDK is a masterclass in developer experience. By abstracting away the complexities of the CoinQuant API, SSE parsing, and asynchronous polling, it empowers PHP developers to build sophisticated trading applications with unprecedented speed and ease.

Whether you are a solo developer exploring algorithmic trading or a team building a comprehensive financial platform on Laravel, this SDK provides the tools you need to succeed. The strict typing, elegant Laravel integration, and comprehensive endpoint coverage make it a joy to use.
