Laravel wrapper for Anthropic PHP, the community-maintained PHP SDK for the Anthropic API. Adds a Facade, a publishable config, an install command, and a testing integration that plugs into the service container.

I maintain this package along with several other open-source PHP packages used by thousands of developers every day.

Anthropic:: Facade for everything. Anthropic::messages(), Anthropic::models(), Anthropic::batches(), Anthropic::files(), Anthropic::completions(). No client instantiation, no factory setup. The service provider handles it.

Anthropic::fake() in your tests. Swap the real client with a fake, queue responses, and assert exactly which requests were sent. Pairs with Laravel's existing testing idioms like Event::fake() and Queue::fake(). See the testing docs →

use Anthropic\Laravel\Facades\Anthropic;
use Anthropic\Resources\Messages;
use Anthropic\Responses\Messages\CreateResponse;

Anthropic::fake([
    CreateResponse::fake([
        'content' => [['type' => 'text', 'text' => 'Paris is the capital of France.']],
    ]),
]);

// Run your code...

Anthropic::assertSent(Messages::class, function (string $method, array $parameters) {
    return $parameters['model'] === 'claude-sonnet-4-6';
});

One artisan command to set up. php artisan anthropic:install publishes the config file and appends ANTHROPIC_API_KEY= to your .env. You're ready to go.

Forward-compatible. Parameters pass through to the API as-is. When Anthropic ships a new feature, it works in your code the same day. No waiting for a package update.

Full Anthropic API coverage. Messages, streaming, tool use, extended thinking, web search, code execution, citations, token counting, and batch processing. Every feature the API supports is available through the Facade.

Requires PHP 8.2+ - see all version requirements

composer require mozex/anthropic-laravel

Run the install command:

php artisan anthropic:install

This publishes config/anthropic.php and appends ANTHROPIC_API_KEY= to your .env. Set your key from the Anthropic Console:

ANTHROPIC_API_KEY=sk-ant-...

Use the Anthropic Facade anywhere in your app:

use Anthropic\Laravel\Facades\Anthropic;

$response = Anthropic::messages()->create([
    'model' => 'claude-sonnet-4-6',
    'max_tokens' => 1024,
    'messages' => [
        ['role' => 'user', 'content' => 'Hello!'],
    ],
]);

echo $response->content[0]->text; // Hello! How can I assist you today?

Print text as it arrives:

$stream = Anthropic::messages()->createStreamed([
    'model' => 'claude-sonnet-4-6',
    'max_tokens' => 1024,
    'messages' => [
        ['role' => 'user', 'content' => 'Tell me a short story.'],
    ],
]);

foreach ($stream as $response) {
    if ($response->type === 'content_block_delta'
        && $response->delta->type === 'text_delta') {
        echo $response->delta->text;
    }
}

Give Claude tools to call, execute them in your code, send results back:

$response = Anthropic::messages()->create([
    'model' => 'claude-sonnet-4-6',
    'max_tokens' => 1024,
    'tools' => [
        [
            'name' => 'get_weather',
            'description' => 'Get the current weather in a given location',
            'input_schema' => [
                'type' => 'object',
                'properties' => [
                    'location' => ['type' => 'string'],
                ],
                'required' => ['location'],
            ],
        ],
    ],
    'messages' => [
        ['role' => 'user', 'content' => 'What is the weather in San Francisco?'],
    ],
]);

$response->content[1]->name;              // 'get_weather'
$response->content[1]->input['location']; // 'San Francisco'

Let Claude reason through complex problems before answering:

$response = Anthropic::messages()->create([
    'model' => 'claude-opus-4-6',
    'max_tokens' => 16000,
    'thinking' => ['type' => 'adaptive'],
    'messages' => [
        ['role' => 'user', 'content' => 'What is the GCD of 1071 and 462?'],
    ],
]);

$response->content[0]->thinking; // 'Using the Euclidean algorithm...'
$response->content[1]->text;     // 'The GCD of 1071 and 462 is 21.'
