Send messages, stream responses, call tools, use extended thinking, search the web, execute code, process batches, and more. Works with any PSR-18 HTTP client. > **[Read the full documentation at mozex.dev](https://mozex.dev/docs/anthropic-php/v1)**: searchable docs, version requirements, detailed changelog, and more. > **Using Laravel?** Check out [Anthropic Laravel](https://github.com/mozex/anthropic-laravel), which wraps this SDK with service container integration, config-based setup, and a facade.

If my packages save you time or help your business, consider [**sponsoring my work on GitHub Sponsors**](https://github.com/sponsors/mozex). Your support lets me keep these packages updated, respond to issues quickly, and ship new features. Business sponsors get logo placement in package READMEs. [**See sponsorship tiers →**](https://github.com/sponsors/mozex) Why This Package ---------------- [](#why-this-package) **Built-in test client.** Swap `Anthropic\Client` with `ClientFake` in your tests, queue fake responses, and assert exactly which requests were sent. No HTTP mocking libraries needed, no test server to run. [See the testing docs →](https://mozex.dev/docs/anthropic-php/v1/reference/testing) ``` use Anthropic\Testing\ClientFake; use Anthropic\Responses\Messages\CreateResponse; $client = new ClientFake([ CreateResponse::fake([ 'content' => [['type' => 'text', 'text' => 'Paris is the capital of France.']], ]), ]); $response = $client->messages()->create([...]); $client->assertSent(Messages::class, function (string $method, array $parameters): bool { return $parameters['model'] === 'claude-sonnet-4-6'; }); ``` **Forward-compatible.** Parameters pass through to the API as-is. When Anthropic ships a new feature (a new tool type, a new thinking mode, a new parameter), it works in your code the same day. You don't wait for an SDK release. **Typed, immutable responses.** Every response is a `readonly` PHP object with typed properties. Access `$response->usage->inputTokens`, not `$response['usage']['input_tokens']`. Full IDE autocompletion, no guessing. **Rate limits on every response.** Call `$response->meta()` on any response (including streams and batch results) to get your current request limits, token limits, and reset times. **Any HTTP client.** Built on PSR-18, so it works with Guzzle, Symfony HTTP Client, Buzz, or whatever your project already uses. No vendor lock-in. Installation ------------ [](#installation) > **Requires [PHP 8.2+](https://www.php.net/releases/)** - see [all version requirements](https://mozex.dev/docs/anthropic-php/v1/requirements) ``` composer require mozex/anthropic-php ``` The included `php-http/discovery` plugin finds and installs a compatible PSR-18 HTTP client automatically. If you want to use a specific one (like Guzzle or Symfony), see [Configuration](https://mozex.dev/docs/anthropic-php/v1/reference/configuration). Quick Start ----------- [](#quick-start) Create a client, send a message, read the response: ``` $client = Anthropic::client('your-api-key'); $response = $client->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? ``` ### Streaming [](#streaming) Print text as it arrives: ``` $stream = $client->messages()->createStreamed([ 'model' => 'claude-sonnet-4-6', 'max_tokens' => 1024, 'messages' => [ ['role' => 'user', 'content' => 'Tell me a short story.'], ], ]); foreach ($stream as $response) { if ($response->type === 'content_block_delta' && $response->delta->type === 'text_delta') { echo $response->delta->text; } } ``` ### Tool Use [](#tool-use) Give Claude tools to call, execute them in your code, send results back: ``` $response = $client->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' ``` ### Extended Thinking [](#extended-thinking) Let Claude reason through complex problems before answering: ``` $response = $client->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?'], ], ]); // Thinking block with Claude's reasoning process $response->content[0]->thinking; // 'Using the Euclidean algorithm...' // Final answer $response->content[1]->text; // 'The GCD of 1071 and 462 is 21.' ``` ### Configuration [](#configuration) For custom base URIs, timeouts, or HTTP clients, use the factory: ``` $client = Anthropic::factory() ->withApiKey('your-api-key') ->withBaseUri('anthropic.example.com/v1') ->withHttpClient(new \GuzzleHttp\Client(['timeout' => 120])) ->withHttpHeader('X-Custom-Header', 'value') ->make(); ``` The [full documentation](https://mozex.dev/docs/anthropic-php/v1) covers every feature in detail: [web search and code execution](https://mozex.dev/docs/anthropic-php/v1/usage/server-tools), [document citations](https://mozex.dev/docs/anthropic-php/v1/usage/citations), [token counting](https://mozex.dev/docs/anthropic-php/v1/usage/token-counting), [batch processing](https://mozex.dev/docs/anthropic-php/v1/usage/batches), [error handling](https://mozex.dev/docs/anthropic-php/v1/reference/error-handling), [rate limits](https://mozex.dev/docs/anthropic-php/v1/reference/meta-information), and [more](https://mozex.dev/docs/anthropic-php/v1).
