A simple PHP library to connect to Anthropic APIs (Claude).

I created this package to fulfill my own needs on my AI projects. I am aware that there are other similar packages, but either they didn't have all the required features or I just didn't like the implementation and usage.

### Features

[](#features)

- Messages API
- Support multi-content messages (Vision)
- Tool usage (*beta*)
- Completion API (*legacy*)
- Prompt caching (system message only, for now)
- Helps you build and validate messages/tools data structures before sending to the API

#### Roadmap

[](#roadmap)

- Streaming

### Installation

[](#installation)

`composer require nunodonato/anthropic-php`

### Usage

[](#usage)

More soon.

#### Instantiate the client

[](#instantiate-the-client)

```
use NunoDonato\AnthropicAPIPHP\Client;

// ...

$client = new Client($yourApiKey);
```

#### Messages API usage

[](#messages-api-usage)

```
use NunoDonato\AnthropicAPIPHP\Client;
use NunoDonato\AnthropicAPIPHP\Messages;

// ...

$client = new Client($yourApiKey);
$messages = new Messages();
$messages->addUserTextMessage('Hello AI!');

$response = $this->client->messages(Client::MODEL_SONNET, $messages);

// you can chain messages
$messages->addUserTextMessage('Hello AI!')
        ->addAssistantTextMessage('Hello human!')
        ->addUserImageMessage('https://example.com/image.jpg', 'What do you see here?');
```

#### Available models
