Provider setup

All tools read their API credentials from Laravel's services config and their optional defaults from the ai config.

1. Add the Exa service to config/services.php

// config/services.php

return [

    // ... existing services ...

    'exa' => [
        'key' => env('EXA_API_KEY'),
    ],

];

2. Add toolkit defaults to config/ai.php

// config/ai.php

return [

    // ... existing laravel/ai config ...

    'toolkit' => [
        'exa' => [
            'search' => [
                'num_results' => (int) env('EXA_SEARCH_NUM_RESULTS', 10),
                'type' => env('EXA_SEARCH_TYPE', 'auto'),
                'include_text' => (bool) env('EXA_SEARCH_INCLUDE_TEXT', true),
            ],
            'find_similar' => [
                'num_results' => (int) env('EXA_FIND_SIMILAR_NUM_RESULTS', 10),
                'include_text' => (bool) env('EXA_FIND_SIMILAR_INCLUDE_TEXT', true),

Safety

• All tools validate required inputs before calling the API.
• Numeric parameters are clamped to their valid ranges; enums fall back to safe defaults.
• ExaGetContents accepts at most 20 URLs per request.
• API errors are caught and returned as friendly string messages.
• Requires a valid Exa API key.

Exa API

These tools use the Exa API. Exa offers a free tier to get started.
