]);

Advanced Options:

// Specific provider
$response = apply_filters('ai_request', $request, 'anthropic');

// With streaming

// With tools
$response = apply_filters('ai_request', $request, null, null, $tools);

Providers

Dynamic model fetching from provider APIs:

• OpenAI - GPT models, streaming, function calling, Files API

• Self-Contained: Providers handle own formatting
• Shared Storage: Efficient API key management
• WordPress-Native: HTTP API, options, admin patterns
• Extensible: Third-party provider registration

Multi-Plugin Support

• Plugin-isolated configurations
• Shared API key storage
• No provider conflicts
• Independent AI settings

Components

• Filter-based provider discovery
• Self-contained provider classes
• Admin interface via ai_render_component
• Centralized API key storage

Core Filters

// Provider Discovery
$providers = apply_filters('ai_providers', []);

// API Keys
$keys = apply_filters('ai_provider_api_keys', null);

// Models
$models = apply_filters('ai_models', $provider, $config);

// Tools
$tools = apply_filters('ai_tools', []);

// Admin UI
echo apply_filters('ai_render_component', '', $config);

Multi-Plugin Configuration

Plugin-Isolated Settings:

ai_http_client_providers_myplugin = [
    'openai' => ['model' => 'gpt-4', 'temperature' => 0.7]
];

Shared API Keys:

ai_http_client_shared_api_keys = ['openai' => 'sk-...'];

AI Tools System

Registration:

add_filter('ai_tools', function($tools) {
    $tools['file_processor'] = [
        'class' => 'FileProcessor_Tool',
        'category' => 'file_handling',
        'description' => 'Process files and extract content',
        'parameters' => ['file_path' => ['type' => 'string', 'required' => true]]
    ];
    return $tools;
});

Discovery & Usage:

$all_tools = apply_filters('ai_tools', []);
$result = ai_http_execute_tool('file_processor', ['file_path' => '/path']);

Distribution

• Composer package installation

• No external dependencies
• Version conflict resolution
• Multiple plugin support

Adding Providers

class AI_HTTP_MyProvider {
    public function request($request) { /* ... */ }
