🔌 API Methods

Provider Management

// Get all providers
await window.electron.invoke('ai:get-providers');

// Get provider presets
await window.electron.invoke('ai:get-available-presets');

// Add provider from preset (one-click!)
await window.electron.invoke('ai:add-provider-from-preset', 'OpenCode Zen (OpenAI-compatible)', 'api-key');

// Fetch models from provider API
await window.electron.invoke('ai:fetch-models', providerId);

// Test connection
await window.electron.invoke('ai:test-connection', providerId);

Settings Management

// Get AI settings
const items = await window.electron.invoke('storage:get-items');

// Update settings
await window.electron.invoke('storage:update-items', {
  'aiProvider': providerId,
  'aiModel': 'gpt-4o',
  'aiTemperature': '0.7',

});

💡 Usage Examples

Adding a Provider from Preset

Option 1: Via GUI

1. Open AI Provider Settings
2. Click "Add from Preset"
3. Select provider (e.g., "OpenCode Zen")
4. Enter API key
5. Click "Add Provider"

Option 2: Via Code

const provider = await window.electron.invoke('ai:add-provider-from-preset', 
  'OpenCode Zen (OpenAI-compatible)', 
  'your-api-key'
);

Fetching Models from Provider

const models = await window.electron.invoke('ai:fetch-models', providerId);
console.log(`Found ${models.length} models:`, models);

Testing Connection

const result = await window.electron.invoke('ai:test-connection', providerId);
if (result.success) {
  console.log('✅ Connected successfully!');
} else {
  console.log('❌ Connection failed:', result.message);
}
