Session Management - Synthra

Synthra provides isolated conversation contexts called sessions. Each session maintains its own message history, context window, and token usage tracking.

Quick Start

const agent = new SynthraAgent({
  apiKey: process.env.SYNTHRA_API_KEY
});

// Create session
const session = agent.createSession('user_abc123def456');

// Send message
const response = await agent.sendMessage(
  session.id,
  'Hello, Synthra!'
);

// Delete session
await agent.deleteSession(session.id);

Session Limits

Tier	Max Sessions	Max Messages	Context Window
Free	10	100	4,096 tokens
Pro	100	1,000	8,192 tokens
Enterprise	Unlimited	Unlimited	32,768 tokens

Lifecycle

Sessions automatically expire after 24 hours of inactivity. States: Created → Active → Idle → Expired

Configuration

const session = agent.createSession('user_abc123def456', {
  metadata: {
    source: 'web',
    language: 'en'
  },
  contextConfig: {
    maxTokens: 8192,
    compressionEnabled: true,
    retentionPolicy: 'semantic'
  }
});

Error Handling

try {
  const response = await agent.sendMessage(session.id, 'Hello!');
} catch (error) {
  if (error.code === 'session_not_found') {
    console.log('Session expired or deleted');
  }
}

Sessions are automatically compressed when approaching token limits.

Deleted sessions cannot be recovered. Use clearSession() to reset history while preserving the session.
