# TypeScript SDK

> Wire the Sector8 Guard Module into your Node.js or TypeScript application

<Info>The TypeScript SDK is in active development. For early access contact [support@sector8.ai](mailto:support@sector8.ai). In the meantime, use the [REST API](/api-reference/overview) directly.</Info>

## Coming soon

```bash theme={null}
npm install @sector8/sdk
```

```typescript theme={null}
import { GuardClient, ToolCallRequest } from '@sector8/sdk';

const client = new GuardClient({
  apiKey: process.env.SECTOR8_API_KEY,
  clientId: process.env.SECTOR8_CLIENT_ID,
});

const result = await client.evaluate({
  toolName: 'bash',
  arguments: { command: 'ls -la' },
  sessionId: 'session-abc123',
});

if (result.decision === 'DENY') {
  console.log('Blocked:', result.reasonCode);
  console.log('Evidence hash:', result.evidenceHash);
}
```

## Use the REST API now

While the SDK is in development, you can use the [REST API](/api-reference/overview) directly from any Node.js application:

```typescript theme={null}
const response = await fetch('https://api.sector8.ai/v1/evaluate', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.SECTOR8_API_KEY}`,
    'X-Client-ID': process.env.SECTOR8_CLIENT_ID,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    tool_name: 'bash',
    arguments: { command: 'ls -la' },
    session_id: 'session-abc123',
  }),
});

const decision = await response.json();
```
