# Node SDK

> Use AgentLine from TypeScript / JavaScript.

# Node SDK

```bash theme={null}
npm i agentline
```

```typescript theme={null}
import { AgentLineClient } from "agentline";

const client = new AgentLineClient({ apiKey: "al_live_..." });
```

## Resources

The client is grouped by resource, mirroring the [API Reference](/api-reference):

```typescript theme={null}
client.agents     // create, list, get, update, delete
client.numbers    // buy, list, get, reassign
client.calls      // create, list, get, getTranscript, hangup, pushContext
client.messages   // send, list, listConversations
client.events     // poll, peek
client.webhooks   // list, set, delete, test
client.billing    // getBalance, getExpenditure, getSummary, ...
client.voice      // list, get, set, reset
```

## End-to-end example

```typescript theme={null}
import { AgentLineClient } from "agentline";

const client = new AgentLineClient({ apiKey: "al_live_..." });

const agent = await client.agents.create({
    name: "Support Bot",
    systemPrompt: "You are a helpful assistant.",
    initialGreeting: "Hello! How can I help you today?",
});
await client.numbers.buy({ agentId: agent.id, country: "US", areaCode: "415" });

const call = await client.calls.create({ agentId: agent.id, toNumber: "+12125557890" });
await client.calls.hangup(call.id);

console.log(await client.calls.getTranscript(call.id));
```

The SDK is generated from the same OpenAPI spec as this API reference, so the
SDK and docs always match. Works on Node 18+, Vercel, Cloudflare Workers, Deno,
Bun, and React Native.
