# Developer Docs

Trade Strix Lab programmatically — a typed TypeScript SDK over a REST + WebSocket order-book API.

Strix Lab runs a central-limit order book. Orders match off-chain in milliseconds and settle on-chain in USDC — and everything the app does, your code can do too.

There are two ways in:

* [**`strix-sdk`**](/get-started/installation.md) — the official TypeScript client. Typed responses, HMAC signing, order-book caching, and auto-reconnecting WebSocket channels. **Start here.**
* [**The raw HTTP + WebSocket API**](/http-and-websocket-api/rest.md) — for any other language. The SDK is a thin wrapper over it, so everything below maps one-to-one.

{% hint style="success" %}
**Never used the platform before?** Read [Core Concepts](/get-started/concepts.md) first — five minutes there saves an afternoon of debugging `tokenId`.
{% endhint %}

### Hello, order book

{% code title="hello-strix.ts" %}

```ts
import { StrixClient } from 'strix-sdk';

const client = new StrixClient({ baseUrl: 'https://api.strixlab.io/api' });

const { items } = await client.events.list({ status: 'open', limit: 1 });
const tokenId   = items[0].markets[0].outcomes[0].tokenId;

const book = await client.orderbook.snapshot(tokenId, { depth: 5 });
console.log(book.bids[0], book.asks[0]);
```

{% endcode %}

No credentials needed for that — market data is public. Add API keys when you want to trade.

**Availability.** Opening new positions is not available in every jurisdiction. See [Restricted Regions](https://docs.strixlab.io/policies/restricted-regions) before you deploy a bot.
