# Polymarket: Get Order Book

> Reading the full bid and ask depth for one outcome token to judge liquidity. Includes SDK V2 examples, input constraints, response fields, and Deepline cost.

Reading the full bid and ask depth for one outcome token to judge liquidity.

<Info>
  Tool ID: `polymarket_get_order_book`
</Info>

## Run this action

Use the TypeScript SDK for a single call. Put `ctx.tools.execute(...)` inside a Play when the call should be durable, scheduled, or run across a CSV.

```ts theme={null}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'polymarket_get_order_book',
  {
    "token_id": "token_123"
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={null}
deepline tools execute polymarket_get_order_book --input '{
  "token_id": "token_123"
}' --json
```

## Example response

The SDK exposes this shape at `result.toolResponse.raw`. Values below are representative.

```json theme={null}
{
  "data": {
    "market": "example",
    "asset_id": "asset_123",
    "timestamp": "example",
    "hash": "example",
    "bids": [
      {
        "price": "example",
        "size": "example"
      }
    ],
    "asks": [
      {
        "price": "example",
        "size": "example"
      }
    ],
    "min_order_size": "example",
    "tick_size": "example",
    "neg_risk": true,
    "last_trade_price": "example"
  }
}
```

Use `deepline tools get polymarket_get_order_book --json` for the latest machine-readable contract.
