The Hyperliquid info endpoint with `type: "maxMarketOrderNtls"` is used to fetch the maximum market-order notional for each leverage bucket.

<Tip>
  Estimate your monthly cost for this API using the [Pricing Calculator](/docs/pricing-calculator?endpoint=%2Fapi-reference%2Fhyperliquid-info%2Fmax-market-order-ntls).
</Tip>

<Info>
  * Wire-equal to `POST api.hyperliquid.xyz/info` with `{"type": "maxMarketOrderNtls"}`.
  * Each entry is a `[leverage, maxNotionalUsd]` tuple; the notional is a decimal string.
  * This is a global, non-user-keyed type. Buckets are ordered from highest leverage to lowest.
</Info>

Returns the maximum market-order notional permitted at each leverage bucket. Each element is a `[maxLeverage, maxNotional]` tuple: a position running at up to `maxLeverage` may place a single market order of at most `maxNotional` USD. The cap tightens as leverage rises, bounding slippage on aggressive market orders.

## Endpoint

```
POST https://hypercore.goldrushdata.com/info
Authorization: Bearer <GOLDRUSH_API_KEY>
Content-Type: application/json
```

## Request

<ParamField body="type" type="string" required>
  Always `"maxMarketOrderNtls"`.
</ParamField>

### Example

<CodeGroup>
  ```bash cURL theme={null}
  curl -X POST https://hypercore.goldrushdata.com/info \
    -H "Authorization: Bearer $GOLDRUSH_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "type": "maxMarketOrderNtls"
    }'
  ```

  ```typescript TypeScript theme={null}
  const response = await fetch("https://hypercore.goldrushdata.com/info", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.GOLDRUSH_API_KEY}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      type: "maxMarketOrderNtls",
    }),
  });

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

  ```python Python theme={null}
  import os, requests

  response = requests.post(
      "https://hypercore.goldrushdata.com/info",
      headers={"Authorization": f"Bearer {os.environ['GOLDRUSH_API_KEY']}"},
      json={"type": "maxMarketOrderNtls"},
  )

  max_ntls = response.json()
  ```
</CodeGroup>

## Response

An array of `[maxLeverage, maxNotional]` tuples, ordered from highest leverage to lowest.

```json theme={null}
[
  [25, "30000000.0"],
  [20, "5000000.0"],
  [10, "2000000.0"],
  [1, "500000.0"]
]
```

### Field descriptions

<Note>
  The notional value in each tuple is returned as a **decimal string**, preserving upstream precision. Do not parse it as a float - keep it as a string or use a fixed-precision decimal type.
</Note>

<ResponseField name="[n]" type="[int, string]">
  A `[maxLeverage, maxNotional]` tuple. Index `0` is the maximum leverage (int) that the bucket applies to; index `1` is the maximum market-order notional in USD for that bucket, as a decimal string.
</ResponseField>
