The Hyperliquid info endpoint with `type: "activeAssetData"` is used to fetch a user's active trading limits, leverage setting, available size, and mark price for a single Hyperliquid perpetual asset.

> [!TIP]
>
> Estimate your monthly cost for this API using the [Pricing Calculator](https://goldrush.dev/docs/pricing-calculator.md?endpoint=%2Fapi-reference%2Fhyperliquid-info%2Factive-asset-data).

> [!NOTE]
>
> * Wire-equal to `POST api.hyperliquid.xyz/info` with `{"type": "activeAssetData", "user": "...", "coin": "ETH"}`.
> * `coin` accepts the Hyperliquid asset identifier for the target perp market. For HIP-3 markets, pass the same dex-qualified coin string used by Hyperliquid for that asset.
> * `maxTradeSzs` and `availableToTrade` are returned as two directional decimal-string values. Preserve the upstream array order and use fixed-precision decimal handling.
> * For whole-account position and margin state, use `clearinghouseState`; this endpoint is scoped to one user and one active asset.

Returns per-user, per-asset trading state for one active perpetual market: the user's leverage setting, directional max trade sizes, directional available-to-trade amounts, and the current mark price.

User-keyed and coin-keyed. Use this when a trading UI needs to show how much size a wallet can open or close on a specific asset before placing an order. For full account margin and open positions, use [clearinghouseState](https://goldrush.dev/docs/api-reference/hyperliquid-info/clearinghouse-state.md); for market metadata and asset context, use [metaAndAssetCtxs](https://goldrush.dev/docs/api-reference/hyperliquid-info/meta-and-asset-ctxs.md).

## Endpoint

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

## Request

**type** `string` *required* (default: activeAssetData)

Always `"activeAssetData"`.

**user** `string` *required*

The wallet address (lowercase 0x-prefixed hex).

**coin** `string` *required*

The perp asset identifier, e.g. `"ETH"` or `"APT"`. For HIP-3 markets, pass the same dex-qualified coin string used by Hyperliquid for that asset.

### Example

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

});

const activeAsset = 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": "activeAssetData",

        "coin": "APT",
    },
)

active_asset = response.json()

## Response

A single JSON object with the user's active trading configuration and directional trading capacity for the requested asset.

```json theme={null}
