The Hyperliquid info endpoint with `type: "metaAndAssetCtxs"` is used to fetch the full Hyperliquid perpetuals market universe with live per-asset trading context.

<Tip>
  Estimate your monthly cost for this API using the [Pricing Calculator](/pricing-calculator?endpoint=%2Fapi-reference%2Fhyperliquid-info%2Fmeta-and-asset-ctxs).
</Tip>

<Info>
  * Wire-equal to `POST api.hyperliquid.xyz/info` with `{"type": "metaAndAssetCtxs"}`.
  * For real-time mark-price updates, use the <a href="https://goldrush.dev/docs/api-reference/streaming-api/subscriptions/ohlcv-pairs-stream" target="_blank" rel="noopener noreferrer">Streaming API OHLCV streams</a> instead of polling.
</Info>

Returns a tuple `[meta, assetCtxs[]]` covering the entire Hyperliquid perpetuals universe - every coin’s metadata plus a live snapshot of mark price, funding rate, open interest, and 24-hour volume.

This is a global, non-user-keyed type. A single cache entry is shared across all callers and is refreshed continuously from upstream Hyperliquid.

## Endpoint

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

## Request

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

<ParamField body="dex" type="string">
  HIP-3 builder DEX identifier. Empty string (default) returns the canonical Hyperliquid perp universe. Pass a builder code (e.g. `"xyz"`) to query a HIP-3 deployer's universe.
</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": "metaAndAssetCtxs",
      "dex": ""
    }'
  ```

  ```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: "metaAndAssetCtxs",
      dex: "",
    }),
  });

  const [meta, assetCtxs] = 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": "metaAndAssetCtxs", "dex": ""},
  )

  meta, asset_ctxs = response.json()
  ```
