# perpConciseAnnotations | Hyperliquid info

> The info endpoint with type: "perpConciseAnnotations" returns concise annotations (category, display name, keywords) for all perpetual assets.

<Info>
  This method is available on Chainstack. Not all Hyperliquid methods are available on Chainstack, as the open-source node implementation does not support them yet — see [Hyperliquid methods](/docs/hyperliquid-methods) for the full availability breakdown.
</Info>

The `info` endpoint with `type: "perpConciseAnnotations"` returns concise annotations for all perpetual assets. Each annotation classifies a perpetual into a category and can carry a frontend display name and search keywords. Use this method to categorize and label perpetual markets in dashboards and search interfaces.

## Parameters

### Request body

* `type` (string, required) — The request type. Must be `"perpConciseAnnotations"`.

## Response

Returns an array of `[coin, annotation]` tuples. Each annotation object contains:

* `category` (string) — The classification category assigned to the perpetual.
* `displayName` (string, optional) — A display name for frontends to use instead of the L1 name.
* `keywords` (array of strings, optional) — Keywords used as hints to match against searches.

## Example request

<CodeGroup>
  ```shell Shell theme={null}
  curl -X POST \
    -H "Content-Type: application/json" \
    -d '{"type": "perpConciseAnnotations"}' \
    https://hyperliquid-mainnet.core.chainstack.com/4f8d8f4040bdacd1577bff8058438274/info
  ```

  ```python Python (hyperliquid-python-sdk) theme={null}
  from hyperliquid.info import Info

  # skip_ws=True avoids opening a WebSocket connection for this REST call
  info = Info("YOUR_CHAINSTACK_ENDPOINT", skip_ws=True)

  # The SDK has no dedicated perpConciseAnnotations helper, so post the request directly.
  perp_concise_annotations = info.post("/info", {"type": "perpConciseAnnotations"})
  print(perp_concise_annotations)
  ```

  ```typescript TypeScript (@nktkas/hyperliquid) theme={null}
  import { HttpTransport, InfoClient } from "@nktkas/hyperliquid";

  // apiUrl points the transport at a custom server (your Chainstack endpoint)
  const transport = new HttpTransport({ apiUrl: "YOUR_CHAINSTACK_ENDPOINT" });
  const info = new InfoClient({ transport });

  const perpConciseAnnotations = await info.perpConciseAnnotations();
  console.log(perpConciseAnnotations);
  ```
</CodeGroup>

<Note>
  **Use your own endpoint in your code.** The code examples use a placeholder Chainstack endpoint (YOUR\_CHAINSTACK\_ENDPOINT) — replace it with your own Hyperliquid node endpoint from the [Chainstack console](https://console.chainstack.com/). The curl above uses a shared public endpoint for quick checks only; do not use it in production.
</Note>

## Example response

```json theme={null}
[
  ["flx:BTC", { "category": "crypto" }],
  ["flx:COIN", { "category": "stocks" }],
  ["flx:GOLD", { "category": "commodities" }]
]
```

## Use cases

The `info` endpoint with `type: "perpConciseAnnotations"` is useful for:

* Grouping perpetual markets by category in dashboards and market screens
* Showing frontend-friendly display names instead of raw L1 names
* Powering search and filtering with per-asset keywords
