# webData2 | Hyperliquid info
> The info endpoint with type: "webData2" returns aggregate information about a user for frontend consumption. Hyperliquid info via Chainstack.
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.
The `info` endpoint with `type: "webData2"` returns aggregate information about a user for frontend consumption. It is primarily a convenience aggregation used by web clients.
## Parameters
### Request body
* `type` (string, required) — The request type. Must be `"webData2"`.
* `user` (string, required) — Address in 42-character hexadecimal format (e.g., `0x31ca8395cf837de08b24da3f660e77761dfb974b`).
## Response
The response is a large object with user‑centric aggregates for frontend use (exact fields may change). Typical categories include:
* user overview and balances
* open orders and positions summaries
* recent fills and funding
* selected UI/runtime configuration for the client
### Understanding web data aggregation
**Data optimization:**
* Combines multiple data sources into a single efficient endpoint
* Reduces the number of API calls required for web applications
* Provides pre-aggregated statistics for improved performance
* Optimized for frontend consumption and display
**Real-time updates:**
* Market data reflects current trading conditions
* Network statistics show live platform activity
* UI configuration allows for dynamic feature management
* Data freshness ensures accurate user experience
**Frontend integration:**
* Structured for easy consumption by web applications
* Includes display-ready formatted data
* Supports responsive UI updates and notifications
* Enables comprehensive dashboard implementations
**Performance benefits:**
* Single endpoint reduces latency and bandwidth usage
* Pre-calculated aggregations improve response times
* Efficient data structure minimizes parsing overhead
* Optimized for high-frequency frontend updates
## Example request
```shell Shell theme={"system"}
curl -X POST \
-H "Content-Type: application/json" \
-d '{"type": "webData2"}' \
https://hyperliquid-mainnet.core.chainstack.com/4f8d8f4040bdacd1577bff8058438274/info
```
```python Python (hyperliquid-python-sdk) theme={"system"}
from hyperliquid.info import Info
# In the official Python SDK, webData2 is a WebSocket subscription,
# not an HTTP info method, so the WebSocket manager must stay enabled.
info = Info("YOUR_CHAINSTACK_ENDPOINT")
user = "0x31ca8395cf837de08b24da3f660e77761dfb974b"
info.subscribe({"type": "webData2", "user": user}, print)
```
```typescript TypeScript (@nktkas/hyperliquid) theme={"system"}
import * as hl from "@nktkas/hyperliquid";
const transport = new hl.HttpTransport({ apiUrl: "YOUR_CHAINSTACK_ENDPOINT" });
const client = new hl.InfoClient({ transport });
const data = await client.webData2({
user: "0x31ca8395cf837de08b24da3f660e77761dfb974b",
});
console.log(data);
```
**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.
## Use case
The `info` endpoint with `type: "webData2"` is essential for applications that need to:
* **Trading dashboards**: Display comprehensive market overview and statistics
* **Web applications**: Provide aggregated data for frontend interfaces
* **Market summaries**: Show platform-wide trading activity and metrics
* **Real-time displays**: Update UI components with current market conditions
* **Performance monitoring**: Track network health and user activity
* **Feature management**: Control UI features based on configuration settings
* **Mobile applications**: Efficiently load dashboard data with minimal requests
* **Analytics interfaces**: Display aggregated platform statistics
* **Status pages**: Show platform health and maintenance information
* **Portfolio overviews**: Provide market context for user positions
* **Trading terminals**: Display comprehensive market data in trading interfaces
* **Public displays**: Show platform statistics for marketing and transparency
* **API optimization**: Reduce multiple endpoint calls with single aggregated request
* **Caching strategies**: Implement efficient data caching for web applications
This endpoint is particularly valuable for web developers building comprehensive trading interfaces, mobile app developers optimizing for performance, dashboard creators needing aggregated platform data, and any application requiring efficient access to multiple data categories in a single API call on the Hyperliquid network.
