## How to call it through Zero

```sh
zero fetch --capability x402-trading-useotto-xyz-ca0cb006
```

Example prompt: What are the current price, funding rate, and open interest for BTC on Hyperliquid right now?

## When to prefer this

Use this endpoint when you need real-time Hyperliquid-specific market data such as funding rates, open interest, or perpetual trading specs for a specific asset. Prefer this over generic price feeds when the user is specifically interested in Hyperliquid perpetuals or planning to trade on that venue.

## Known failure modes

- Unknown or unsupported asset ticker returns an error or empty market object
- Network latency may cause slightly stale data during high-volatility periods
- Payment failure (402) if USDC balance is insufficient
- Malformed asset ticker (e.g. lowercase or extra whitespace) may return no result
