## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pa1m-hyperliquid-orderbook-d077c0c6
```

Example prompt: What does the current order book look like for BTC on Hyperliquid perpetuals — show me the price levels and sizes on both the bid and ask side.

## When to prefer this

Use this endpoint when you need real-time Hyperliquid-specific perpetuals order book data — particularly when you care about the exact Hyperliquid venue (rather than aggregated multi-exchange data), need per-level price and size detail for slippage estimation, or are building trading logic that executes directly on Hyperliquid.

## Known failure modes

- Invalid or unsupported coin symbol returns an error or empty levels array
- Payment of 0.001 USDC not provided results in HTTP 402 Payment Required
- Network latency may cause slightly stale data in fast-moving markets
- Hyperliquid exchange downtime results in upstream unavailability
