## 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 hyperliquid-account-open-orders-8bcb2af0
```

Example prompt: Show me all the resting open orders for the Hyperliquid account 0x1234567890abcdef1234567890abcdef12345678 — I want to see each order's coin, side, limit price, and size.

## When to prefer this

Use this endpoint when you need to inspect the current resting (unfilled) limit orders for a specific Hyperliquid account, including frontend metadata like order type and trigger. Prefer this over order history endpoints when you need live pending orders rather than filled trade history.

## Known failure modes

- Invalid or malformed 0x address returns a validation error
- Address with no open orders returns count:0 and empty orders array
- Hyperliquid upstream unavailable causes a relay failure
- Missing required address query parameter returns an error
- Non-hex characters in address fail the regex pattern check

## How this service works

A Hyperliquid account's resting open orders with frontend metadata, for any 0x address.

## Output

Returns a JSON object containing the queried address (lowercased), the timestamp of the query, a count of open orders, and a verbatim array of frontendOpenOrders from Hyperliquid — each order includes coin symbol, side (buy/sell), limit price, size, order type, trigger conditions, and timestamp.
