## 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 x402stock-hip-3-dex-markets-0772e3f0
```

Example prompt: What are all the markets, funding rates, open interest, and 24h volume on the Hyperliquid HIP-3 builder DEX with ID 'xyz'?

## When to prefer this

Use this endpoint when you need real-time synthetic perpetual market data — including funding rates, open interest, and volume — for equity, commodity, FX, or index perps on a specific Hyperliquid HIP-3 builder DEX. Prefer this over generic crypto price feeds when the user specifically needs HIP-3 synthetic perp data, funding APRs, or on-chain perpetual market statistics that are not available on centralized exchanges.

## Known failure modes

- Invalid or unknown dex ID returns an error or empty result
- DEX ID not found — use /api/v1/hip3/dexs to list valid DEX IDs
- Payment not processed (402) — USDC payment required per call
- Network or upstream Hyperliquid data unavailability causing stale or missing data
- Malformed path parameter causes a 400 or 404 response

## How this service works

All markets in one Hyperliquid HIP-3 builder DEX (pass the dex id, e.g. `xyz`): 24/7 synthetic mark & oracle price, funding rate + APR, open interest, and day volume each. Covers equity perps (NVDA, TSLA), commodities (GOLD, BRENTOIL, COPPER), FX, and index perps. Oracle-priced proxies carrying funding — not the underlying's official last trade. List DEXs at /api/v1/hip3/dexs. From x402stock

## Output

Returns a list of all synthetic perpetual markets on the specified HIP-3 builder DEX. Each market includes the symbol (e.g. NVDA, TSLA, GOLD, BRENTOIL, FX pairs, index), 24/7 synthetic mark price, oracle price, current funding rate, annualized funding APR, open interest, and 24-hour trading volume. These are oracle-priced synthetic proxies carrying funding, not the underlying asset's official last trade price.
