## 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-hip-3-mark-price-quality-check-7d8850b2
```

Example prompt: Check the mark price quality for the HIP-3 perp market on Hyperliquid — I need to know if the current mark price is trustworthy, what the divergence from the oracle is in bps, and whether it's labeled clean or elevated risk.

## When to prefer this

Use this endpoint when you need to assess the reliability of Hyperliquid HIP-3 perpetual market prices before trading or quoting, especially for markets with deployer-controlled oracles where subtle mispricing may not be caught by validator threshold flags. Prefer over generic price feeds when the question is specifically about mark price trustworthiness or liquidity quality on HIP-3 markets.

## Known failure modes

- Unknown or invalid symbol returns an error or empty result
- HIP-3 market data temporarily unavailable causes a fetch failure
- Payment not processed results in 402 response
- Request without required x402 payment header rejected

## How this service works

Trust score for Hyperliquid HIP-3 perp prices. Answers "can I rely on this mark now", "which HIP-3 markets are mispriced or too thin to trade". Each market runs its own deployer oracle and validators only flag >50% moves, so subtler mispricing slips through. Per market: mark-vs-oracle divergence in bps, open interest, a 0-100 quality score and a clean/watch/elevated/high_risk label weighting divergence by liquidity. Omit symbol to scan the riskiest markets. Deterministic, no LLM.

## Output

Returns per-market data including mark-vs-oracle price divergence in basis points, open interest, a 0-100 quality score, and a categorical risk label (clean, watch, elevated, or high_risk). If no symbol is provided, returns a scan of the riskiest HIP-3 markets across the platform.
