## 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 perp-derivatives-signals-snapshot-880246f0
```

Example prompt: Pull the full Hyperliquid perp snapshot for BTC — I want the mark price, 24h move, annualized funding rate, open interest, volume, and any risk flags right now.

## When to prefer this

Use this endpoint when you need a comprehensive single-call market snapshot for one Hyperliquid perpetual — combining price, funding, OI, volume, leverage, and risk flags in one response. Prefer it over separate calls when you want a holistic view with pre-computed flags and a human-readable verdict, rather than fetching individual metrics from sibling endpoints.

## Known failure modes

- Invalid or unknown coin ticker returns null fields or error response
- Coin not listed on Hyperliquid returns empty or degraded snapshot
- Hyperliquid data feed temporarily unavailable triggers degraded=true with partial data
- Rate limiting or payment failure (x402) results in 402 Payment Required response
- Malformed query parameter returns 400-level error

## How this service works

One-call perp snapshot on Hyperliquid: price, 24h move, funding, open interest, volume and max leverage with flags.

## Output

A JSON object containing: coin ticker, mark price, oracle price, 24h percentage change, annualized funding rate, open interest in USD, 24h volume in USD, max leverage, an array of risk flags, a human-readable verdict and summary, thresholds used for flag logic, timestamp (asOf), source URL, and a degraded indicator if data quality was reduced.
