Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-funding-extremes-ca11c6bb
```

Example prompt: Show me the top 7 most crowded longs and shorts on Hyperliquid perps right now, only including coins with at least $5 million in open interest.

## When to prefer this

Use this endpoint when you need a broad market scan of funding extremes across all Hyperliquid perps at once, rather than querying a single coin. Prefer this over per-coin funding endpoints when the goal is to discover which assets currently have the most crowded positioning — ideal for contrarian trade signals, regime detection, or risk monitoring dashboards. The open interest filter makes it especially useful for ignoring low-liquidity noise.

## Known failure modes

- No coins meet the minimum OI threshold — returns empty lists
- Hyperliquid data feed degraded — response may include degraded:true flag
- Invalid n parameter (outside 1–10 range) — may return error or default
- Temporary upstream data unavailability — stale or null asOf timestamp
- Rate limit or payment failure — 402 or 429 response

## How this service works

Most extreme perp funding right now across Hyperliquid, filtered by open interest. Top crowded longs and shorts.

## Output

Returns two ranked lists — top crowded longs and top crowded shorts — each containing coin symbol, annualized funding rate (%), open interest in USD, and 24h volume in USD. Also includes a summary verdict, thresholds used to classify 'crowded', total coins scanned, minimum OI filter applied, an asOf timestamp, and an optional degraded flag if data quality is reduced.
