## 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-funding-rate-extremes-leaderboard-fda00549
```

Example prompt: What are the most extreme funding rates on Hyperliquid right now — show me which perpetuals have the highest and lowest carry costs so I can spot funding arb opportunities?

## When to prefer this

Use this endpoint when you specifically need a ranked, consolidated view of Hyperliquid funding rate extremes across all perpetual markets in a single call, rather than querying individual market funding rates one by one. Ideal for carry-trade screening, funding arbitrage detection, and monitoring which assets have the most extreme funding on Hyperliquid DEX.

## Known failure modes

- Hyperliquid API unavailable — upstream data fetch fails, returning a 5xx error
- Payment not included or insufficient — x402 payment required error returned
- Rate limit exceeded — too many requests in a short window
- Empty or stale data if Hyperliquid funding data has not refreshed recently
