## 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 funding-rate-analyzer-794bd413 -d '<json body>'
```

Example prompt: What are the current and historical funding rates for ETH on Hyperliquid, assuming a $25,000 long position, and show me a 168-hour cash-flow illustration of what I'd pay or receive?

## When to prefer this

Choose this endpoint when you need perpetual futures funding rate data specifically for Hyperliquid markets (up to six markets covered), including both current and historical rates, and want funding amounts expressed in dollar terms for a given notional size. It is especially useful when you want long vs. short funding comparison or a time-based cash-flow illustration. Prefer this over general market data APIs when the goal is to quantify the carry cost or income of a Hyperliquid perp position.

## Known failure modes

- Unknown or unsupported asset returns an error or uncharged response
- Current funding data unavailable — report is returned but no charge is applied
- Incomplete historical data — disclosed in the response rather than silently omitted
- Invalid notional amount (zero or malformed) rejected by schema validation
- Unsupported target environment (non-Hyperliquid mainnet) rejected
- Illustration duration outside 1–720 hour range returns a validation error
