## 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 dollarchase-extract-perpetual-funding-rates-f799f95d -d '<json body>'
```

Example prompt: Pull the current perpetual funding rates for BTC across Binance, Bybit, Hyperliquid, dYdX, and Kraken, and show me the cross-exchange highs and lows with any bad data filtered out.

## When to prefer this

Choose this endpoint when you need aggregated, cross-validated perpetual funding rate data from multiple top exchanges in a single call, especially when data quality matters — it applies outlier detection and hygiene so you don't need to clean raw exchange data yourself. Prefer it over querying individual exchange APIs when you want cross-exchange extremes or funding rate arbitrage signals.

## Known failure modes

- Unsupported or invalid symbol returns an error or empty result
- One or more exchanges temporarily unavailable may reduce coverage
- Stale data if exchange APIs are lagging
- Payment failure (402) if USDC balance is insufficient
