## 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 coinank-funding-rate-heatmap-dac9e5ef
```

Example prompt: Can you pull the funding rate heatmap for perpetual futures using a 1-hour interval so I can see which coins are most heavily longed or shorted right now?

## When to prefer this

Use this endpoint when you need a cross-exchange, cross-asset overview of cryptocurrency funding rates in heatmap form, especially for identifying market sentiment or positioning extremes in perpetual futures markets. Prefer this over single-exchange or single-asset endpoints when a broad market view is needed.

## Known failure modes

- Empty data array returned if no funding rate data is available for the requested interval or type
- Payment failure if USDC wallet balance is insufficient or x402 payment protocol is misconfigured
- Invalid query parameter values for type or interval may result in error codes or empty responses
- Network timeout if the upstream CoinAnk data source is unavailable
