## 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-accumulated-funding-rate-lookup-660c0a03
```

Example prompt: What's the accumulated funding rate for crypto futures right now? Pull the latest data from CoinAnk — I want to see how much funding has piled up.

## When to prefer this

Use this endpoint when you need accumulated (cumulative) funding rate data for crypto perpetual futures without signing up for an API key, and you are comfortable paying $0.002 USDC per call via the x402 micropayment protocol. Prefer this over traditional REST APIs when operating in an agent workflow that supports x402 wallet-based payments.

## Known failure modes

- Payment not received or insufficient USDC results in 402 Payment Required
- Invalid or missing 'type' query parameter returns an error response
- Empty data array returned if no accumulated funding data is available for the requested type
- Network or upstream CoinAnk API unavailability causes timeout or 5xx error
- Malformed request body triggers schema validation failure
