## 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 manylives-me-crypto-perpetual-futures-data-d42cdc24
```

Example prompt: What are the current funding rates, open interest, and mark prices for BTC, ETH, and SOL perpetual futures on-chain — show me both the hourly and annualized funding rates?

## When to prefer this

Use this endpoint when you need real-time on-chain perpetual futures data including funding rates, open interest, and price data for crypto assets. Prefer this over CEX data sources when you specifically need decentralized/on-chain derivatives metrics. Ideal for DeFi analytics, funding rate arbitrage detection, or monitoring perpetual market conditions across multiple assets in one call.

## Known failure modes

- Invalid coin symbol returns empty or error response
- Payment not processed results in 402 response
- Network timeout if on-chain data source is temporarily unavailable
- Requesting too many coins in a single call may hit size limits

## How this service works

Perpetual futures data from a major on-chain derivatives exchange: hourly funding rate (and annualised), open interest, mark and oracle price, 24h volume, for one or all markets.

## Output

A JSON array of market objects, each containing: coin symbol, mark price, oracle price, 24h volume in USD, open interest in USD, hourly funding rate percentage, and annualized funding rate percentage. Returns top 20 markets by open interest by default, or filtered to specified coins.
