## 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 perp-funding-rate-cross-exchange-snapshot-829d8b7e
```

Example prompt: What's the current perpetual futures funding rate for ETH on Binance, OKX, and Bybit — give me the annualised rate, mark price, and Bybit's open interest and long/short ratio.

## When to prefer this

Use this endpoint when you need a quick, cross-exchange snapshot of the current funding rate for a single coin in USDT-margined perpetual futures markets. It is ideal for spot-checking carry costs, gauging market sentiment via the long/short ratio, or identifying funding rate discrepancies across Binance, OKX, and Bybit. It is not suitable for historical funding rate analysis, time-series charting, or monitoring multiple coins simultaneously in one call.

## Known failure modes

- Invalid or unrecognised ticker symbol returns an error or empty data
- Upstream exchange API unavailability may result in missing rows or stale data
- Symbols with no perpetual futures market on one or more exchanges will have null/missing fields for those exchanges
- Ticker must be 2–10 letters (e.g. BTC); full trading pair notation (e.g. BTCUSDT) may not be accepted

## How this service works

Current perpetual-futures funding rate for one coin (USDT-margined) on Binance, OKX and Bybit, with each rate annualised (3 payments a day), mark price, and from Bybit: open interest value and the long/short account ratio. A table of exchanges, not a time-series heatmap; funding history is not included.

## Output

A table (one row per exchange: Binance, OKX, Bybit) containing the raw current funding rate, the annualised rate (assuming 3 payments per day), and the mark price for each exchange. For Bybit specifically, the response also includes open interest value and the long/short account ratio.
