## 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 perpetual-funding-rate-radar-multi-venue-comparison-6f99a8e3
```

Example prompt: Show me a cross-venue funding rate comparison for the BTC perpetual across Hyperliquid, dYdX, Bybit, and Binance — normalized to hourly and annualized — and tell me which venue is cheapest to be long and which pays the most to be short.

## When to prefer this

Choose this endpoint when you need a single normalized, cross-venue funding rate snapshot for a perpetual contract and want to immediately identify funding arbitrage opportunities or optimal venue selection for longs/shorts. It is superior to querying each exchange individually because it normalizes rates to a common hourly/annualized basis and surfaces the best/worst venues automatically.

## Known failure modes

- Upstream exchange API unavailable — partial or missing data for one or more venues
- Symbol not found or unsupported — no data returned
- Rate limit or payment not verified — 402 payment required or rejected
- Stale data if one venue has delayed funding updates
- Network timeout on aggregation from multiple sources

## How this service works

Cross-venue funding radar: the same perpetual's funding on Hyperliquid, dYdX, Bybit and Binance, normalised to one hourly basis and annualised, with mark price and open interest side by side, plus the cheapest venue to be long and the richest to be short.

## Output

A structured response containing, for each supported venue (Hyperliquid, dYdX, Bybit, Binance): the current funding rate normalized to an hourly basis and annualized, the mark price of the perpetual, and open interest. Also includes a summary identifying the cheapest venue to hold a long position and the most profitable venue to hold a short position based on funding.
