## 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 perps-genexxis-open-interest-76d15963
```

Example prompt: What's the current open interest for BTC perpetuals across Binance, Bybit, OKX, and Hyperliquid — in both contracts and USD — and which exchange has the biggest market share right now?

## When to prefer this

Use this endpoint when you need a unified, cross-exchange view of perpetual futures open interest for a specific coin, particularly when you want market share breakdown, USD-equivalent figures, 24h change metrics, and the Binance long/short ratio all in a single call. Prefer it over scraping individual exchange APIs when you want aggregated, normalized data without managing multiple integrations.

- Symbol not listed on one or more venues returns partial data for those venues
- Network or upstream exchange API outage may return stale or missing data
- Missing required 'symbol' query parameter returns a validation error
- Payment not included or insufficient results in 402 Payment Required
