Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 funding-rate-open-interest-by-venue-single-coin-ec751611 -d '<json body>'
```

Example prompt: Show me the funding rate and open interest for ETH broken down by Binance, Bybit, and OKX — I want to see if any single venue is way out of line with the others, which could signal a localized squeeze setup.

## When to prefer this

Choose this endpoint when you need venue-level granularity for a single coin — specifically when you suspect or want to detect localized positioning divergence across Binance, Bybit, and OKX. If you need multi-coin coverage in one call, use the sibling batch endpoint instead. This endpoint is ideal for squeeze-setup detection, pre-trade sentiment checks on a specific asset, and real-time cross-venue spread monitoring.

## Known failure modes

- Unsupported coin symbol returns an error or empty rows
- Venue API downtime may cause missing rows for that exchange
- Stale funding data if venue rate hasn't refreshed in the current 8-hour window
- Malformed coin ticker (e.g. including -USDT suffix) may cause lookup failure

## How this service works

Funding rate and open interest for one coin, broken down venue by venue across Binance, Bybit, OKX and Hyperliquid, using each venue's largest-open-interest perpetual. Use it when venue divergence matters: one venue far more positive or negative than the rest is localised positioning, not market consensus — the setup that precedes a squeeze on that venue alone. Returns per-venue rows plus average funding, total open interest and the spread.

## Output

A set of per-venue rows (Binance, Bybit, OKX) each containing the funding rate and open interest for the largest-OI perpetual on that venue for the requested coin, plus a summary row with average funding rate, total open interest across all venues, and the maximum spread between venues.
