## 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-extreme-funding-rates-ebd0c803
```

Example prompt: Show me the top 5 highest and lowest annualized funding rates across Binance and Hyperliquid perps right now, only for contracts with at least $10M open interest.

## When to prefer this

Use this endpoint when you need a cross-venue leaderboard of extreme funding rates — both highest and lowest — across Binance USDT-margined perps and Hyperliquid simultaneously, with open interest filtering to exclude illiquid markets. Prefer this over single-coin endpoints when you want to discover which symbols have the most anomalous funding conditions without specifying a coin upfront.

## Known failure modes

- No markets meet the minOiUsd threshold — returns empty highest/lowest arrays
- limit parameter out of range (must be 1–50) — returns validation error
- Upstream exchange data unavailable — may return partial results or stale data
- Invalid query parameter types — non-numeric strings for minOiUsd or limit cause errors

## How this service works

Highest and lowest annualized funding rates across all Binance USDT-margined perpetuals and Hyperliquid perps, with open interest in USD and a minimum open interest filter (default $5M).

## Output

A JSON object containing two ranked lists — 'highest' and 'lowest' funding rate perpetuals — each with venue name, coin symbol, raw funding rate, open interest in USD, annualized funding rate percentage, and funding interval in hours. Also returns the applied minimum OI filter and the total number of eligible markets scanned.
