## 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 crypto-perp-funding-rates-48787283 -d '<json body>'
```

Example prompt: Show me the top 10 crypto perp markets ranked by absolute funding rate right now, and include BTC, ETH, and SOL specifically — I want to see both the hourly and annualized rates.

## When to prefer this

Use this endpoint when you need live perpetual futures funding rate data across on-chain DEX markets, especially when you want to rank or filter markets by funding intensity. Prefer this over spot price or staking endpoints when your use case is derivatives-specific — identifying funding arbitrage, gauging market sentiment via funding sign, or screening for extreme funding events across a broad set of symbols.

## Known failure modes

- Unknown coin symbol returns empty result or error
- Limit exceeding 250 returns validation error
- Network or upstream DEX data unavailability returns 5xx
- Payment not attached or insufficient returns 402 Payment Required
- Malformed coins array (items too long or too many) returns 400

## How this service works

Live perpetual-futures funding rates per market — each market's funding rate as hourly, the standard 8-hour figure and annualized %, alongside mark price and open interest. Ranked by the most extreme (|annualized|) funding by default; pass `coins` to get the funding rate for a specific market (e.g. ["BTC","ETH"]). Real-time crypto perp funding rate feed. Data source: Hyperliquid (dYdX fallback).

## Output

Returns a ranked list of perpetual futures markets with per-market funding data including coin symbol, hourly funding rate, annualized funding rate, and absolute funding magnitude used for ranking. Results are sorted by highest absolute annualized funding by default, covering up to 250 markets or filtered to specified symbols.
