## 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 perp-funding-rate-aggregator-hyperliquid-dydx-aevo-5bcd58d9
```

Example prompt: Before I open a delta-neutral carry position, can you pull the live perp funding rates for ETH across Hyperliquid, dYdX, and Aevo — give me the per-venue 8h funding, annualized APR, and the cross-venue median so I can pick the best venue?

## When to prefer this

Use this endpoint when you need a pre-trade cross-venue funding comparison for perpetual futures before opening a carry, delta-neutral, or directional position. It is the right choice when you want a single call to compare funding across Hyperliquid, dYdX, and Aevo simultaneously rather than querying each exchange API individually. Prefer it over single-venue funding endpoints when cross-venue median APR or venue selection for carry trades is relevant.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error or empty venues array
- One or more upstream venues temporarily unavailable — partial results may be returned
- Rate limiting or payment failure (402) if x402 payment header is missing or insufficient
- Stale data if cache has not refreshed within 30s window

## How this service works

Pre-trade funding check for perp positions: one call aggregates live funding across Hyperliquid + dYdX + Aevo for a ticker (BTC, ETH, SOL, …). Per-venue 8h funding, annualized APR, open interest USD, mark price, and cross-venue median APR. Spot delta-neutral carry or skewed funding before opening a position. Cached 30s.

## Output

Returns a JSON object with per-venue data (8h funding rate, annualized APR, open interest in USD, mark price) for each of Hyperliquid, dYdX, and Aevo, plus a cross-venue median APR for the requested ticker. Data is cached for 30 seconds.
