## 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 meryol-agenticmarket-x402-hf-space-75358459
```

Example prompt: What are the current perpetual funding rates for ETH across Hyperliquid, dYdX, and Aevo — give me the 8h rate, annualized APR, open interest, and which venue has the best carry right now?

## When to prefer this

Use this endpoint when you need a real-time, multi-venue comparison of perpetual funding rates (not just a single exchange) for delta-neutral carry analysis, pre-trade funding assessment, or cross-venue arbitrage. Prefer over single-exchange APIs when the median or spread across Hyperliquid, dYdX, and Aevo is required.

## Known failure modes

- Unknown or unsupported ticker symbol returns 404 or empty venues array
- Rate limiting or payment failure (402) if x402 payment not properly submitted
- One or more venues may be unavailable, resulting in partial data with fewer venue entries
- Network timeout if upstream exchange APIs are slow
- Malformed market parameter (e.g. lowercase or invalid string) may return error

## 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

A JSON object with a 'venues' array containing per-exchange entries (exchange name, 8h funding rate, annualized APR, open interest in USD, mark price) and a 'median_apr' field summarizing the cross-venue median annualized funding rate.
