## 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 live-perpetual-funding-rates-api-d26e7073
```

Example prompt: What's the current funding rate for BTC across Hyperliquid, Bybit, and the other supported venues — give me the hourly rate and APR for each?

## When to prefer this

Use this endpoint when you need normalized, cross-venue perpetual funding rate data aggregated in a single call. It is preferable to querying individual exchange APIs separately because it normalizes all rates to hourly and APR formats, covers 5 venues simultaneously, and is already aggregated and cached. Choose this over the arbitrage scanner sibling when you want raw rate data rather than pre-computed spread opportunities.

## Known failure modes

- Unknown coin symbol returns empty rates array or error
- Invalid venue parameter ignored or returns error
- Cache may return data up to 60 seconds stale
- Payment failure (x402) if USDC balance insufficient — returns 402 Payment Required
- Venue API downtime may result in missing entries for that venue in the response

## How this service works

Live perp funding rates across 5 venues (Hyperliquid, Bybit, Pacifica, Extended, Lighter), normalized to hourly rate and APR %, with mark price and open interest. Query: coin (optional, e.g. BTC), venue (optional). Cached <=60s. $0.005 per call.

## Output

A JSON object with an 'asOf' UTC timestamp and a 'rates' array. Each element includes: coin symbol, venue name, hourly funding rate (decimal), APR percentage, and optionally mark price and open interest. Data is cached for up to 60 seconds.
