## 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 x402stock-predicted-perps-funding-rate-9a4caa13
```

Example prompt: Pull the predicted next-period funding rates for all coins across Hyperliquid, Binance, and Bybit so I can spot where the funding arbitrage spread is richest right now.

## When to prefer this

Use this endpoint when you need a unified, cross-venue view of predicted perpetual funding rates in a single call — especially for funding arbitrage strategies comparing CEX (Binance, Bybit) vs DEX (Hyperliquid, on-chain) rates. Prefer this over scraping individual exchange APIs when you want a normalized, pre-aggregated signal without managing multiple API keys.

## Known failure modes

- Network or upstream venue data unavailable — may return stale or null funding rate values for affected venues
- Payment failure — 402 response if USDC payment not supplied correctly
- Rate limiting or bad request — 4xx response if the call is malformed
- Venue temporarily offline — specific venue entries may have null funding_rate or null next_funding_time

## How this service works

Predicted next-period funding rate for each coin across venues — on-chain plus centralized perp venues (Hyperliquid, Binance, Bybit) — each with the funding interval and next funding time. A cross-exchange funding-arbitrage signal in one call: compare where a coin's funding is richest or cheapest. Free on-chain DEX data, no key. From x402stock, a market & economic data API (x402, USDC).

## Output

A JSON object containing an array of coins, each with a list of venues (Hyperliquid, Binance, Bybit, on-chain DEX) showing the predicted funding rate, funding interval in hours, and next funding timestamp. Also includes a top-level as_of timestamp, source identifier, and total coin count.
