## 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 funding-rate-arbitrage-spread-calculator-2e9a53e6
```

Example prompt: Show me all the funding rate arbitrage spreads for BTC across Binance, Bybit, and Hyperliquid — sorted by annualized bps divergence — and tell me which side to short and which to long for each pair.

## When to prefer this

Use this endpoint when you need a comprehensive pairwise comparison of funding rates across Binance, Bybit, and Hyperliquid — not just the single best spread — including directional trade guidance. Prefer this over raw /funding-rates when you want pre-computed arbitrage spreads sorted by opportunity size.

## Known failure modes

- Unknown or unsupported symbol returns empty results or 404
- Payment not provided or invalid returns 402 error
- Rate limiting or cache miss may cause slight delay
- Network timeout to upstream exchange data may return stale or error response

## How this service works

Live web search (keyless — no Exa/API account needed, we pay upstream) and real-time cross-exchange crypto funding-rate data + arbitrage signals, paid per call in USDC on Base via x402. For AI agents that need live data without holding any API keys.

## Output

A JSON array of all pairwise funding-rate spreads for the requested symbol (or top 20 across all symbols if no symbol is specified), each entry including the two exchange names, annualized bps divergence, and the direction (short on high-funding venue, long on low-funding venue). Data is cached for 60 seconds.
