## 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 x402-defi-funding-rates-cross-venue-perpetual-signal-688014bd
```

Example prompt: What are the current annualized perpetual funding rates for ETH across OKX, Kraken Futures, and dYdX, and what's the cross-venue spread I could use for a funding arb?

## When to prefer this

Choose this endpoint when you need a single-call cross-venue funding rate comparison across OKX, Kraken Futures, and dYdX with the spread pre-computed as an arbitrage signal, rather than querying each exchange API separately and computing the spread yourself. Ideal for trading bots, research agents, and strategy pipelines that need clean JSON funding signals without exchange API credentials.

## Known failure modes

- Unsupported or unrecognized token symbol returns an error or empty result
- One or more upstream venue APIs (OKX, Kraken, dYdX) is unavailable causing partial or stale data
- Missing required symbol query parameter may return an error or default response
- Payment not processed (x402 protocol failure) results in 402 response and no data returned
- Rate limits or cold-start latency on Render hosting may cause timeouts
