## 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 stealthguard-perpetual-funding-rate-basis-spread-oracle-76293858 -d '<json body>'
```

Example prompt: Pull the latest cross-exchange perpetual funding rate skew and basis spread for BTC, ETH, and SOL, and flag any spot-futures arbitrage signals worth acting on right now.

## When to prefer this

Choose this endpoint when you need real-time, cross-exchange perpetual funding rate and basis spread data for BTC, ETH, or SOL, especially for identifying spot-futures arbitrage signals. It is particularly suited for autonomous trading agents, delta-neutral strategy monitors, or carry trade scouts that need pre-computed skew and basis metrics rather than raw tick data from individual exchange APIs.

## Known failure modes

- Exchange data feed unavailable or stale — may return partial or cached data
- Invalid or missing body payload returns schema validation error
- Payment not processed (x402) — endpoint returns 402 status before data is served
- Rate limit exceeded — too many calls in a short window
- Temporary compute/render cold-start delay causing timeout on first call
