## 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 booaip-crypto-derivatives-data-api-6d0fc807
```

Example prompt: What's the current derivatives market sentiment for BTC — is it mild long or short, and what's the average funding APR and spread across exchanges right now?

## When to prefer this

Use this endpoint when an AI agent needs real-time crypto derivatives market intelligence — specifically funding rate sentiment, APR, and cross-exchange spread — for a given token symbol. Prefer this over generic price APIs when the task involves perpetual futures positioning, funding arbitrage analysis, or market sentiment from the derivatives market.

## Known failure modes

- Unsupported or invalid symbol returns an error or empty response
- Network timeout from upstream data provider
- Symbol not listed on any tracked derivatives exchange
- Payment not completed via x402 results in 402 response blocking data
- Stale data if upstream aggregator has a delay
