## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-8bb9a88f
```

Example prompt: What's the current derivatives outlook for BTC — specifically the 30-day funding rate z-score, carry regime, and open interest trend across Binance, Bybit, and OKX?

## When to prefer this

Use this endpoint when you need derivatives-specific market intelligence — funding rate extremes, carry regimes, or OI momentum — for any of the 34 supported coins. Prefer over generic price endpoints when the user is asking about perpetuals sentiment, funding conditions, or whether the market is positioned long or short. The 730-day history and multi-exchange OI aggregation make it more robust than single-exchange funding rate queries.

## Known failure modes

- Unsupported coin ticker returns 400 or empty — only 34 specific coins are supported
- Network timeout or 5xx if upstream exchange data is unavailable
- Payment failure (402) if x402 USDC payment not included or malformed
- Invalid path parameter format (e.g. lowercase ticker) may result in 404 or error

## How this service works

Derivatives market analytics: funding rate z-score (30d), 7d funding momentum, annualized carry with regime classification (elevated_long_bias/elevated_short_bias/positive_carry/negative_carry/neutral), open-interest total USD across Binance/Bybit/OKX, 24h OI delta with accumulation/distribution/short_buildup regime. Built on 730d funding history + own OI pipeline. Informational research data — not investment advice.

## Output

Returns a JSON object with funding analytics (z-score, 7d momentum, annualized carry, regime label like elevated_long_bias/positive_carry/neutral), open interest total in USD across Binance/Bybit/OKX, 24h OI delta, and an OI regime classification (accumulation/distribution/short_buildup), plus metadata. Based on 730-day funding history and a proprietary OI pipeline.
