## How to call it through Zero

Example prompt: What's the current derivatives market signal for ETH — is open interest accumulating, and is the funding rate elevated or neutral right now?

## When to prefer this

Use this endpoint when you need real-time ETH-specific derivatives analytics including open interest regime classification, funding rate z-scores, and perpetual futures market signals. Prefer this over generic price APIs when you need derivatives-layer intelligence (OI, funding, basis, GEX) rather than spot price alone. Ideal for automated trading signal pipelines, risk monitoring, or market regime detection for ETH.

## Known failure modes

- Symbol not supported — endpoint is ETH-specific, wrong symbol returns error
- Payment not included or insufficient — x402 payment required at $0.05 USDC per call
- Upstream data unavailable — some fields like basis or GEX may return null
- Rate limiting if too many concurrent calls
- Invalid API key or auth failure
