How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object with ETH derivatives analytics including: open interest (regime label like 'accumulation', current USD value, 24h delta percent), funding rate (current annualized percent, 30-day z-score, 7-day momentum, regime label like 'elevated_long_bias'), basis data (trend, current bps, 90d percentile), GEX value, symbol, and a metadata disclaimer.
Example use cases
ETH risk monitoring for portfolio
“Check the current ETH derivatives signals for me — is open interest expanding or contracting, and is the funding rate in dangerous territory based on the z-score? I want to know if I should reduce my ETH exposure right now.”
Detect ETH market regime shift
“Has the ETH market shifted regimes recently? Pull the latest open interest regime label and funding rate momentum — I'm trying to figure out if we're still in accumulation or if distribution has started.”
Automated trading signal pipeline check
“Before I run my ETH perpetual futures strategy today, give me a full read on the derivatives layer — what's the basis trend, where does funding sit relative to its 30-day z-score, and what's the 24-hour open interest delta looking like?”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/derivatives-analytics/ETHWhen to prefer
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.
Side effects
- 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
