Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/history/funding/SOLWhen to prefer
Use this endpoint when you need historical funding rate data specifically for SOL perpetual futures, including statistical summaries and time-series breakdowns. Prefer it over generic market data APIs when you need annualized funding rate calculations, mean statistics, or want to assess carry cost and market sentiment for SOL perps over a configurable lookback window.
Side effects
- Symbol not supported or incorrectly specified — returns error or empty dataset
- Insufficient funding rate history available for the requested period
- Upstream exchange data unavailable — may return stale or partial data
- Payment not processed (x402 protocol failure) — request rejected before data is returned
- Rate limit exceeded — too many calls in a short window
