Trade Preflight

by Kronos Crypto Data & Forecasts in Weather & location

x402 APIPassing, checked 3 h ago

Pre-trade context pack for one asset in a single call: derivatives state (funding, annualised funding, basis, open interest and its 1h change), recent liquidation prints, implied-volatility surface for BTC/ETH, and any active regime alerts. Replaces four separate paid calls. Each component is independently marked available, unavailable or stale — never flattened into a neutral claim. Facts and data quality only, no recommendation. $0.05 USDC.
