Not checked

Deterministic calendrical, astronomical, and divination computation nodes for AI agents. Each endpoint performs exact calculations that LLMs cannot reliably reproduce—solar-term boundaries via apparent solar longitude (Meeus), sexagenary cycle pillars, full natal charts (planet longitudes, ASC/MC, houses, aspects), and Zi Wei Dou Shu charts—each with cited accuracy bounds in a meta field. Verified against primary sources (NAOJ, JPL, Meeus). Pay-per-call via x402 (USDC on Base, CDP facilitator).
