post
post_biorhythm_compatibility
Calculate biorhythm compatibility between two people by overlaying their cycle profiles on a target date. Returns per-cycle alignment scores (0-100) for physical, emotional, and intellectual cycles, an overall compatibility score, relationship rating, strengths, challenges, practical advice, and a daily sync snapshot showing the absolute difference in each primary cycle. Perfect for dating apps, relationship platforms, team-building tools, and couples coaching applications.
post_biorhythm_critical_days
Find all critical days (zero crossings) within a date range up to 180 days. Returns each critical day with cycle name, period, direction (ascending or descending), severity (single, double, or triple), and advisory text. Highlights rare double critical days where two primary cycles cross zero simultaneously and extremely rare triple critical days where all three primary cycles cross zero on the same date. Ideal for calendar integrations, push notification systems, alert engines, and wellness scheduling tools.
post_biorhythm_daily
Get a daily biorhythm reading with seeded randomness for consistent "biorhythm of the day" features. Same seed and same date always produce the same reading, perfect for daily push notifications, morning briefings, and wellness app check-ins. Returns energy rating, overall phase, a spotlight on one featured cycle, quick-read values for all three primary cycles, a daily message, and actionable advice. The spotlight cycle is deterministically selected by the seed, creating variety across users while maintaining consistency for each individual.
post_biorhythm_forecast
Generate a biorhythm forecast for a date range up to 90 days. Returns daily cycle values for physical, emotional, intellectual, and intuitive cycles, daily energy ratings, critical day identification, and a summary with best day, worst day, average energy, and period-level guidance. Ideal for wellness apps, productivity planners, scheduling tools, and calendar integrations that need forward-looking biorhythm data.
post_biorhythm_phases
Get current phase information for all 10 biorhythm cycles without the full interpretation payload. Returns value, phase name, phase label, day position within cycle, cycle period, days until next critical crossing, and short-term trend for each cycle. Includes a compact summary string. Designed as a lightweight endpoint for dashboards, widgets, status bars, and quick-check interfaces that need biorhythm phase data without editorial text.
post_biorhythm_reading
Calculate a complete biorhythm reading for a given birth date and target date. Returns all 10 cycle values (physical, emotional, intellectual, intuitive, aesthetic, awareness, spiritual, passion, mastery, wisdom), phase detection with 8 distinct states, energy rating (1-10), overall phase assessment, editorial-grade interpretation, actionable advice, and critical day alerts. Perfect for wellness apps, dating platforms, productivity tools, and AI chatbot integrations that need structured biorhythm data.
