Provides deterministic computation of magnetic declination and sky positions (sun, moon, planets) for any location and time, enabling agents to get accurate ephemeris and geomagnetic data without hallucination.
Provides astronomical data including ISS tracking, moon phases, NASA APOD, near-Earth objects, exoplanets, space weather, and upcoming celestial events without requiring an API key.
Enables timezone conversion, astronomical calculations, and date utilities through natural language, supporting sunrise/sunset, moon phases, business days, and more.
Provides astronomical calculations using the Swiss Ephemeris library, including planetary positions, houses, chart points, and asteroids for any date and location.
