GET /eclipse-check$0.02Can a solar or lunar eclipse happen at the new and full moon nearest a date? Type, ecliptic-latitude margin and syzygy times.
GET /equation-of-time$0.02Equation of time in minutes for a date (sundial minus clock), and the clock time of solar noon at a longitude.
GET /moon-position$0.02Moon azimuth and altitude for a lat/lon and UTC moment, plus distance in km, illuminated fraction, phase and parallax.
GET /planet-positions$0.02Geocentric ecliptic longitude/latitude, RA/Dec, distance and Sun elongation for Mercury to Neptune; arcminute accuracy.
GET /planet-visibility$0.03Which planets are above the horizon an hour after sunset for a lat/lon and date: altitude, azimuth, elongation, set time.
GET /rise-set-moon$0.02Moonrise, moonset and transit for a lat/lon and local date, with azimuths and illumination; handles days with no rise or set.
GET /rise-set-sun$0.02Sunrise, sunset, solar noon, three twilights, golden and blue hour for a lat/lon and date; handles polar day and night.
GET /sun-position$0.02Sun azimuth and altitude for a lat/lon and UTC moment, with refraction-corrected altitude, RA/Dec, distance and twilight phase.
