How this service works
Precision Moment: JPL DE440-backed astrology for one exact UTC instant and Earth location—raw apparent positions, houses, Ascendant/MC, nodes, lots, sect, dignities, expanded aspects, and cross-engine measurement evidence.
Output
Returns a comprehensive astrological dataset for the requested moment including: apparent tropical positions for 10+ celestial bodies, house cusps for the selected house system, Ascendant and Midheaven, mean and true lunar nodes, Arabic lots (e.g. Part of Fortune), sect determination, essential and accidental dignities, a full expanded aspect table, and cross-engine measurement evidence for validation — all computed using the JPL DE440 ephemeris.
Example use cases
Natal chart for birth certificate time
“Calculate a complete natal chart for someone born on March 3, 1985 at 07:45 UTC in London (latitude 51.5074, longitude -0.1278) — I need the Ascendant, Midheaven, all house cusps, planetary positions, dignities, and aspects using the Placidus system.”
Electional astrology for business launch
“I'm planning to launch my business and want to find the astrological conditions for October 10, 2025 at 09:00 UTC in Tokyo (latitude 35.6762, longitude 139.6503) — give me the full precision chart including sect, dignities, lots, and aspects.”
Historical event astrological analysis
“Pull the full JPL DE440 precision moment chart for the Apollo 11 moon landing — July 20, 1969 at 20:17 UTC at Cape Canaveral (latitude 28.5721, longitude -80.6480) — I need all planetary positions, nodes, lots, house cusps, and aspects.”
Technical details
Endpoint
GEThttps://ephemeris.561.group/v1/ephemeris/precision-moment/:dateWhen to prefer
Choose this endpoint when you need the most comprehensive astrological chart data for a single moment — including houses, Ascendant/MC, nodes, lots, dignities, sect, and full aspect data — backed by the authoritative JPL DE440 ephemeris. Prefer this over the sibling 'Moment Essentials' endpoint when you need more than just the 10 basic body positions and require cross-engine measurement evidence or the full suite of derived astrological points.
Side effects
- Invalid or malformed UTC date string returns a 400 error
- Missing or out-of-range latitude/longitude returns a validation error
- Dates outside JPL DE440 coverage range may return an error or degraded results
- Unrecognized house system parameter returns a 400 error
- Network timeout if ephemeris computation takes longer than expected
