How this service works
Deterministic apparent tropical ephemeris with signs, motion, lunar phase, aspects, provenance and audited error bounds.
Output
A structured JSON object containing: the requested UTC instant, reference frame (tropical), per-planet apparent geocentric ecliptic longitude/latitude/speed, zodiac sign placements, retrograde/direct motion flags, current lunar phase, list of active aspects between bodies, provenance metadata (data source and computation method), and audited numerical error bounds for accuracy verification.
Example use cases
Birth chart planetary snapshot
“I need the full tropical ephemeris for August 15, 1990 at 14:30 UTC — what signs are all the planets in, is anything retrograde, and what aspects are active at that moment?”
Astrological event timing check
“Can you tell me the lunar phase and any major planetary aspects on the exact moment of the 2026 summer solstice, June 21, 2026 at 00:00 UTC?”
Retrograde research verification
“Is Mercury retrograde on March 3, 2025 at 12:00 UTC? Give me the full planetary motion data and aspects so I can verify my ephemeris table.”

Endpoint
GEThttps://market.561.group/v1/ephemeris/moment/2026-07-21T00:00:00Z?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, audited ephemeris with explicit error bounds and provenance metadata for a single UTC moment — particularly valuable for applications requiring reproducibility, auditability, or verification of astrological computations. Prefer over general astronomy APIs when tropical zodiac framing, aspect lists, and lunar phase are all needed together in one call.
Side effects
- Invalid or malformed ISO-8601 date string returns a 400 error
- Dates outside supported historical or future range may return an error or reduced accuracy
- Missing path parameter 'date' causes a validation error
- Payment of 0.04 USDC required per call; insufficient payment returns 402
- Network timeouts or server errors return 5xx responses
