Astro Agents Time Resolve
x402
Astro Agents Time Resolve is a paid API for AI agents from astro-agent.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).
Resolves a civil or ambiguous date/time and location into precise UTC, Julian Day, Delta-T, and true solar time using NASA/JPL DE440 ephemeris

How this service works
Birth time resolver: Local birth time + place -> exact UT, historical UTC offset, Delta T, Local Mean Time, true solar time.
Output
Returns a JSON object containing: resolved UTC datetime, timezone name and UTC offset, Julian Day UT (high-precision float), Delta-T in seconds, true solar time, plus engine metadata (ephemeris version, llm_used=false, deterministic=true) and a SHA-256 hash of the result for reproducibility verification.
Example use cases
Birth chart time normalization
“I need to calculate a natal chart for someone born on March 21, 1985 at 3:45 AM local time in Los Angeles (latitude 34.0522, longitude -118.2437, timezone America/Los_Angeles) — can you resolve that civil time to UTC and get me the Julian Day and Delta-T?”
Historical event time resolution
“Resolve the datetime of the moon landing — July 20, 1969 at 8:17 PM UTC at latitude 0.6741 north, longitude 23.4733 east — and give me the Julian Day UT and true solar time for that moment.”
Vedic astrology lagna calculation prep
“For a Vedic birth chart, I need the Julian Day and true solar time for someone born on January 12, 2001 at 6:00 AM IST in Mumbai (latitude 19.076, longitude 72.8777, timezone Asia/Kolkata) — please resolve the civil time to UTC with Delta-T.”
Technical details
Endpoint
POSThttps://astro-agent.dev/v1/time/resolve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need astronomically precise, reproducible time resolution for astrological or astronomical calculations — especially when you require Julian Day UT, Delta-T correction, or true solar time. It is ideal for natal chart preparation, historical event timing, or any workflow requiring a verifiable SHA-256 hash of the time result. Prefer it over generic timezone converters when NASA/JPL DE440 ephemeris accuracy and deterministic outputs are required.
Side effects
- Missing required body fields (date, time, or datetime) returns a validation error
- Latitude or longitude out of range (-90 to 90 / -180 to 180) returns a schema validation error
- Invalid or unrecognized timezone string causes a resolution failure
- Date outside ephemeris range (1800-01-01 to 2200-01-01) may return an out-of-range error
- Ambiguous DST transition times handled by ambiguous_time enum (earlier/later); wrong selection may produce unexpected UTC offset
- Payment failure via x402 protocol results in 402 status and no computation
