Search a bounded interval for planetary ingresses, stations and exact major aspects

Returns only physical apparent-geocentric longitude events: selected-zodiac sign-boundary crossings, tropical-longitude motion reversals and exact major-aspect longitude crossings. No aspect orbs, tangential contacts, houses, interpretations, eclipse claims, arbitrary targets, user kernels or search tuning. UTC dates 1800–2200; whole-second start-inclusive/end-exclusive intervals span at most 31 days. One-second timestamps and a 0.05-second numerical root tolerance are not physical accuracy guarantees. Independent Swiss Ephemeris/Moshier fixtures cover representative 2026 ingresses, stations and an exact aspect within 30 seconds; broader epoch acceptance remains separate. Each admitted request reserves one standard monthly quota unit before route validation or engine work, including failures and timeouts; failed or timed-out admitted attempts are not refunded. All plans; do not automatically retry. Source availability does not establish deployment. Historical mode uses an explicit BCE/CE date object and UT1 conventions. Its response is the versioned historical envelope, not the modern UTC envelope. Read result for calculation fields and metadata for limits and uncertainty.
