-d '{"date_time":"2025-01-01T00:00:00+00:00","tz":0,"when":"after","planet":"mars","degr":135}'When a planet reaches a given degree, within a date window. Choose the body with `planet` and the degree with `degr`. Leave `datetime_start` and `datetime_end` out and the window runs from the given moment to a year later, so a first call works without inventing one.
| Field | Type | Required | Notes |
|---|---|---|---|
| date_time | string (date-time) | required | The moment to calculate for, ISO 8601. ALWAYS include an offset or a trailing Z - a value with no zone is read as Asia/Kolkata (UTC+05:30), not UTC, and can return the previous day's result with a 200. '2026-09-01T06:00:00Z' and '2026-09-01 06:00:00' are different instants and give different answers. |

| celestial1 | string | optional | sunmoonmercuryvenusmarsjupitersaturnuranusneptuneplutomean_nodetrue_node |
| celestial2 | string | optional | sunmoonmercuryvenusmarsjupitersaturnuranusneptuneplutomean_nodetrue_node |
| datetime_end | string (date-time) | optional | |
| datetime_start | string (date-time) | optional | |
| degr | number (double) | optional | min 0 · max 360 |
| keys | array | optional | Which calculations to return, as a list of names. See the key table for this endpoint; an unrecognised name rejects the whole request. One call costs one credit however many keys you ask for, so request everything you need at once rather than making several calls. |
| latitude | number (double) | optional | Latitude of the place, in decimal degrees. Positive is north, negative is south. Example: 26.9124 for Jaipur, 40.7128 for New York. Minutes and seconds are not accepted - convert first. min -90 · max 90 |
| longitude | number (double) | optional | Longitude of the place, in decimal degrees. Positive is east, negative is west. Example: 75.7873 for Jaipur, -74.0060 for New York. Note the sign: a missing minus puts New York in China. min -180 · max 180 |
| planet | string | optional | sunmoonmercuryvenusmarsjupitersaturnuranusneptuneplutomean_nodetrue_node |
| timezone_as_float | number (double) | optional | UTC offset of the place, in hours, as a decimal. Example: 5.5 for India (UTC+05:30), -5 for New York in winter, 5.75 for Nepal. This is NOT validated against date_time - if the two disagree you get a successful response for the wrong moment, so derive both from the same source. Use the offset in force on that date, not today's: a summer birth in a country with daylight saving needs the summer offset. min -12 · max 14 |
| tz | number (double) | optional | UTC offset the returned times are expressed in. min -12 · max 14 |
| when | string | optional | Forward only; see the module docstring on `before`. after |
| x2cross | number (double) | optional | Ecliptic longitude to cross, 0-360 from 0 Aries. min 0 · max 360 |
