Planets Advanced

Endpoint POST https://starsapi.com/api/v3/western/natal/planets-advanced

Overview

Returns everything from natal/planets plus an advanced block per planet containing essential dignities (domicile, detriment, exaltation, fall, triplicity, term, face), solar proximity (cazimi, combust, under the sunbeams), sect analysis, stationary detection, oriental/occidental orientation, and speed classification. Also returns chart-level data: chart_sect (diurnal/nocturnal) and mutual_receptions between classical planets.

Use this endpoint when building detailed chart analysis features, dignity score tables, or traditional astrology tools. For basic positions without the advanced overlay, use natal/planets instead.

Authentication

Method	Example
Header (recommended)	`X-Api-Key: am_live_xxxxxxxxxxxx`
Bearer	`Authorization: Bearer am_live_xxxxxxxxxxxx`
Query	`?api_key=am_live_xxxxxxxxxxxx`

Request body

Field	Type	Required	Description
`year`	integer	Yes	Birth year (1800–2400).
`month`	integer	Yes	Birth month (1–12).
`day`	integer	Yes	Birth day.
`hour`	integer	Yes	Birth hour (0–23).
`minute`	integer	Yes	Birth minute (0–59).
`second`	integer	No	Birth second. Default `0`.
`latitude`	number	Yes	Decimal degrees (−90 to 90).
`longitude`	number	Yes	Decimal degrees (−180 to 180).
`timezone`	string	Yes	IANA timezone.
`house_system`	string	No	Default `placidus`. See house systems.
`node_type`	string	No	`true`, `mean`, or `both`. Default `true`.

Response shape

`data.chart_sect`

"diurnal" (Sun above horizon) or "nocturnal" (Sun below). Determines triplicity rulers and sect-based dignity bonuses.

`data.planets.{name}.advanced`

Each planet has an advanced object with the following:

Essential dignities

The advanced.dignity block follows the Ptolemaic essential dignity scoring system:

Field	Type	Description
`status`	string	Primary dignity: `domicile`, `exalted`, `detriment`, `fall`, `peregrine`, or `neutral`.
`domicile`	boolean	Planet is in its own sign (+5 points).
`detriment`	boolean	Planet is in the sign opposite its domicile (−5 points).
`exalted`	boolean	Planet is in its exaltation sign (+4 points).
`fall`	boolean	Planet is in the sign opposite its exaltation (−4 points).
`triplicity`	string\|false	`"day"`, `"night"`, `"participating"`, or `false`. Dorothean triplicity system (+3 day/night, +1 participating).
`term_ruler`	string	Egyptian/Ptolemaic term ruler at this degree.
`in_own_term`	boolean	Planet is the term ruler at its own position (+2 points).
`face_ruler`	string	Chaldean decanate ruler (10° divisions).
`in_own_face`	boolean	Planet is the face ruler at its position (+1 point).
`peregrine`	boolean	True if the planet has no essential dignity at all.
`score`	integer	Total dignity score (can be negative).

Solar proximity

The advanced.solar_proximity field is null when the planet is far from the Sun. When close:

Status	Distance from Sun	Meaning
`cazimi`	< 0°17′	In the heart of the Sun — extremely powerful.
`combust`	< 8°	Burned by the Sun — weakened, hidden.
`under_sunbeams`	< 17°	Under the Sun’s beams — mildly weakened.

Returns { "status": "combust", "distance": 3.4521 } or null.

Sect

The advanced.sect block:

Field	Description
`planet_sect`	`"diurnal"` (Sun, Jupiter, Saturn) or `"nocturnal"` (Moon, Venus, Mars). Mercury adapts to chart sect.
`in_sect`	True if the planet’s natural sect matches the chart sect. In-sect planets perform better.

Other advanced fields

Field	Type	Description
`is_stationary`	boolean	True when the planet’s speed is near zero (about to change direction). Uses planet-specific thresholds.
`orientation`	string\|null	`"oriental"` or `"occidental"` relative to the Sun. Null for Sun and Moon.
`speed_classification`	string	`retrograde`, `very_slow`, `slow`, `average`, `fast`, or `very_fast` relative to the planet’s mean daily motion.

`data.mutual_receptions`

Array of mutual reception pairs among classical planets (Sun through Saturn). Two types detected:

Type	Meaning
`domicile`	Each planet is in the other’s ruling sign (e.g. Mars in Cancer + Moon in Aries).
`exaltation`	Each planet is in the other’s exaltation sign (e.g. Sun in Taurus + Moon in Aries).

Errors

HTTP	Code	Cause
400	`MISSING_FIELD`	A required field is absent.
400	`INVALID_DATE`	Invalid calendar date or year outside range.
400	`INVALID_TIME`	Hour/minute/second outside valid range.
400	`INVALID_TIMEZONE`	Not a valid IANA identifier.
400	`INVALID_COORDINATE`	Latitude or longitude out of range.
400	`INVALID_PARAM`	Invalid `house_system`.
500	`EPHEMERIS_ERROR`	Swiss Ephemeris computation failed.
