Prewritten readings for one planet passing over another planet's birth position — transiting Saturn over the natal Moon, transiting Jupiter over the natal Sun, and so on. This is the pairwise transit table most transit reports are built from.
It is a pure lookup with no chart calculation behind it: supply the transiting planet as `planet` and the birth-chart planet as `natal_planet` and you get the text back. Work out which contacts are actually live from a transit calculation such as `/api/astro/transit/` first, then call this for the wording.
Both arguments accept the nine bodies, although the transiting side omits Venus. Order matters: Saturn over the natal Sun is a different entry from the Sun over natal Saturn.

array

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.

string
required

Exact lower-case match. All 9 are present under every transiting planet (verified by AST-parsing the mapping). An unknown value returns "Invalid key: <x>" with HTTP 200.
planet
string
required

NOTE: 'venus' is MISSING as a transiting planet - the mapping has only these 8 top-level keys. An unknown value returns "Invalid key: <x>" with HTTP 200.

Ask for exactly the calculations you want by listing them in keys. An unknown key rejects the whole request, and you are charged 1 credit however many you ask for — so batch them.

Description
get_planet_transit_natal_planets
planet, natal_planet
The reading for `planet` transiting over the birth position of `natal_planet`. Returns a list of short phrases, usually two to four, each a separate statement about the contact. The pair is directional, so the transiting planet and the natal planet are not interchangeable.
