get_card_for_birthdate
One birth date in → the full cosmic identity out: birth card, ruling planet, card class, plus layered systems for that date (tarot, sidereal, moon phase, season, retrogrades, and more).
Ask:
Get the card for birthdate 1985-03-15.geometry.app shows a teaching excerpt only. This page is a public docs sample (values from a live call; season anchors verified). Full payload / raw JSON: call with
birth_date only — the live response is the complete object (no verbosity flag). If a chat UI truncates, ask the agent to paste the raw tool result; that constrains the model, not this tool. Sample below is teaching shape; nested fields and arrays can be longer on the wire.
Example response
retrogrades_active is trimmed for display — the live array covers major planets, asteroids, TNPs, and points. Full wire payloads carry ~30 systems on one date.
Out of published range
Dates outside 1900–2100 return a soft envelope (temporal_context other than "full"), not a crash. Birth-card identity remains month/day based.
