# get_card_for_birthdate

> One birth date → full cosmic identity + temporal layers (Tool 2).

# 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).

|             |                                                          |
| ----------- | -------------------------------------------------------- |
| **Input**   | `birth_date` (YYYY-MM-DD)                                |
| **Range**   | `1900-01-01` … `2100-12-31` → `temporal_context: "full"` |
| **MCP URL** | `https://mcp.geometry.app/mcp`                           |

**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.

`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.
