Transit Context Endpoint #

POST /api/v5/context/transit #

View Complete Example

Generates an AI-optimized XML-structured interpretation of a transit chart. This endpoint analyzes how the current (or future) positions of the planets affect a person’s natal chart. It is essential for forecasting, understanding current life themes, and predictive astrology.

Request Body #

  • first_subject (object, required): The natal subject (the person receiving the transits). See Subject Object Reference.
    {
        "name": "Natal Subject",

    }
    
  • transit_subject (object, required): The transit moment. Uses a simplified subject model — does not include zodiac_type, sidereal_mode, perspective_type, or houses_system_identifier (these are inherited from first_subject). The name field defaults to "Transit".
