Rajju Dosha API

The Rajju Dosha API is a Vedic astrology endpoint that detects and analyses Rajju Dosha — a significant affliction in Hindu marriage compatibility that arises when the Janma Nakshatras (birth stars) of two individuals fall within the same Rajju (rope) category. Rajju Dosha is considered one of the more serious doshas in match-making, as it is believed to adversely affect the longevity and well-being of the couple, particularly the husband, depending on the type of Rajju involved.

What This API Does

This API accepts the complete birth details of two individuals — a male and a female — including their date, time, and geographic coordinates of birth. It derives the Janma Nakshatra of each individual and maps them to their respective Rajju category. The 27 Nakshatras are traditionally grouped into five Rajju types — Siro (head), Kantha (neck), Udara (stomach), Kati (waist), and Pada (feet) — each associated with a different type of harm if both partners share the same Rajju. The API determines whether a Rajju Dosha exists, identifies the Rajju type, and assesses the nature and severity of the affliction.

What Data It Returns

The API returns a structured Rajju Dosha report that includes:

• Nakshatra details for both individuals — the computed Janma Nakshatra for the male and female based on their birth data.

• Rajju classification — the Rajju category assigned to each individual's Nakshatra.

• Rajju Dosha status — whether a Rajju Dosha is present, i.e., whether both individuals share the same Rajju.

• Rajju type and associated impact — the specific Rajju type (Siro, Kantha, Udara, Kati, or Pada) and the traditional interpretation of the harm associated with that Rajju if the dosha is present.

• Cancellation or exception flags — any classical conditions under which the Rajju Dosha may be considered neutralised or reduced in severity.

Main Use Cases

• Pre-marriage horoscope matching — the primary use case; used by astrologers and matrimonial platforms to identify Rajju Dosha as part of a comprehensive compatibility check before recommending a match.

• Dosha severity assessment — used to distinguish between different levels of Rajju Dosha impact based on the specific Rajju type, enabling more nuanced match recommendations.

• Multi-dosha compatibility pipelines — integrated into automated astrology engines that evaluate multiple doshas (Mangal, Vedha, Rajju, Nadi, etc.) in sequence.

• Astrology SaaS and matrimonial platforms — powering Rajju Dosha detection within horoscope matching features for end users.

• Jyotish (Vedic astrology) software — providing programmatic Rajju Dosha computation for desktop or web-based astrology applications.

Key Functionality

• Accepts precise birth data (day, month, year, hour, minute, second, latitude, longitude, and timezone offset) for both individuals independently, enabling accurate Nakshatra derivation for each horoscope.

• Maps each individual's Nakshatra to one of the five classical Rajju categories and checks for a shared Rajju, which constitutes the dosha.

• Differentiates between Rajju types to convey the specific nature of the affliction, as each Rajju type carries a distinct traditional interpretation regarding its impact on the couple.

• Supports configurable Ayanamsha systems (e.g., Lahiri, Raman, KP) via the X-Ayanamsha header, ensuring compatibility with different schools of Vedic astrology.

• Supports multi-language responses via the Accept-Language header, making it suitable for localised and regional applications.

• Applies classical exception and cancellation rules to identify cases where the dosha is mitigated, providing a tradition-aligned and nuanced result.
