Get the twelve Arudha padas - Arudha Lagna Calculator API

post_vedic_astrology_arudha

Read-only

Calculate the Arudha Lagna (AL) and all twelve Arudha padas of Jaimini astrology from birth details. An Arudha pada is the perceived or projected form of a bhava, so where the Lagna shows what a person is, the Arudha Lagna shows the image and status the world attaches to them. Returns each pada with the bhava lord and the count that produced it, the sign it lands in, its house from the Lagna, and a flag showing whether the classical exception moved it. Includes the Upapada (UL) read for marriage. Arudha Lagna calculator API, Jaimini pada, Upapada Lagna, Vedic astrology public image.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`date`	Yes	Birth date in YYYY-MM-DD format. Date determines planetary positions and nakshatra calculations for Vedic kundli (janam patri). Accurate birth date is essential for dashas, yoga calculations, and divisional charts (vargas).
`lang`	No	Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.	en
`time`	Yes	Birth time in 24-hour HH:MM:SS format. Time is CRITICAL for Lagna (Ascendant) calculation and house divisions. It changes every two hours roughly. Even minutes matter for accurate nakshatra pada and divisional chart (D9, D10) calculations. Without exact time, Lagna and house-based predictions will be incorrect.
`compact`	No	Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.
`ayanamsa`	No	Sidereal frame (ayanamsa) the chart is cast in. "lahiri" is Lahiri/Chitrapaksha, the traditional Vedic standard used by most software, and is the default. "raman" is the B.V. Raman ayanamsa from Hindu Predictive Astrology, about 1.45 degrees below Lahiri. "kp-newcomb" and "kp-old" are the two Krishnamurti Paddhati frames. "custom" takes your own value in degrees via ayanamsaValue, for reconciling exactly against a specific reference program. The frame rotates the whole zodiac, so a graha sitting within 1.45 degrees of a boundary can change rashi or nakshatra when you switch: pick the one your reference software uses and keep it.	lahiri
`latitude`	Yes	Birth location latitude in decimal degrees. Location determines local sidereal time for Lagna calculation and affects bhava (house) cusps. Example: Delhi 28.6139, Mumbai 19.0760, Kathmandu 27.7172.
`timezone`	No	Timezone: an IANA name (e.g. "America/New_York", "Europe/London", or `cities[0].timezone` from /location/search) or decimal hours from UTC (e.g. -5 for EST, 5.5 for IST). An IANA name is resolved to the offset in force at the given date and time. Defaults to 5.5.
`longitude`	Yes	Birth location longitude in decimal degrees. Affects local time calculations and ayanamsha adjustments. Example: Delhi 77.2090, Mumbai 72.8777, Kathmandu 85.3240.
`ayanamsaValue`	No	Custom ayanamsa value in degrees. When provided, overrides the computed ayanamsa from the selected type. Use for testing with specific ayanamsa values or matching a particular reference source.

TDQS

A3.9/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds meaningful behavioral context: it explains the astrological meaning of an Arudha pada, states that the classical exception (Parivrajika/exception rule) is reflected via a flag, and notes that the Upapada is included. It also clarifies the return shape (each pada with lord, count, sign, house, flag). This goes beyond the annotations without contradicting them.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single focused paragraph that front-loads the core function ('Calculate the Arudha Lagna and all twelve Arudha padas') before explaining the concept and output. The trailing keyword-like phrases ('Arudha Lagna calculator API, Jaimini pada, Upapada Lagna, Vedic astrology public image') are somewhat redundant and add little for an AI agent, but they don't bloat the description enough to drop below a 4.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has an output schema, so the description doesn't need to enumerate return fields in detail, but it does summarize them helpfully. With 9 parameters, 100% schema coverage, and read-only annotations, the description covers the conceptual 'why' and the key output highlights. It doesn't mention pagination or rate limits, but for a single-shot calculation API with an output schema, this is adequate. A 4 is appropriate; a 5 would require explicit alternative routing or edge-case guidance.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all 9 parameters thoroughly. The description adds no parameter-specific detail beyond what the schema provides, but it doesn't need to. The baseline of 3 applies because the schema carries the heavy lifting and the description correctly focuses on the output semantics rather than repeating parameter docs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Calculate'), a specific resource ('Arudha Lagna and all twelve Arudha padas'), and explains the astrological concept (perceived/projected form of a bhava). It also names the output components (bhava lord, count, sign, house, exception flag, Upapada), which distinguishes it from sibling tools like rashis or nakshatras that return different chart elements.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use it: when you need the Arudha Lagna, the twelve padas, or the Upapada for marriage-related readings. However, it does not explicitly state when NOT to use it or name alternative tools (e.g., use get_vedic_astrology_rashis for rashi positions, or post_vedic_astrology_birth_chart for the full chart). The context is clear but exclusions are absent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
