Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
dateYesBirth 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).
langNoResponse 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
timeYesBirth 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.
focusNoWhich signification vocabulary the houseThemes map returns. "general" gives the classical bhava significations (self, wealth, siblings, home, and so on). "finance" gives the money reading of the same twelve bhavas, so house 2 returns income and savings, 5 speculation and risk appetite, 8 sudden money and leverage, 11 gains and profits, and 12 expenses and capital outflow. Use "finance" for wealth, income, business and market timing questions in Krishnamurti Paddhati, where the significator house groups 2, 6, 10, 11 for earned income and 5, 8, 11 for speculation are read against a running dasha. Defaults to "general".general
compactNoSet 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.
ayanamsaNoSidereal 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
latitudeYesBirth 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.
timezoneNoTimezone: 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.
longitudeYesBirth location longitude in decimal degrees. Affects local time calculations and ayanamsha adjustments. Example: Delhi 77.2090, Mumbai 72.8777, Kathmandu 85.3240.
avasthaInfoNoSet true to include a localized meaning and one-sentence classical interpretation beside each graha avastha state, under avasthaInfo on that graha in meta. Defaults to false, so an existing integration is byte-identical until it opts in. Saves a second call to GET /avasthas and the client-side join that would otherwise be needed to turn Yuva or Swapna into readable text.
ayanamsaValueNoCustom 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.
modernPlanetsNoSet true to also return Uranus, Neptune and Pluto, under the Sanskrit names Arun, Varun and Yam that Indian software prints for them. They arrive in a separate modernPlanets array, NOT inside meta, because classical Jyotish is defined over nine grahas: the moderns rule no sign, so they have no dignity, avastha, combustion or aspect strength and it would be fabrication to report one. Each carries longitude, rashi, degree in sign, nakshatra with pada and lord, and retrograde status. Defaults to false, so an existing integration is byte-identical until it opts in.

TDQS

B3.3/5.0
Behavior3/5

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 and the bar for additional disclosure is lower. The description adds that results are 'grouped by zodiac signs (rashis) with nakshatra details and pada,' which is useful output-shape context, but 'accurate' and 'complete' are quality claims, not behavior, and nothing is said about pagination, size, or response structure beyond that grouping.

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

Conciseness3/5

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

The payload is front-loaded in the first sentence, but the remaining sentences include filler: 'Kundli calculator API for astrology apps, matrimonial sites' adds no operational information, and 'Perfect for kundli generation, horoscope matching, and Vedic astrology software integration' largely restates what the tool is. The third sentence on grouping is the only one that earns its keep beyond the opener.

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

Completeness3/5

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

For a 12-parameter tool with an output schema present, the description is functionally adequate — it states what the chart contains, and the schema's rich parameter documentation plus output schema cover the rest. The main gap is that, amid a very large sibling family, it offers no routing guidance and leaves the agent to infer when this is the right tool versus planetary_positions, navamsa, or kp_chart.

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 coverage is 100%, with every one of the 12 parameters carrying a detailed description (date format, time criticality, ayanamsa behavior, focus semantics, compact shape, etc.), so baseline 3 applies. The description adds no parameter-level meaning beyond what the schema already states; the mention of grahas and rashis maps to output, not inputs.

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

Purpose4/5

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

The description states a specific verb and resource — 'Calculate complete Vedic birth chart (Janam Kundli, natal chart)' — and enumerates exactly what the chart contains: all 9 grahas Sun through Ketu plus Lagna, grouped by rashi with nakshatra and pada. The title's 'D1 Rashi chart' helps distinguish it from D9 navamsa and raw planetary-position siblings, though the differentiation is implicit rather than naming any sibling.

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?

It offers use-case context ('Perfect for kundli generation, horoscope matching, and Vedic astrology software integration'), but kundli generation is a tautology of what the tool itself is. No sibling is named and no exclusion is given — an agent is never told when to prefer planetary_positions for raw positions, navamsa for D9, or kp_chart for the KP frame, despite 55+ siblings.

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