Tools (30)

• create_chart

  Compute a full Vedic natal chart and cache it, returning a short handle. Call this FIRST. It returns a `chart_id` plus a small summary. Pass that chart_id to the other tools (get_grahas, get_houses, get_current_dasha, get_panchanga, get_yogas) to read specific parts of the chart without recomputing it. Args: dob: Date of birth, YYYY-MM-DD (proleptic Gregorian). tob: Time of birth, HH:MM or HH:MM:SS, 24-hour, local to `tz`. tz: IANA timezone name (e.g. "Asia/Kolkata") or fixed offset "+05:30". lat: Latitude in decimal degrees, North positive. lon: Longitude in decimal degrees, East positive. ayanamsha: Sidereal zero-point — lahiri, raman, kp, true_chitra, yukteshwar, or fagan_bradley. house_system: whole_sign, sripati, equal, placidus, or kp. node_type: "true" or "mean" lunar nodes. transit_date: YYYY-MM-DD the "now" questions are answered against — which dasha is runni

• get_grahas

  Get planetary positions for a cached chart. Args: chart_id: Handle returned by create_chart. planets: Optional list of names to fetch (e.g. ["Moon", "Saturn"]). Defaults to the 9 classical grahas. Also accepts the outer bodies Uranus, Neptune, Pluto, Ceres, Pallas, Juno, Vesta, Chiron. detail: "basic" (default) or "full". Full adds the KP sub-lord and sub-sub-lord, navamsa sign, compound friendships, avasthas, gandanta/pushkara flags, natural karaka and daily motion. Per planet: sign, degrees, nakshatra + pada + lord, house (whole-sign), retrograde flag, and dignity state (exalted/debilitated/own/friend/etc).

• get_houses

  Get the 12 houses (bhavas) for a cached chart. Args: chart_id: Handle returned by create_chart. method: "whole_sign" (default) — sign, lord, lord placement, karaka, occupants. "bhava_chalit" — Sripati/Porphyry cusps with degree spans, which can place a planet in a different house than whole-sign does. "kp_cusps" — Placidus cusps with sub-lords. Always includes an `analysis` block: each planet's functional nature for this ascendant (benefic/malefic/mixed by the houses it rules), plus the Baadhaka and Maraka houses and lords.

• get_current_dasha

  Get the currently-running dasha periods for a cached chart. Returns the active lord at every nested level (Maha -> Antar -> Pratyantar -> Sukshma -> Prana) for each dasha system the engine computed, with the ISO start/end dates of each period. NOTE: "current" is evaluated against the transit date baked into the chart when it was computed, not against today's date at call time.

• get_dasha_periods

  Walk the dasha tree — list periods at any level, past or future. Use this for "when does my next antardasha start", "what runs after this mahadasha", "when was I in Jupiter". get_current_dasha only tells you what is running now; this gives you the whole sequence. Args: chart_id: Handle returned by create_chart. system: vimshottari (default), yogini, ashtottari, or chara_jaimini. within: Drill down by naming the enclosing lords, outermost first. None (default) lists the mahadashas. ["Sun"] lists the antardashas inside the Sun mahadasha. ["Sun", "Mercury"] lists the pratyantardashas inside that antardasha. Chara Jaimini is keyed by rashi name rather than graha. Each period carries lord, ISO start/end, duration in years, and whether it is the one currently running.

• get_timeline

  Get the turning points between two dates — dasha changes and slow-planet ingresses. This is the two-clocks view: the dasha sequence counted from birth (which theme is switched on) against gochara, the real sky on that date (the trigger). Use it for "what happens in the next five years", "when does this period change", "when does Saturn cross my Moon". get_dasha_periods answers when one clock changes; this answers when both point at the same thing. Every date is exact, bisected against the ephemeris to the day — not a sampled approximation. Args: chart_id: Handle returned by create_chart. The birth data is reused; the range below is independent of the chart's transit_date. start_date: YYYY-MM-DD, inclusive. end_date: YYYY-MM-DD, after start_date. systems: Dasha systems to include — vimshottari, yogini, ashtottari, chara_jaimini. Defaults to all four. Antardasha changes are reported for

• get_lagna_points

  Get the chart angles, special lagnas, Arudha padas and Bhrigu Bindu. Beyond the ascendant: MC/IC/Descendant/Vertex, the time-based special lagnas (Bhava/Hora/Ghati/Sree/Indu), the Jaimini Arudha padas (AL, A2-A12, Upapada) and Bhrigu Bindu. Special lagnas whose rate is school-divergent are reported under `not_computed` with a reason rather than guessed.

• get_panchanga

  Get the birth panchanga (the five limbs of the Vedic calendar). Returns tithi (lunar day + paksha), vara (weekday), nakshatra, yoga, and karana at the moment of birth, plus the lunar month and season.

• get_yogas

  Get the yogas (classical planetary combinations) present in a chart. Only yogas whose rule actually tested true are listed, each with the rule that matched. An empty list is a real result — it means none of the implemented yogas are present in this chart, not that the check was skipped.

• get_varga

  Get one divisional chart (varga) from a cached chart. Args: chart_id: Handle returned by create_chart. varga: Which divisional chart, e.g. "D9" (navamsa), "D10" (dashamsa), "D11", "D60". See describe_chart -> varga_coverage for the full list of what this engine computes and what it deliberately does not. Returns the varga ascendant and each planet's sign in that chart. Where a varga's counting scheme diverges between schools, the scheme actually used is reported in `method` — do not assume it matches your tradition.

• get_vimsopaka

  Get Vimsopaka bala — each planet's dignity-weighted strength across the 16 vargas. Use this to answer "which planets are strong across the divisional charts?" A planet in its own or exalted sign in all sixteen scores the full 20. Returns the score, the ceiling actually applicable, and an interpretive band. The score is the classical quantity; the band labels are a convention laid over it and are tagged as such.

• get_strengths

  Get Shadbala, Bhava Bala and Ishta/Kashta phala — how strong each planet and house is. Call this for "which planet is strongest", "is Saturn strong enough", or "which houses are weak". Shadbala is the six-fold Parasari strength; a planet meets expectation when `ratio` >= 1. Read `ratio` (>= 1 means the planet clears its own bar) and `rank_by_ratio` when saying a planet is strong or weak; the summary's `meets_requirement` lists every planet that qualifies. Each planet has its own `required_rupa`, so plain `rank` (absolute `total_rupa`) frequently disagrees: a planet can clear its own bar and still rank low overall. Use `strongest_by_ratio` / `weakest_by_ratio` for interpretation; the bare `strongest` / `weakest` keys are absolute-rupa based and kept only for backward compatibility. Args: chart_id: Handle returned by create_chart. detail: "summary" (default) gives totals, both ranks, ratio and Ishta/Kashta per pla

• get_ashtakavarga

  Get Ashtakavarga bindus — the point-score each sign carries, used for transit strength. Call this for "is this a good sign for Saturn to transit" or "which signs are strongest overall". Sarvashtakavarga (SAV) sums the seven planetary charts; the classical pre-reduction total is always 337. Args: chart_id: Handle returned by create_chart. planet: Restrict the per-planet (Bhinna) charts to one graha. include_sodhana: Add the trikona/ekadhipatya reductions and Shodhya Pinda. Off by default — it roughly triples the response.

• get_aspects

  Get planetary and sign aspects — who is looking at which house. Graha drishti is the Parasari planetary aspect (everything aspects the 7th; Mars, Jupiter, Saturn and the nodes have special aspects). Rasi drishti is the Jaimini sign aspect, a different system — do not merge the two. Args: chart_id: Handle returned by create_chart. planet: Restrict graha drishti to one graha. include_argala: Add Argala and Virodhargala (Jaimini intervention). Off by default — it roughly doubles the response.

• get_karakas

  Get the Chara (Jaimini) karakas plus Karakamsa and Swamsa. The Atmakaraka — the planet at the highest degree in its sign — is the single most-used significator in Jaimini analysis. Returns the whole ladder in descending degree order, plus the natural (naisargika) karakas. Note Rahu's degrees are counted in reverse, so its `effective_degrees` will differ from its actual position.

• get_transits

  Get gochara — where the planets are now relative to the natal chart. Answers "is Sade Sati running", "is Jupiter transiting well", "is today favourable". Houses are counted from BOTH the natal Moon (the classical reference for gochara) and the natal Lagna. IMPORTANT: transits are computed for the chart's `as_of` date, which is the transit_date it was created with — not today unless the chart was created today. Pass transit_date to create_chart to ask about another date.

• get_day_periods

  Get sunrise/sunset and the auspicious/inauspicious windows of the BIRTH day. Rahu kala, Yamaganda, Gulika kala, Abhijit and Brahma muhurta, plus true sunrise/sunset, day length and whether the birth was by day. IMPORTANT: these are the windows for the DATE OF BIRTH, not for today. This tool cannot answer "when is Rahu kala today" — that needs a chart created for today's date.

• get_avasthas

  Get planetary avasthas — the maturity, alertness and mood states of each graha. Baladi is the age state (infant..dead) and scales a planet's ability to deliver. Jagradadi is awake/dreaming/sleeping. Deeptadi is the mood from exaltation down to combustion. Two further ladders, lajjitadi and sayanadi, are deliberately NOT computed — their conditions are school-divergent — and are reported as deferred rather than guessed.

• get_fixed_stars

  Get conjunctions between the grahas and named prominent fixed stars. Returns only real conjunctions within the configured orb, plus what was scanned. An empty `conjunctions` list is a provable negative, not a skipped check — `planets_scanned` and `stars_scanned` show the search that ran.

• get_longevity

  Get Ayurdaya (longevity) estimates — EXPERIMENTAL, not for predictive use. The engine computes Pindayu and Nisargayu, but flags the whole section experimental: the classical methods are textually divergent and the reduction rules are only partially applied. The disclaimer is returned with the numbers and must be passed on to the reader, not dropped. Do not present these as a lifespan prediction.

• get_compatibility

  Calculate 36-point Ashta-Kuta Guna Milan compatibility between two charts. Evaluates all 8 classical Parashari Kutas (Varna, Vashya, Tara, Yoni animal intimacy, Graha Maitri, Gana, Bhakoot, and Nadi) plus a Kuja Dosha (Manglik) mutual cross-audit between Person 1 and Person 2.

• get_doshas

  Audit classical Vedic doshas: Kuja Dosha (Manglik), Kaal Sarp, Gandanta, Pitre. Evaluates Mars placements from Lagna, Moon, and Venus with 8 classical cancellation exceptions, 12 Kaal Sarp variants, Gandanta junctions, and Pitre dosha indicators.

• get_numerology

  Calculate Chaldean Name Numerology and Vedic Date of Birth numbers. Calculates Name Number (compound + root), Birth Number (Mulank), Destiny Number (Bhagyank), ruling planetary archetypes (Swami Grahas), and harmonic resonance.

• get_prompt_library

  Fetch curated high-value prompt templates and multi-tool question workflows. Call this tool whenever you want to suggest high-value questions to the user, or when the user asks "what can you do?", "what should I ask?", or wants guided astrology workflows (e.g. Sade Sati analysis, timeline forecast, dasha transitions, chart strength, school comparisons, timing windows). Args: category: Optional category filter. One of 'all', 'Core Reading', 'Timing & Transits', 'Career & Wealth', 'Strengths & Accuracy', 'Relationships', 'Daily & Remedies'. Names are matched case-insensitively; an unrecognised one is an error listing the valid names, never a silent empty result. include_full_templates: Set to True to retrieve the full expanded prompt text. Defaults to False for compact workflow titles and tool chains. Returns a structured catalog of prompt templates with their titles, descriptions,

• describe_chart

  Get metadata and an inventory of what a cached chart contains. Useful for orienting before drilling in: returns the birth data and config it was computed with, the top-level sections available in the document, and how many fields the engine honestly marked as deferred or uncomputable.

• rectify_birth_time

  Test how much a recorded birth time can actually be narrowed, and against what. Two modes: * **No events** — scans the uncertainty window and reports how many genuinely distinct charts it contains, what differs between them, and what does not. Use this FIRST to find out whether rectification is even worth attempting. * **With events** — scores each candidate against dated life events and checks the result against a null model of randomised dates. This tool does NOT return "your real birth time is X", and you should not present it that way. The unit of the answer is the **variant** — a group of minutes producing an identical chart structure. Preferring one minute over its neighbour inside a variant is fitting arithmetic, not evidence. Read `verdict.usable` before quoting anything else. Fewer than three independent, well-dated events fits the events rather than the birth time, and the verdict will say so. Args:

• get_account_status

  Check the calling account's plan, remaining chart credits, and what is gated. Call this BEFORE attempting a tool that might be refused, not after. It is to subscription limits what describe_chart is to chart sections: the index you consult to find out what is reachable, so a paywall is something you can plan around rather than something you discover by hitting it. `credits_remaining` is the number of chart *computations* left this month — reading a chart you already created costs nothing, so the count falls only when new astronomy is calculated. `gated_tools` lists what the current plan cannot reach, and is empty on a paid plan.

• health_check

  Check whether this server is correctly configured and computing accurately. Reports the ephemeris mode actually in use, engine versions, and cache state. Call this when chart positions look wrong or disagree with another source: the usual cause is a missing ephemeris directory, which degrades the engine to an approximation without failing. `status` is "ok" when the Swiss ephemeris is complete, "degraded" when the engine is running on the Moshier fallback.

• server_stats

  Get usage metrics for this server session: calls, latency, errors, payload size. Per tool: call count, p50/p95/max latency, average and peak response size, and how many responses exceeded the payload budget. Plus cache hit rate and a breakdown of errors by type. Counters are per-process and reset when the client restarts the server.

• calculate_birth_star

  Compute just a person's Vedic birth star (nakshatra) and core anchors. A one-shot shortcut: use this when the birth star is the whole question. If you expect follow-up questions about the same person's chart, prefer create_chart, which caches the full chart behind a reusable handle. Args: dob: Date of birth, YYYY-MM-DD (proleptic Gregorian). tob: Time of birth, HH:MM or HH:MM:SS, 24-hour. tz: IANA timezone name (e.g. "Asia/Kolkata") or fixed offset "+05:30". lat: Latitude in decimal degrees, North positive. lon: Longitude in decimal degrees, East positive. ayanamsha: Sidereal zero-point. Default lahiri. Returns the birth star (Moon's nakshatra), its pada and ruling planet, the Moon sign, the ascendant, and the Sun's nakshatra.
