Vedic Astrology and Kundli MCP Server by RoxyAPI

Calculate complete Vedic birth chart (Janam Kundli, natal chart) with all 9 planetary positions (Sun through Ketu) plus Ascendant (Lagna). Kundli calculator API for astrology apps, matrimonial sites. Returns accurate graha positions grouped by zodiac signs (rashis) with nakshatra details and pada. Perfect for kundli generation, horoscope matching, and Vedic astrology software integration. Rahu and Ketu are the mean lunar node, referred to the true equinox of date, with Ketu exactly opposite Rahu.

Calculate Navamsa (D9 divisional chart) for marriage compatibility analysis, spouse prediction, and spiritual life assessment. Navamsa calculator API reveals planetary strength in married life. Each planetary position is divided into 9 parts for accurate marriage astrology. Detects Vargottama planets (exalted status). Essential for matrimonial matching, relationship prediction, and marital harmony analysis in Vedic astrology.

Calculate any Vedic divisional chart (Varga) from D2 Hora to D60 Shashtiamsa. Divisional charts divide each zodiac sign into smaller segments to reveal detailed insights about specific life areas: wealth (D2), siblings (D3), property (D4), children (D7), marriage (D9), career (D10), parents (D12), vehicles (D16), spirituality (D20), education (D24), strength (D27), misfortunes (D30), merit (D40), character (D45), and past life karma (D60). Based on Brihat Parashara Hora Shastra (BPHS) Shodasha Varga system. Detects Vargottama planets (same sign in D1 and selected chart).

Calculate detailed Ashtakoot compatibility (Gun Milan) for kundli matching between two people. Returns accurate 36-point Guna Milan scale with breakdown across all 8 kootas (Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, Nadi), Nadi and Bhakoot dosha detection with classical cancellation analysis per Muhurta Martanda and BPHS rules, and marriage recommendation. Perfect for kundli matching for marriage, matrimonial platforms, horoscope compatibility, and Vedic matchmaking services.

Calculate the South Indian ten porutham marriage match (Dashakoot, also called Dasa Porutham) for two birth records. Returns a pass or fail on each of Dina, Gana, Mahendra, Stree Deergha, Yoni, Rasi, Rasyadhipati, Vasya, Rajju and Vedha, a total out of ten, and Rajju and Vedha as explicit hard vetoes that disqualify a match whatever the rest of the sheet reads. This is a different system from the 36 point Ashtakoot Gun Milan on POST /vedic-astrology/compatibility and the two are never reconciled, so a Tamil, Malayalam or Telugu matrimonial desk can read the sheet it actually uses. Direction matters: person1 is the groom and person2 is the bride, because five of the ten poruthams count from the bride birth star to the groom birth star.

Calculate Papasamyam, the balance of malefic (papa) points between two birth charts, for Vedic marriage matching. Counts Mars, Saturn, Sun and Rahu sitting in the afflicting bhavas 1, 2, 4, 7, 8 and 12 read from three reference points in each chart, the Lagna weighted 1, the Moon weighted 0.5 and Venus weighted 0.25, and returns both totals with the graha, the bhava and the weight behind every point. The verdict is a comparison and never a judgement on one person: the bride total must be equal to or below the groom total, so a heavily afflicted groom matched with a comparably afflicted bride reads as balanced while an unafflicted groom matched with an afflicted bride does not. Use it beside Gun Milan and the ten porutham sheet on a matrimonial platform, since a koota score says nothing about malefic balance.

Each period carries its ruling graha, exact start and end dates, and the houses it signifies, with the birth dasha balance and Moon nakshatra that anchor the sequence. This is the top level timeline a Vedic astrology report opens with, and the entry point for drilling into Antardasha and finer sub periods.

Returns the 9 Antardasha sub periods inside a chosen Mahadasha, each proportional to the Vimshottari years of its lord. Every period carries its ruling graha, exact start and end dates, and the houses it signifies, alongside the parent Mahadasha it sits in. Use it to narrow a multi year Mahadasha down to the months that matter for event prediction, muhurta selection, and dasha timeline UIs.

Pratyantardasha calculator API for Vedic astrology. Returns the 9 Pratyantardasha (antara) periods inside a chosen Antardasha, the third level of the Vimshottari dasha hierarchy.

Built for five column dasha drill down tables, muhurta selection, and pinpointing the trigger moment inside an event window already found at the Sookshma level.

The composed Vedic daily reading for one native on one date, in one call. Runs classical Gochara as the gate pipeline the texts describe: the house each transiting graha makes from the natal Moon (Janma Rashi), the vedha pair that can cancel it, the Ashtakavarga bindu gate that decides whether it is delivered, and the Phaladeepika XXVI.30 to XXVI.32 nullifiers, so every graha lands in ONE cited state rather than a bar of a chart. Joined to the panchanga day, which runs sunrise to sunrise with a validity window on every limb, plus tarabala and chandrabala resolved for THIS native as windows rather than as one value, the running Vimshottari chain three levels deep, and a KP finance net over the wealth and loss houses. Ships a hand-reproducible strength score with its arithmetic published in the field itself, and states plainly which part is classical and which part is a RoxyAPI counting convention. Positions are computed in the Lahiri sidereal frame; the KP significators behind the finance area use the KP-Newcomb frame, as they do on every KP route.

Browse the 301-entry Vedic planetary-yoga glossary. Returns id and name for every cataloged yoga (Raja, Dhana, Pancha Mahapurusha, Nabhasa, Chandra-Mangala, and more). This is a dictionary lookup, not chart-driven detection: it does not inspect a birth chart. Use GET /yoga/{id} for the full glossary entry, or POST /yoga/detect to run all 48 detection rules against a specific kundli. Ideal for yoga-browser UIs, search, and progressive data loading.

Look up the dictionary entry for a specific named yoga from the 301-entry Vedic planetary-yoga glossary. Returns formation conditions, life results, and quality classification (Positive/Negative/Both). This is a glossary lookup against the static catalog; it does NOT analyze a birth chart. For chart-driven present/absent verdicts on the 48 detection-grade yogas (Gajakesari, the Pancha Mahapurusha set, all 32 Nabhasa distribution yogas, and the wealth and poverty verdicts) call POST /yoga/detect with birth data.

Chart-driven detection of 48 classical Vedic yogas. Twelve conjunction and dignity yogas: Gajakesari (parashara three-rule definition), Sunapha, Anapha, Dhurdhura, Kemadruma, Chandra Mangala, Budha-Aditya, and the five Pancha Mahapurusha yogas (Ruchaka, Bhadra, Hamsa, Malavya, Sasa). Plus all 32 Nabhasa distribution yogas, which describe how the seven visible grahas are spread across the whole chart rather than any single conjunction, across four families: Asraya (Rajju, Musala, Nala), Dala (Mala, Sarpa), Akriti (Gada, Shakata, Vihaga, Shringataka, Hala, Vajra, Yava, Kamala, Vapi, Yupa, Shara, Shakti, Danda, Nauka, Kuta, Chhatra, Dhanusha, Ardhachandra, Chakra, Samudra) and Sankhya (Gola, Yuga, Shoola, Kedara, Pasa, Damini, Veena). Plus four wealth and poverty verdicts, each ONE answer over a whole family of classical rules: Dhana Yoga over the eleven catalogued wealth combinations of BPHS ch. 41, Daridra Yoga over the poverty combinations of BPHS ch. 42 and Phaladeepika ch. 6, Lakshmi Yoga (BPHS ch. 36), and Dhana Malika (Jataka Parijata ch. 7). Their evidence names every rule that matched and the exact condition it matched on, so a wealth reading cites the combination rather than a label, and a rule resting on a single authority is excluded from the verdict and says so rather than quietly counting. Each yoga is returned with an `id`, `name`, a `present` boolean, a `quality` (Positive, Negative, or Both, i.e. auspicious, inauspicious, or context-dependent), and a classical-text `evidence` string naming the rule that triggered or failed (kendra position, dignity, malefic drishti, lordship, retrograde state, sign modality, bhava distribution). Nabhasa results also apply the four classical precedence norms, so a yoga that matched its own rule but was outranked by a stronger family is returned as absent with evidence naming the norm that silenced it, letting you explain a verdict rather than only report it. There is no separate major/minor flag; `quality` is the auspic

Get the KP-Newcomb (Krishnamurti) ayanamsa for any instant, computed continuously from Newcomb precession theory rather than looked up in a preset table, so it tracks the exact moment you ask for instead of the calendar year. Supply date alone for midnight UTC, or add time and timezone to pin a birth moment exactly. This is the precession offset subtracted from a tropical longitude to obtain the sidereal one, and it is what makes a KP chart reproduce the reference software your practitioners already use. Returns the same value every KP endpoint applies internally. Use it as a dynamic KP Newcomb ayanamsa calculator when you need the Krishnamurti ayanamsa for today, for a birth moment, or for any instant a chart is being rectified against.

Get planetary positions with detailed KP star-lord and sub-lord calculations for precise event timing and significator analysis. Returns all 9 planets (Sun through Ketu) with nakshatra, star-lord, sub-lord, and KP horary numbers (1-249). Essential for KP astrology software, significator analysis, and event prediction.

Calculate ruling planets and their KP significators at regular time intervals using Krishnamurti Paddhati prashna (horary) astrology. For each interval, a full Placidus house chart is erected and significators are computed using the 4-level KP hierarchy: Level 1 (strongest) planets in star of house occupant, Level 2 occupants, Level 3 planets in star of house owner, Level 4 house owner. Returns Day Lord (sunrise-based Hindu Vara), Moon Sign/Star/Sub/Sub-Sub Lords, Lagna Sign/Star/Sub/Sub-Sub Lords, unique ruling planets set, and per-ruling-planet house significations.

Cast a Krishnamurti Paddhati horary chart, also called Prashna, from a number between 1 and 249 given by the querent plus the moment and place the question is judged. NO BIRTH DETAILS ARE NEEDED, which is what makes horary the KP answer when birth time is unknown or unreliable. The number maps to one of the 249 KP sub divisions and sets the Ascendant; the twelve Placidus cusps follow from that Ascendant at the given latitude, and every planetary position comes from the real sky at the moment of the question. Returns the Ascendant with its sub lord, all twelve cusps with star lord and sub lord, the nine grahas placed against those cusps, the five ruling planets for validating the chart, and four-level significators for judging which houses each graha supports. KP horary API, Prashna kundali calculator, 249 horary number chart, Krishnamurti Paddhati horary, cusp sub lord question answering.

A Krishnamurti Paddhati daily finance reading for one native on one date. Four KP layers are each scored against the money houses and weighed into one number: the cusp sub lords of the gain and loss houses (structural promise), the four running Vimshottari lords at the reading moment (timing), the ruling planets of that moment (the pulse), and the sub lord windows the Moon passes through across the civil day (the hour hand), with the best and worst windows named. Weights cusps 30, dasha 40, rulingPlanets 15, moonWindows 15. Every input is the shipped KP arithmetic: Placidus cusps, the 249 sub lord table, the four tier significator rule, the Vimshottari chain to the sookshma level, all in the one ayanamsa you choose. Every row prints its planet, its standing against the two sets and its score, so the number can be audited rather than trusted. The house groups, the classification, the inversion on the loss cusps, the retrograde penalty, the level weights and the layer weights are a KP practitioner convention adopted as the published convention of this route: no classical KP text weighs these four layers against each other, and every table behind the number is printed so the result can be checked line by line rather than trusted. The score measures what the method outputs for the day, never the probability of a gain or a loss. Override the two house groups to run your own school.

Calculate all planetary aspects (Drishti) for a given time. Returns full aspects (7th house for all planets) and special aspects (Mars 4th/8th, Jupiter 5th/9th, Saturn 3rd/10th).

Essential for transit timing, muhurta selection, and monthly astrological forecasting. Monthly planetary aspects API, graha drishti calendar, mutual aspect ephemeris, minor aspects.

Track all lunar aspect events for a given month including major and minor aspects. The Moon traverses approximately 13 degrees per day, forming 22 aspect types with each planet. 5 major (conjunction, opposition, trine, square, sextile) and 17 minor (vigintile, semi-sextile, undecile, semi-quintile, novile, semi-square, septile, quintile, binovile, centile, biseptile, tredecile, sesqui-square, bi-quintile, quincunx, triseptile, quadranovile). Returns exact date and time of each Moon aspect event with ternary search refinement to the minute. Omit year and month to get the month in progress, so a published lunar calendar stays current without a redeploy. Essential for muhurta selection, daily panchang analysis, and chandra gochar predictions. Monthly lunar aspects API, Moon transit calendar, chandra drishti ephemeris, minor lunar aspects.

Analyze planetary transits (Gochar) over natal chart positions. Each transiting graha comes back with TWO whole-sign house numbers, because the two readings answer different questions: houseFromMoon is counted from the natal Moon sign (Janma Rashi), which is the reference classical Gochara uses, and natalHouse is counted from the Lagna. Also returns graha drishti onto the natal grahas (7th for every graha, plus Mars 4th and 8th, Jupiter 5th and 9th, Saturn 3rd and 10th), degree-based angular aspects with orbs, the Gochara Kaksha verdict, and highlighted transits from the slow-moving grahas (Jupiter, Saturn, Rahu, Ketu).

Shadbala calculator API, planetary strength Vedic astrology, graha bala, Ishta Kashta Phala.

Reference list of every avastha (planetary state) across the three classical systems: the five Baladi age states, the three Jagradadi waking states, and the nine Deeptadi dispositional states. Each carries a short label and what the state means for the results the graha can deliver. Use it to turn the bare state names a birth chart returns into readable output, filtered by system if you only need one. Avastha meaning API, Baladi avastha, Jagradadi, Deeptadi, planetary state Vedic astrology.

Look up a single avastha state by its slug, which is the lowercased state name a Vedic birth chart returns in `awastha`, `jagradadi` or `deeptadi`. Returns the system it belongs to, a short label, and what the state means for the results the graha delivers.

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.

Supports both the eight-karaka scheme, where Rahu is included with its degree reversed, and the seven-karaka scheme that excludes the nodes, because the two can name a different Atmakaraka for the same chart. Atmakaraka calculator API, Darakaraka, Jaimini chara karaka, Vedic astrology soul significator.

Calculate Bhava Bala (house strength) for all twelve bhavas per Brihat Parashara Hora Shastra (BPHS) and BV Raman Graha and Bhava Balas. Returns the three classical components (Bhavadhipati Bala from the house lord Shadbala, Bhava Digbala from the rashi class and direction, Bhava Drishti Bala from aspects on the bhava madhya) plus totals in virupas and rupas and a strength ranking. Bhavas are built on unequal Sripati mid-cusps, so a house near a sign boundary is measured where it actually falls. Shadbala measures which graha is strong, Bhava Bala measures which life area is strong, and reading both together is how a practitioner separates a strong planet in a weak house from a weak planet in a strong one. Bhava Bala calculator API, house strength Vedic astrology, bhava bala virupas, Bhavadhipati Bala, Bhava Digbala, Sripati bhava madhya.

Calculate the Bhav Chalit chart, also written Bhava Chalit or Chalit Kundli, placing every graha by unequal Sripati bhava cusps instead of by whole sign. The Rashi (D1) chart treats a whole sign as a house, so a graha a degree from a sign boundary is shown in a house it does not actually occupy; the Chalit chart resolves that by measuring from the bhava sandhis, which is why practitioners check it before reading house results, house lordship strength or transit effects. Returns the twelve bhava boundaries with their madhyas and spans, every graha in both frames, and a moved flag on the placements that differ.
