Tutorials, integration guides, and deep-dives for developers building astrology apps with JavaScript, Flutter, Python, and more.
Plot and room polygons in; zone map, Brahmasthan check and sourced rule findings out. A real POST /vastu/plan/analyze request and response, field by field, plus what the API deliberately does not do.
Exact degree ranges for the 4, 8 and 16 direction systems, the deity of each direction, how a bearing on a boundary is classified, north_angle, and why the East zone of a wide plot is four times the North zone.
Plot proportions, irregular plots, the Brahmasthan and the main entrance: how each check works, what the findings mean, how to compare candidate entrances with /vastu/findings, and how to check a griha pravesh date.
house_system=placidus on any Vedic chart endpoint. Real quadrant house-cusp math via Swiss Ephemeris, not a sign-offset approximation. Whole Sign stays the default.
GET /extended-horoscope/combustion returns which planets are combust using classical BPHS orb thresholds, cross-verified across independent sources.
The ecliptic × prime-vertical intersection point Western relationship astrologers use in synastry — the "fated encounters" point, independent of house system.
Each of the 7 classical planets' 1-36 diurnal-circle sector, the technique behind Gauquelin's statistical research on planetary prominence.
Ascending/descending node and perihelion/aphelion for Mercury through Pluto — real heliocentric orbital elements, verified against published data.
The next time the Moon occults a planet at a given location, with contact times — live-verified against a real 2026 Moon-occults-Venus event.
Add &lang=hi to any API call and get सूर्य instead of Sun, மேஷம் instead of Aries. Static lookup (no AI call), Sanskrit romanization included.
A real demo of AI chart interpretation output — 700+ words, chart-specific, BYOLLM. What it means for developers building AI astrology products.
Sidereal vs tropical, house systems, what Rahu and Ketu are, why the same birth date returns different Sun signs — everything a developer needs to understand the difference.
fetch(), axios, Next.js App Router, React hooks, Express — complete copy-paste code examples for calling the Vedic astrology API from any JavaScript environment.
Build a production-ready Vedic astrology app with Flutter and dio. Dart model classes, FutureBuilder screens, kundali chart, panchang, dasha — everything to ship on Play Store.
fetch, Expo SecureStore, DateTimePicker, and a complete kundali screen component — everything to ship a Vedic astrology app for iOS and Android using React Native.
SSE streaming, multi-turn conversation history, React chat component, embeddable widget — everything to ship an AI astrologer chatbot powered by AI (BYOLLM) and real chart data.
Step-by-step tutorial: fetch daily sun horoscope, panchang, and current dasha in a React app. Complete with code and a free API key.
Why JHora uses mean node, what happens to divisional chart placements when you use true node instead, and how the node choice changes the divisional placements that match JHora.
Divisional chart formulas, Vimshottari dasha cycle loops, and sunrise/sunset approximations. A technical deep-dive into what accuracy actually means for a production astrology API.
The full methodology: reference chart, JHora 8.x, 71 data points across planets, divisional charts, and dashas — and the fixes required to reach zero discrepancies.
Checked against Drik Panchang for New Delhi, 2026: 12/12 Amavasya, 13/13 Purnima, 24/24 Ekadashi and 19/19 major festival dates match; all 98 published tithi start and end times within 2 minutes; 2026 new and full moons within 40 seconds of the US Naval Observatory.
A subtle double-timezone conversion bug causes dasha start dates to shift by hours for non-IST users. How to identify it, reproduce it, and fix it correctly.
What Swiss Ephemeris is, why it is the industry standard for astronomical computation, and why running it locally (not via a third-party API) is the only way to guarantee accuracy and uptime.
What divisional charts are, BPHS-correct computation, and how to fetch any chart from D1 to D60 — with a complete reference table of all 15 commonly used varga charts.
App Router API routes, Server Components, caching strategies, and a complete birth chart page — everything to integrate the Vedic astrology API into a production Next.js app.
Use requests to fetch a complete birth chart. Covers authentication, parsing planet positions, and building a CLI tool that prints a formatted kundali.
Integrate north-style and south-style kundali matching into a matrimony or dating app. Full guna milan breakdown, rajju-vedha, and aggregate score — all in one API call.
A complete guide to the guna milan algorithm: the 8 koota factors, scoring methodology, rajju-vedha check, and how to present results clearly to non-technical users.
Tithi, Nakshatra, Yoga, Karana, Vara, Rahu Kaal, Choghadiya — everything the panchang endpoint returns and how to display it beautifully.
What the dasha system is, how it is calculated, and how to surface current mahadasha, antardasha, and sub-period data in your application using the API.
Users text their birth details and receive a personalized kundali summary. Full Node.js implementation with Twilio WhatsApp API and VedIntel astrology endpoints.
file_get_contents, cURL, Guzzle, and a complete WordPress shortcode plugin with transient caching — full PHP integration for the VedIntel™ AstroAPI in any PHP framework.
VedicAstroAPI, Vedika, Prokerala, AstrologyAPI, RoxyAPI, and VedIntel™ — compared by endpoint count, computation engine, AI capabilities, and price per call.
Complete code-level migration. Same endpoint paths, same parameter names, same response envelope. Change one environment variable.
From daily horoscope widgets to kundali matching bots to AI reading generators — 10 concrete app ideas, each with the exact endpoints needed and a realistic build time.
Subscription, per-report, credit packs, white-label B2B — how astrology developers structure pricing, what margins look like, and which model works at which scale.
Every nakshatra, its lord, its pada system, and how to use nakshatra data from the API to build personalization features — compatibility, muhurta, and vastu.
What Mangal Dosha is, how it is computed from house placements, the seven types, and how to expose it cleanly in a matrimony or astrology app.
What Sade Sati is, how it is calculated from the Moon sign, the three phases (rising, peak, setting), and how to build a high-engagement Saturn transit feature in your app.
