Every product on this page already exists as an industry: kundli matching on matrimony platforms, panchang and rashifal columns in newspapers, festival-season retail, naming consultancies, calendar-driven scheduling. What DevDarsha changes is the build cost. The Panchang API answers when, the Horoscope API answers what a birth chart shows, the Numerology API answers what a name and date compute to — each as deterministic JSON behind one gateway.
Which day carries which tithi, nakshatra, and festival? Where do the traditional timing windows fall? Calendar and scheduling questions live here.
What does a birth chart contain — its planetary positions, running dasha, doshas, and how two charts score in Ashtakoot matching? Chart questions live here.
What do a name and birth date compute to in Pythagorean or Chaldean numerology? Which personal cycle is active? Number questions live here.
The three APIs sit behind one gateway and one authentication model, but each answers a different class of question and each carries its own plan, quota, and entitlements. Pick the engine that matches your product's core question; combine them when the product spans more than one.
Full panchang for any supported city and date: tithi, nakshatra, yoga, karana, traditional timing windows including Rahu Kalam, sunrise, and a 500+ festival database with multi-faith filtering.
Deterministic Vedic Jyotish from birth details: Rashifal, Kundli, Vimshottari Dasha, divisional charts (D1 and D9), dosha analysis, and Ashtakoot matching as versioned JSON.
Pythagorean and Chaldean numerology with the system always stated explicitly — core profiles, name analysis, personal cycles, compatibility, Lo Shu grids, reports, correction, and bulk runs.
None of these are hypothetical. Each card maps an existing market — one where users already pay for panchang, kundli, or numerology content — to the exact endpoints that power it, including where two or three engines combine.
Kundli matching is a standing feature of the Indian matrimony industry — profiles routinely list guna scores. Compute Ashtakoot matching and dosha screening on every profile pair, offer a numerology compatibility reading as a second lens, and once a match is made, give families monthly Panchang timing data for wedding-date review. The scores are calculations for users and their astrologers to weigh — the decision stays with them.
See matching endpoint →Call-an-astrologer platforms are one of the fastest-growing consumer categories in India. Their working screen needs the client's kundli, running dasha, and D9 chart generated before the call connects, plus today's panchang for the astrologer's reference — and a numerology profile for consultants who read both. Deterministic JSON means every astrologer on the platform sees the same chart for the same birth details.
See kundli endpoint →The daily panchang column and the twelve-sign rashifal are fixtures of regional print and digital media. Auto-generate both: one /daily call per city for the panchang column, one /rashifal call for the sign forecasts. Panchang responses serve at P50 <50ms when cached, India region, gateway-measured — fast enough for live pages.
See rashifal endpoint →Naming a child with reference to the birth nakshatra and the name's numbers is long-standing family practice. Generate the birth kundli to surface the nakshatra, then compute each candidate name's numbers in Pythagorean, Chaldean, or both — with the system always stated. Your app presents the traditional inputs; the family makes the choice.
See name endpoint →Brand-name numerology and tradition-aware launch dates are an established consulting trade — founders routinely pick company names and opening dates with an advisor. Productise the workflow: run candidate brand names through name analysis and correction, then attach monthly Panchang data — tithi, festivals, and timing windows — for launch-date planning.
See numerology docs →Auto-generate puja schedules and festival calendars from the 500+ festival database. Multi-faith filtering keeps Vaishnavite, Shaivite, Jain, Sikh, and Buddhist calendars correct and separate — one platform can serve a Gurdwara's Gurpurab calendar and a temple's Ekadashi list from the same integration.
See faith filter →Dhanteras, Akshaya Tritiya, and Dussehra move real sales volume in gold, electronics, vehicles, and clothing every year. Pull the coming month's festivals and tithis once, schedule campaigns against them, and localise by city — the merchandising calendar writes itself from the data.
See monthly endpoint →Self-discovery apps already sell personal-year readings and period overviews as reflective content. Serve personal cycles and full numerology reports alongside dasha timelines and structured forecasts — as journaling prompts, reflection material, and practitioner workflow support. Computed and repeatable: the same inputs always produce the same reading.
See cycles endpoint →Indian enterprises plan operations around the religious calendar: regional festival holidays, office event dates, and corporate puja schedules. Pull a year of festivals and timing data in one yearly batch, cache it in the HRMS or ERP, and drive holiday calendars and event scheduling with zero live lookups — a calendar layer, nothing about evaluating people.
See yearly endpoint →Ekadashi fasting alerts, full-moon reminders, festival-morning pushes, and Rahu Kalam window notices are the daily-retention backbone of devotional apps. Pre-generate a month of trigger events from one monthly call; add personal-cycle transitions from numerology for individualised nudges.
See monthly endpoint →Hindu, Jain, Sikh, and Buddhist communities abroad keep their observances on local time. Coordinate lookup and timezone override deliver sunrise-anchored panchang for cities worldwide, faith filtering matches each community's tradition, and rashifal keeps the daily-forecast habit alive far from home.
See city & coordinate docs →Agencies and SaaS builders ship the same astrology or numerology feature to many clients. Bulk numerology processes name-and-date lists in one call for list-scale products, while batch panchang endpoints feed white-label calendar surfaces and kundli generation serves each end user — you own the brand and the UI, the engines do the computation.
One gateway and authentication model, with product-isolated plans, quotas, and entitlements — and consistent JSON contracts across Panchang, Horoscope, and Numerology, so adding a second engine to your product is a new endpoint call, not a new vendor.
The same gateway, authentication model, and account work across all three APIs. Each product keeps its own plan, quota, and entitlements.
No LLM in the computation path. Same birth details, same name, same date — same JSON every time, on every plan.
5,681 cities, 500+ festivals, multi-faith filtering, explicit ayanamsa and numerology systems — the domain details are the product.
From a one-day prototype to a full multi-engine platform, the same three APIs work at every level of product maturity — start on a free tier, expand endpoint by endpoint, and never rewrite.
Embed today's panchang, a sign-of-the-day rashifal, or a name-number calculator into any page. One key, one endpoint, a handful of fields.
A timing-aware date picker, an instant kundli viewer, or a baby-name shortlister. Fetch batch data once, cache it, and put a clean UI in front of it.
Matrimony matching pipelines, astrologer marketplaces, enterprise calendar layers, bulk list processing — combining engines behind your own product surface.
