For Developers

The sky as
infrastructure.

License the same proprietary Astro Engine that powers Astro Ratan — ephemeris-grade casting, multi-system coverage, edge-aware latency. Built for product teams who refuse to reverse-engineer a calculator from a forum.

Why this page exists

Stop reverse-engineering
a calculator from a forum.

If chart math is core to your product, stitching open-source fragments and hoping ayanamsa defaults match your users is not a strategy. Enterprise access puts the production Astro Engine under your brand — the same brain as our live consumer product.

Reliability for engines people ship on — not a marketing slogan

PARITY

Same story as Technology

No softer enterprise deck. What we claim for the engine here is what we claim everywhere.

Who we expect to hear from

Three kinds of builders.

Astrocorp is a product company with one B2B arm: enterprise access to computation. These are the teams that usually write first.

  1. 01

    Consumer product teams

    You need exact chart casting without standing up an ephemeris team — and without hoping a third-party calculator matches your ayanamsa defaults.

    Cast · transit · latency
  2. 02

    Practitioner platforms

    You are building software for working astrologers. Vedic, KP, and related systems must agree with production consumer math — not a second calculator.

    Multi-system · reports
  3. 03

    Report & workflow builders

    PDFs, journeys, internal tools — places where “almost right” is a liability. Reproducibility matters more than a pretty demo.

    Deterministic · auditable

Capability surface

What you can build on
without owning an ephemeris team.

Exact paths and payloads ship with your agreement. Below is the product language of the surface — natal cast, timing, classical analysis, reports — not a fake OpenAPI dump.

  • Chart cast Natal & divisionals (D1–D60), multi-ayanamsa, house systems.
  • Dashas & timing Vimshottari depth, transit reads, muhurat windows.
  • Classical analysis Yogas, doshas, Ashtakavarga, special lagnas, KP paths.
  • Reports Programmatic report generation used inside our own products.

What we will not blur

Four truths before you email.

  • 01

    Same brain as Astro Ratan

    Enterprise endpoints sit on the production Astro Engine — Swiss Ephemeris core, multi-ayanamsa, multi-discipline. There is no “marketing calculator.”

  • 02

    Not a rented wrapper

    We do not resell a third-party astrology API. Computation is proprietary infrastructure — the same stack under our consumer and professional products.

  • 03

    Conversation speed

    ~50ms class responses from the edge (300+ locations). Built for products that feel like dialogue, not overnight batch jobs.

  • 04

    Honest access model

    No public self-serve sandbox yet. That is quality control. When you get keys, you get contracts you can ship against.

Access model

Enterprise first — on purpose.

There is no public self-serve sandbox yet. That is intentional quality control: when you receive keys, you receive contracts you can ship against.

  1. 01

    Write the use case

    What you cast, expected volume, regions served, and whether you need dashas, muhurat, reports, or full surface access.

  2. 02

    Scope & commercial terms

    We reply with access shape, rate limits, SLA expectations, and commercial structure. Enterprise-first by design — not a public free-for-all.

  3. 03

    Keys & contracts

    Exact API contracts ship with access. Samples on this page are orientation only — not a live sandbox key.

Illustrative shape

What a cast request can look like.

Orientation only. Exact paths, auth, rate limits, and schemas are issued with enterprise access — host surface: api.astrocorp.in.
