What you get

Every astrology primitive you'd build from scratch — in one API.

Stop bundling Swiss Ephemeris into your container. Stop maintaining ayanamsha tables. Call the API, get JSON back.

Natal charts

Tropical or sidereal. Lahiri / Krishnamurti / Raman ayanamshas. Placidus / Whole-Sign / Equal house systems. Planets, retrograde flags, daily speeds.

Talent profiles

60+ astrological skills scored from the chart. Use for product onboarding, HR matching, gamified self-discovery.

Pair compatibility

Western synastry + Vedic Ashtakoota in one call. Aspect-by-aspect breakdown plus a single overall verdict score.

PDF reports

Generated async, delivered via signed S3 URL. Branded HTML templates so the file looks like your product, not ours.

AI interpretations

Template-grounded narratives in 4 tones (caring / pragmatic / mystical / corporate). LLM cost cap per tenant — no surprise bills.

Production-grade

OAuth-style scopes, opaque api-keys (argon2id), full audit log, per-tenant rate limit + quota, OpenAPI spec, OpenTelemetry traces.

For developers

Five-line integration. Same shape in every language.

The API speaks JSON, ships a typed OpenAPI spec, and has a single bearer-token auth model — your existing HTTP client works.
