    Read quick start

Code in minutes. Ship in hours.

One POST with birth date, time and coordinates. The timezone is resolved from the coordinates if you omit it. Every response uses the same envelope with a request ID and calculation version.

  • Authenticate with X-API-Key or a Bearer header
  • Rate-limit headers on every response
  • Clear error codes: INVALID_BIRTH_DATA, AMBIGUOUS_LOCAL_TIME…
curl -X POST 'http://localhost:2579/v1/vedic/kundli' \

Built for accuracy you can prove

Verified precision

Every engine release is regression-tested on golden charts and cross-checked against NASA JPL DE421: planets within 0.2″, the Moon within 0.4″.

Timezones done right

IANA zones with historical offsets and DST. Impossible or ambiguous local times are flagged instead of silently guessed.

Reproducible results

Each response carries its calculation version, so a chart generated today can be reproduced exactly next year.

Secure keys

Keys are hashed at rest, shown once, rotatable with a grace period and revocable instantly. Separate live and test keys.

Pay per call

Transparent credit pricing per endpoint. Test keys are free, failed calculations are never charged.

Developer first

Consistent JSON envelope, request IDs, rate-limit headers and an OpenAPI spec with examples in six languages.

Pay only for what you call

Credits, not subscriptions. Every account starts with 100 free credits; test keys never consume credits, and failed calls are never charged.
