AstroNest Developer API

Muhūrta API

Describe the event in plain words ("signing a lease", "griha pravesh") or pick an event type, give a date range, the place it happens and the birth data of the person it is for, and get windows ranked for that person.

The pañcāṅga is computed where the event happens, never defaulted to the birthplace.

Why AstroNest

Deterministic interpretation

Interpret, guidance, compatibility and guna milan call no language model: the same chart always gets the same reading. Only forecast and timing are voiced by a model, and they are marked as such.

Muhūrta at the event's place

The pañcāṅga for a muhūrta is computed where the event happens, never defaulted to the birthplace.

Pricing

Sandbox keys are free, with no time limit, and return the samples above. A live key starts with 100 free credits; after that you buy credit packs. Each endpoint's cost in credits is shown above. Pricing

Questions

Where is the pañcāṅga computed?
At the event's place, which you send separately from the birthplace.
Do I need the person's birth data?
Yes. Windows are ranked against the chart of the person the event is for.

Readings are symbolic interpretation, not medical, legal, financial or psychological advice.
