# Vimshottari Dasha Calculator

> Vimshottari Dasha Calculator is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.12/call, status unknown (last checked 2026-09-14).

Calculates Vimshottari birth balance, nine mahadashas, and nine antardashas of the active mahadasha for a given birth instant and reference time using actual nakshatra stay durations and a 365.2425-day year.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vimshottari-dasha-calculator-b80f6bda -d '<json body>'
```

Example prompt: Calculate the Vimshottari mahadashas and the antardashas of the active mahadasha for someone born on March 15, 1985 at 08:30 UTC at latitude 28.6, longitude 77.2 (New Delhi), using today as the reference instant — data class public.

## When to prefer this

Choose this endpoint when you need a deterministic, verifiable Vimshottari dasha computation — including birth balance, full mahadasha sequence, and active mahadasha's antardashas — anchored to a specific geographic location and reference instant, using actual nakshatra stay durations and a 365.2425-day year. Prefer it over generic astrology APIs when you need a cryptographic receipt digest for auditability, strict input/output schemas, and no server-side state retention. Not suitable for event prediction, interpretation, or any LLM-generated astrological commentary.

## Known failure modes

- Missing required fields (instantUtc, latitudeDegrees, longitudeDegrees, referenceInstantUtc, dataClass) return validation errors
- Latitude outside -89.9 to 89.9 or longitude outside -180 to 180 returns schema validation error
- Invalid UTC datetime strings return parsing errors
- Non-public/non-synthetic dataClass values are rejected
- Payment not included or invalid x402 payment header returns payment-required error

## How this service works

Build a Vimshottari timing display with birth balance, nine mahadashas and nine antardashas of the active mahadasha at a reference instant. Uses actual nakshatra stay time and a 365.2425-day year; includes conventions and receipt. Public or synthetic inputs only. No event prediction or interpretation; bodies are not stored.

## Output

Returns a versioned JSON response with offer ID, input digest, computed result containing birth balance, nine mahadashas with boundaries, and nine antardashas of the active mahadasha, along with applied conventions and a deterministic receipt digest. Bodies and receipt digests are not stored server-side.
