# Maha Celestial Chart Calculator

> Maha Celestial Chart Calculator is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.06/call, status unknown (last checked 2026-09-14).

Calculates a complete UTC astrological chart with Tropical and Lahiri Sidereal positions, whole-sign houses, mean nodes, geometric aspects, and panchanga for a given time and geographic location.

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 maha-celestial-chart-calculator-5577e40f -d '<json body>'
```

Example prompt: Calculate a complete astrological chart — both Tropical and Lahiri Sidereal — for 1985-06-15T14:30:00Z at latitude 40.71 and longitude -74.01, using public data class, and include the integrity receipt digest.

## When to prefer this

Choose this endpoint when you need a fully deterministic, verifiable astrological chart combining both Tropical and Lahiri Sidereal frameworks simultaneously, with whole-sign houses, panchanga, mean nodes, and geometric aspects — especially when an integrity receipt digest is required for auditability. Prefer this over general ephemeris endpoints when you need a comprehensive chart rather than just raw planetary longitudes, or when Vedic (Jyotish) panchanga data is specifically needed alongside Western tropical positions.

## Known failure modes

- Invalid or out-of-range latitude (must be between -89.9 and 89.9) returns a validation error
- Invalid or out-of-range longitude (must be between -180 and 180) returns a validation error
- Malformed or missing instantUtc string returns a parsing error
- Missing required fields (dataClass, instantUtc, latitudeDegrees, longitudeDegrees) returns a schema validation error
- dataClass value outside 'public' or 'synthetic' enum returns a rejection
- Numerical limitation boundaries exceeded for extreme edge cases may return boundary constraint errors
- Payment failure or insufficient USDC balance may result in x402 payment required error

## How this service works

Build a reproducible chart view: Tropical and Lahiri Sidereal positions, Sidereal whole-sign houses, mean nodes, geometric aspects and panchanga for one UTC chart. Includes limitations and a deterministic receipt. Public or synthetic inputs only. No interpretation, forecast or predictive certification; bodies are not stored.

## Output

Returns a versioned JSON object containing Tropical and Lahiri Sidereal planetary longitudes, sidereal whole-sign house cusps, mean node positions, geometric aspects between bodies, panchanga elements, conventions metadata, numerical boundary limits, an input digest, and a deterministic receipt digest for integrity verification. No forecasting narrative or LLM-generated text is included.
