# Astro Agents Vedic Gun Milan Compatibility API

> Astro Agents Vedic Gun Milan Compatibility API is a paid API for AI agents from astro-agents-api.vercel.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-15).

Calculates Vedic astrology Kundali Gun Milan (Ashta Koota) compatibility score between two people using NASA/JPL DE440 ephemeris, returning reproducible point totals across 8 compatibility categories.

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 astro-agents-vedic-gun-milan-compatibility-api-59021404 -d '<json body>'
```

Example prompt: Can you calculate the Vedic Gun Milan compatibility score for two people — person A born on March 15, 1990 at 08:30 AM in Mumbai (19.076° N, 72.877° E), and person B born on July 22, 1992 at 11:45 AM in Delhi (28.644° N, 77.216° E) — using Lahiri ayanamsa and whole sign houses?

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible Vedic astrology Kundali Gun Milan (Ashta Koota) compatibility score computed from first principles using the NASA/JPL DE440 ephemeris — especially when auditability (via SHA-256 hash), no LLM involvement, and Vedic-specific metrics (nadi, gana, yoni, etc.) are required. Prefer this over Western astrology compatibility endpoints or LLM-generated horoscopes when the user expects classical Vedic marriage matching standards.

## Known failure modes

- Missing required latitude/longitude for either person returns a validation error
- Invalid or missing birth date/time causes computation failure
- Unsupported ayanamsa or house system enum value returns a 400 error
- Birth datetime outside ephemeris range (1800-2200) may return an out-of-range error
- Malformed request body or incorrect bodyType triggers a schema validation error

## How this service works

Deterministic Western + Vedic astrology API for AI agents: JPL DE440 ephemeris, no LLM, reproducible SHA-256 hashes.

## Output

Returns a JSON object with the total Gun Milan points out of 36, a breakdown of all 8 Ashta Koota scores (gana, nadi, tara, yoni, varna, vashya, bhakoot, graha maitri), a human-readable verdict (e.g. '25-32: good match'), engine metadata confirming no LLM was used, the ephemeris version, and a SHA-256 hash for result reproducibility verification.
