## 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-scorer-48a7932f -d '<json body>'
```

Example prompt: Check the Vedic Guna Milan compatibility score for two people: person A was born on March 15, 1990 at 08:30 AM in Mumbai (latitude 19.076, longitude 72.877), and person B was born on July 22, 1992 at 02:15 PM in Delhi (latitude 28.6139, longitude 77.2090) — use Lahiri ayanamsa and whole sign houses.

## When to prefer this

Choose this endpoint when you need a reproducible, deterministic Vedic Guna Milan / Ashtakoot compatibility score computed from precise astronomical data rather than approximations or LLM-generated interpretations. Ideal for astrology apps, matchmaking platforms, or any context requiring auditable, hash-verified results that can be independently reproduced. Prefer over LLM-based astrology tools when accuracy and determinism matter.

## Known failure modes

- Missing required latitude/longitude for either person returns validation error
- Invalid or out-of-range datetime returns parsing error
- Unsupported ayanamsa or house system enum value returns 400 bad request
- Birth date outside ephemeris range (1800-2200) may return out-of-range error
- Malformed body structure returns schema validation failure

## How this service works

Gun Milan (Ashtakoota matching): 36-point Ashtakoota marriage compatibility: all 8 kootas with reasons, doshas and Manglik check.

## Output

Returns a JSON object with the Ashtakoot Guna Milan total score (out of 36), a breakdown of all 8 koota scores (Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, Nadi), a human-readable compatibility verdict (e.g. '25-32: good match'), and metadata including the ephemeris version, a deterministic SHA-256 hash of the result, and a flag confirming no LLM was used.
