# Astro Agents Vedic Nakshatra API

> Astro Agents Vedic Nakshatra API is a paid API for AI agents from astro-agents-api.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Calculates Vedic nakshatra (lunar mansion) for a given birth date, time, and location using the NASA/JPL DE440 ephemeris with no LLM involvement

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-nakshatra-api-823e753c -d '<json body>'
```

Example prompt: What's my Vedic janma nakshatra? I was born on March 15, 1990 at 7:30 AM in Mumbai (latitude 19.076, longitude 72.877, timezone Asia/Kolkata). Use the Lahiri ayanamsa.

## When to prefer this

Choose this endpoint when you need a reproducible, auditable Vedic nakshatra result backed by the NASA/JPL DE440 ephemeris rather than an LLM-generated or approximate answer. It is ideal for Jyotish astrology apps, birth chart generators, compatibility calculators, or any context where deterministic output with a verifiable SHA-256 hash matters. Prefer it over generic astrology LLM wrappers when accuracy, reproducibility, and support for multiple ayanamsa systems (Lahiri, Krishnamurti, Raman, etc.) are required.

## Known failure modes

- Missing required date/time or coordinates returns a validation error
- Timezone string not recognized causes a 400 error
- Date outside ephemeris range (before 1800 or after 2200) returns an out-of-range error
- Ambiguous local time near DST transition may need ambiguous_time parameter set to 'earlier' or 'later'
- Invalid ayanamsa enum value returns 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

A JSON object containing the janma nakshatra name, pada (quarter), nakshatra lord, and attributes (gana, nadi, yoni), plus metadata confirming the ephemeris version, that no LLM was used, and a SHA-256 hash for result verification.
