Natal TIAN (天命全息)

Your Whole Self — Eleven Traditions, One Call

Overview

Natal TIAN is askTIAN’s combined natal profile: give it one birthdate and it fans out across eleven of the world’s great birth-chart systems at once — BaZi, Zi Wei Dou Shu, Western astrology, Vedic Jyotish, Human Design, Numerology, Korean Saju, Japanese Shichusuimei, Burmese Mahabote, Twelve Palaces, and the Mayan day-sign — returning each one’s reading in a single response. Instead of calling a dozen endpoints and stitching the answers together, you get a person’s whole metaphysical identity, every tradition’s verdict side by side, from one call.

Origin & history

Each of the eleven systems has its own lineage — the Four Pillars of Song-dynasty China, the Purple Star astrology of Chen Tuan, the Vedic Jyotish of the Indian subcontinent, Hellenistic and modern Western astrology, the contemporary Human Design synthesis, and the Pythagorean roots of numerology. Natal TIAN itself is a modern askTIAN construction: a single orchestrator that runs all of them in parallel from one birth moment, something only computation makes practical.

For most of history a person seeking their full picture would visit a different specialist for each tradition — a BaZi master, an astrologer, a numerologist — each working in isolation, and cross-tradition synthesis was rare and slow. Natal TIAN collapses that into one API call: the same birth data is dispatched to every engine simultaneously, and each returns its native reading, so a developer can present a complete, multi-tradition identity card in seconds.

How it works

Natal TIAN takes a birthdate plus optional birth time and gender (which sharpen the time-sensitive charts like Zi Wei, Human Design, and the Western ascendant) and dispatches it to all eleven natal procedures in parallel. Each system computes independently and returns its own structured result and reading; a failure in one never blocks the others. The askTIAN API returns a systems object keyed by tradition — bazi, ziwei, western, vedic, humanDesign, numerology, saju, shichusuimei, mahabote, twelvePalaces, mayan — each holding that system’s full reading, plus a count of how many ran.

Use cases

Identity Card

Turn a single birthdate into a one-screen profile laying out the person’s BaZi, Zi Wei, Western sign, Vedic chart, Human Design type, Life Path, and more — every tradition at a glance.

Agent User Model

Give an AI agent a rich, structured picture of a person across every metaphysical tradition in one call, instead of orchestrating eleven separate requests.

Cross-System Comparison

Surface where the traditions agree and diverge on one person — a Day Master, an ascendant, a Life Path, a Human Design authority, side by side.

Key terms

Natal chart
A reading computed from a person’s birth moment that maps their lifelong blueprint — the common thread across all eleven systems Natal TIAN runs.
Fan-out
The orchestration pattern where one birthdate is dispatched to many systems in parallel, each returning its own reading, then collected into one response.
Day Master (日主)
The BaZi self-element; one of the per-system signatures Natal TIAN surfaces, alongside the Zi Wei Life Palace, the Western ascendant, and the Life Path number.
Systems object
The keyed result Natal TIAN returns — bazi, ziwei, western, vedic, humanDesign, numerology, saju, shichusuimei, mahabote, twelvePalaces, mayan — each holding that tradition’s full reading.
