# AstroM8 API

> Production astrology infrastructure for calculations, content, and branded reports.

AstroM8 gives products a consistent API surface across Western, Vedic, Thai, Chinese, and Korean astrology. Start with deterministic calculation endpoints, then add paid interpretation and report delivery only where your product needs them.

## What you can build

* **Western workflows:** natal, synastry, composite, returns, progressions, and transit windows.
* **Vedic workflows:** Panchang, divisional charts, Vimshottari dasha, matching, yogas, Ashtakavarga, Varshaphal, and remedies.
* **Regional workflows:** Thai calendar and muhurta, BaZi, Qi Men Dun Jia, and Korean Saju.
* **Customer outputs:** horoscope feeds, tarot and numerology, branded PDFs, and chart images.

All public endpoints use an API key. Each endpoint declares its tier and credit behavior in the reference; call the estimate endpoint before an expensive operation when you want to show cost before submitting it.

## Public contract

This portal documents every customer-facing AstroM8 workflow. Calculation and enterprise endpoints use an API key; customer report delivery and branding operations use the session bearer token documented in their reference entries.
