Example prompt: Can you evaluate whether my BaZi Day Master is strong, weak, or balanced? I was born on March 15, 1990 at 7am.

## When to prefer this

Use this endpoint when you need to determine the foundational strength polarity of a BaZi Day Master before interpreting luck cycles (大运), annual pillars, or Ten Gods relationships. This is the prerequisite computation for nearly all downstream BaZi analysis — without knowing whether the Day Master is strong or weak, luck cycle and Ten Gods readings are unreliable. Prefer this over generic horoscope or Western astrology endpoints when working specifically within the Chinese Four Pillars (四柱八字) framework.

## Known failure modes

- Invalid or missing birth date/time returns a 400 error
- Unsupported date format causes parsing failure
- Birth hour outside valid Chinese time branch range returns validation error
- Payment not completed (x402 flow) results in 402 Payment Required
- Server-side chart computation failure returns 500 error
