Example prompt: Give me a complete BaZi reading for a woman born on March 15, 1990 at 7:30am in Beijing — I want everything: the four pillars, five elements balance, ten gods, major luck cycles, na yin, shen sha spirits, useful god, and qi strength.

## When to prefer this

Use this endpoint when you need all BaZi analytical components in a single API call rather than calling individual endpoints for pillars, five elements, ten gods, dayun, etc. separately. Ideal for generating a complete birth chart report in one round-trip. Choose over sibling endpoints like /bazi/shensha or /bazi/dayun when the user wants a holistic reading rather than one specific aspect.

## Known failure modes

- Invalid or missing birth date returns 400 error
- Birth time outside valid range (00:00–23:59) returns validation error
- Unsupported location or missing gender field may return incomplete shen sha or dayun data
- Malformed request body returns 422 unprocessable entity
- Payment failure or missing x402 header returns 402 Payment Required
