Example prompt: Can you look up the 24-mountain compass directions used in Feng Shui and tell me which shan covers 195 degrees — including its trigram parent, element, and whether it's yin or yang?

## When to prefer this

Use this endpoint when you need structured Feng Shui compass data — specifically the 24-mountain (二十四山) system with trigram, element, and yin/yang metadata — rather than a generic compass or direction API. Ideal for Feng Shui analysis tools, luopan apps, or BaZi/Chinese metaphysics agents needing fine 15-degree directional resolution.

## Known failure modes

- Degree out of 0–360 range returns no match or validation error
- Unrecognized shan name returns empty lookup object
- Malformed POST body returns 400 error
- Service temporarily unavailable returns 5xx
