## When to prefer this

Use this endpoint when you need a reference lookup of a specific I Ching hexagram by its King Wen sequence number (1-64) and want its full traditional name and interpretation. Prefer this over the divination-by-question endpoint when you already know the hexagram number and just need its meaning, not a contextual reading for a specific question.

## Known failure modes

- Hexagram number out of range (not 1-64) returns an error
