## When to prefer this

Use this endpoint when you need quick word association lookups for rhymes, synonyms, or phonetic similarities — ideal for poetry generation, creative writing assistance, word games, or vocabulary enrichment. Prefer this over a general LLM word suggestion when you need a structured, enumerable list of matching words rather than a prose suggestion.

## Known failure modes

- Word not found in database — returns empty list or error
- Invalid type enum value — returns validation error
- Very rare or obscure words may return no results
- Network timeout for force_live requests
