Choose this endpoint when you need a structured, machine-readable list of synonyms for a specific word, especially in automated writing, content enrichment, NLP pipelines, or vocabulary expansion tasks. Prefer this over general language model synonym generation when you want a curated, lexicographic data source (Datamuse) rather than probabilistic suggestions.

- Word not found in Datamuse database returns an empty array
