What it does

For each seed word and a chosen relation type, it returns ranked related words with a relevance score, syllable count and part-of-speech tags — one row per word, ready for spreadsheets or keyword pipelines.

Input

Field	Type	Description
`words`	array	Seed words (one lookup per word).
`relation`	string	`means_like`, `synonyms`, `rhymes`, `near_rhymes`, `sounds_like`, `spelled_like`, `triggers`, `antonyms`, `followers`, `predecessors`.
`maxResults`	integer	Words per seed (1-1000, default 20).

Output (one item per word)

{
  "seed": "ocean",
  "relation": "means_like",
  "status": "found",
  "word": "sea",
  "score": 40041792,
  "num_syllables": 1,
  "tags": ["syn", "n"]
}

Every input yields at least one item, with status: found, not_found, or error.
