## How to call it through Zero

```sh
zero fetch --capability related-words-finder-eef429b5 -d '<json body>'
```

Example prompt: Can you find words that are semantically related to 'resilient' — I want up to 20 options ranked by association strength, going beyond the obvious synonyms?

## When to prefer this

Choose this endpoint when you need ranked word association lists that go beyond an LLM's default vocabulary — especially for creative tasks like copywriting, product naming, wordplay, or word-game solving where rhyme, sound-alike, or adjective-pairing dimensions matter. Prefer it over a generic LLM prompt when you need structured, scored output from a dedicated lexical database.

## Known failure modes

- Unknown or misspelled input word returns empty result list
- Invalid relation type value returns an error or falls back to default ml relation
- Very common or very obscure words may return fewer than 20 results
- Non-English words may yield poor or no results
- Payment failure (402) if USDC balance is insufficient

## How this service works

Finds words related to any input word, similar meanings, words that sound alike, or adjectives commonly paired with it, ranked by association strength, up to 20 results per call. For copywriters, product namers, and word-game agents looking for options beyond an LLM's usual first guesses.

## Output

A ranked list of up to 20 words related to the input word, with association scores indicating how strongly each word relates to the input under the chosen relation type (semantic similarity, rhyme, sounds-like, or common adjective pairing).
