## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability datamuse-meronyms-lookup-f8944404 -d '<json body>'
```

Example prompt: What are the wholes that the word 'petal' is a part of? Look up its meronym relationships and tell me what larger things it belongs to.

## When to prefer this

Use this endpoint when you need to find the larger whole that a given word is a part of (meronym-to-holonym direction) — e.g., 'petal' → 'flower'. Prefer this over general dictionary APIs when specifically seeking part-whole lexical relationships rather than definitions, synonyms, or antonyms.

## Known failure modes

- Word not found in Datamuse lexicon returns empty array
- Missing 'word' query parameter returns error
- Obscure or highly technical terms may return no holonyms
- Misspelled words may return empty results
- Non-English words typically return no results

## How this service works

Wholes that a given word is a part of (param: word). Query: ?word= Returns JSON.

## Output

A JSON array of words representing the wholes (holonyms) that the input word is a part of — e.g., for 'petal' you might get 'flower'. Each result is a lexical entry from the Datamuse word relationship graph.
