## 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-word-associations-lookup-1ffaf18a -d '<json body>'
```

Example prompt: What words are statistically associated with or triggered by the word 'thunder'? Give me the full list of associations.

## When to prefer this

Use this endpoint when you need statistically-grounded word associations (words that people commonly think of in response to a given word) for tasks like brainstorming, copywriting, NLP feature engineering, semantic analysis, or building word games. Prefer this over a thesaurus or synonym API when you want associative/triggered relationships rather than synonyms or hypernyms.

## Known failure modes

- Missing 'word' parameter returns an error or empty result
- Very rare or misspelled words may return few or no associations
- Non-English words may return no results
- Network timeout or upstream Datamuse API unavailability
- Payment failure or insufficient USDC balance for the $0.02 fee
