## 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 word-tools-collocations-a2dce411
```

Example prompt: What adjectives most commonly describe the noun 'ocean'? Give me the top 10 results.

## When to prefer this

Choose this endpoint when you need statistically grounded word pairings — adjectives for a noun or nouns for an adjective — based on actual corpus frequency. Prefer this over a general thesaurus or synonym lookup when the goal is collocation patterns (words that naturally co-occur) rather than words with similar meanings. Ideal for creative writing assistance, vocabulary enrichment, NLP data augmentation, and content generation tasks that require authentic-sounding word associations.

## Known failure modes

- Missing required 'word' query parameter returns an error
- Invalid mode value (not 'noun' or 'adjective') may return unexpected results or an error
- Limit out of range (below 1 or above 50) may be clamped or rejected
- Uncommon or very rare words may return few or no results
- Payment failure (x402) prevents the request from being processed

## How this service works

Adjectives that commonly describe a noun (ocean: vast, open), or nouns that a given adjective commonly describes.

## Output

A ranked list of up to 50 collocations (words with associated scores indicating collocation strength), along with the mode used, the input word, a summary, source attribution, and optional metadata such as degraded status and disclaimer.
