## 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 rotary-agency-datamuse-api-proxy-90362f0a
```

Example prompt: Can you find me 10 words that rhyme with 'silver' and are related to the topic of nature?

## When to prefer this

Use this endpoint when you need lightweight, fast word lookups for rhymes, synonyms, semantic relationships, or phrase completions and want to pay per call via x402 micropayments without setting up a Datamuse API account. Prefer it over direct Datamuse access when operating in an agentic micropayment workflow.

## Known failure modes

- Missing or invalid query parameters return an empty array rather than an error
- Obscure or misspelled input words may return zero results
- Rate limiting or payment failure returns a 402 Payment Required response
- Very broad queries may return a large unranked list requiring client-side filtering
