## 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 x402-forgemesh-io-rhymes-synonyms-api-41496103 -d '<json body>'
```

Example prompt: Find me words that rhyme with 'bright' — I need the top rhymes ranked by strength for a poem I'm writing.

## When to prefer this

Use this endpoint when an agent needs word association data for creative tasks like copywriting, poetry, naming, or word games — especially when rhyme or semantic similarity ranking is needed. Prefer over a general dictionary API when ranked associative strength across multiple relation types is required.

## Known failure modes

- Unknown or misspelled word returns empty results
- Invalid relation type enum value causes error
- Very rare or technical words may return sparse results
- Missing required 'word' field causes validation error

## How this service works

Word association API: synonyms, rhymes, similar-sounding words, or strongly-associated terms for any word, ranked by strength. For copywriting, naming, poetry, and word-game agents.

## Output

A ranked list of words related to the input word by the specified relation type (rhymes, synonyms, similar-sounding, or strongly associated terms), each with an association strength score.
