## 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 forgedmesh-define-word-api-92988e48 -d '<json body>'
```

Example prompt: What does 'ephemeral' mean — give me all its senses labeled by part of speech, how to pronounce it, and a list of synonyms and antonyms.

## When to prefer this

Choose this endpoint when you need definitions, pronunciations, and synonym/antonym data for an English word in a single API call — ideal for writing assistants, tutoring bots, and content pipelines that would otherwise need to chain multiple dictionary and thesaurus queries.

## Known failure modes

- Word not found in dictionary — unknown or misspelled word returns empty or error response
- Non-English words may return no results
- Very technical jargon or neologisms may have incomplete entries
- Payment failure (insufficient USDC balance) returns 402 error

## How this service works

Get dictionary definitions for a word — all senses labeled noun/verb/adjective, with pronunciation guide and a synonym/antonym list attached. One call replaces a definition query, a thesaurus query, and a spell-check: useful for writing assistants, tutoring bots, and content pipelines.

## Output

A structured response containing all dictionary senses for the queried word, each labeled with its part of speech (noun, verb, adjective, etc.), a pronunciation guide, and a combined synonym and antonym list — replacing separate dictionary, thesaurus, and spell-check queries.
