## 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-english-dictionary-eb299b8e -d '<json body>'
```

Example prompt: Can you look up the word 'serendipity' and give me its definition, part of speech, how to pronounce it, syllable count, and a few synonyms and antonyms?

## When to prefer this

Use this endpoint when you need a structured, machine-readable English dictionary entry with consistent JSON output — ideal for vocabulary apps, crossword solvers, language-learning agents, or any workflow that needs definitions, pronunciation, syllable counts, and synonym/antonym data in a single call. Prefer this over a general web search when you need deterministic, parseable lexical data rather than unstructured prose.

## Known failure modes

- Word not found in dictionary — returns empty or error response
- Non-English word submitted — may return no results or partial data
- Misspelled word — may return no match or nearest entry depending on implementation
- Empty or missing 'word' field — likely returns a validation error

## How this service works

Machine-readable English dictionary entry by word: definitions across senses, part-of-speech tags, phonetic pronunciation, syllable count, and related synonyms/antonyms. Deterministic JSON shape for vocabulary apps, crossword helpers, and language-learning agents.

## Output

A deterministic JSON object containing the word's definitions across multiple senses, part-of-speech tags (e.g. noun, verb, adjective), phonetic pronunciation string, syllable count, and lists of related synonyms and antonyms.
