## 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 suverse-dictionary-api-f8af75bd -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need free, keyless English dictionary data including definitions, phonetics, parts of speech, and synonyms for AI agents in language, education, or writing contexts. Prefer this over paid lexical APIs when no API key management is desired and the use case is standard English word lookup.

## Known failure modes

- Word not found in the dictionary — returns a 404 or empty result for obscure, misspelled, or non-English words
- Network or proxy timeout on the upstream Free Dictionary API
- Malformed request body missing required 'input' field returns a validation error
- Proper nouns, abbreviations, or slang terms may return no results
