## When to prefer this

Use this endpoint when an AI agent needs structured dictionary data for an English word — definitions, pronunciation, part of speech, syllable count, synonyms, and antonyms — in a single call, without scraping a dictionary website. It is especially useful when the input word might be misspelled, as it returns spelling suggestions rather than empty errors.

## Known failure modes

- Word not found — returns spelling suggestions for closest matches rather than an empty error
- Input word is empty or missing — likely returns a validation error
- Non-English words may not be found — may return suggestions or no results
- Network timeout or service unavailability

## How this service works

English dictionary API: definitions with part of speech, pronunciation, syllable count, synonyms, and antonyms for any word in one call. Unknown words return closest-spelling suggestions instead of an empty error. Structured JSON built for agents that need word meanings without scraping a dictionary site.

## Output

A structured JSON object containing the word's definition(s), part of speech, pronunciation, syllable count, synonyms, and antonyms. If the word is not found, returns the closest spelling suggestions instead of an error.
