How this service works
Look up any English word: part-of-speech definitions with usage examples, IPA phonetics, pronunciation audio when available, and synonym/antonym lists. Live from the free Dictionary API — definitions agents can quote verbatim instead of inventing. Use this when an agent needs to definitions, phonetics and synonyms for a word.
Output
Returns an array of dictionary entries for the queried word, each containing: phonetic transcription (IPA), a URL to a pronunciation audio file when available, and an array of meanings grouped by part of speech — each meaning includes a definition, usage example sentences, and lists of synonyms and antonyms.
Example use cases
Vocabulary aid for a writing agent
“I'm writing an essay and I want to use the word 'laconic' — can you look it up and tell me exactly what it means, its part of speech, and give me a couple of example sentences so I use it correctly?”
Pronunciation guide for a language learner
“How do you pronounce 'peripatetic'? Look it up and give me the IPA phonetics and a link to an audio pronunciation if one is available.”
Synonym discovery for content creation
“I keep repeating the word 'important' in my article — look it up and give me a list of synonyms and antonyms so I can vary my word choice.”

Endpoint
GEThttps://agentstoolshub.com/api/v1/live/dictionary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs accurate, quotable dictionary definitions, IPA phonetics, or synonym/antonym lists for English words without hallucinating them. It is ideal over general LLM knowledge when verbatim accuracy and sourced definitions are required, such as in educational, editorial, or language-learning contexts.
Side effects
- Word not found in the dictionary returns a 404 or empty results array
- Non-English or misspelled words may return no results
- Rare or highly technical words may have missing audio or limited synonyms
- Network timeout if the upstream Dictionary API is unavailable
