About Oxford

The Oxford Dictionaries API provides access to dictionary, translation, and lexical data across multiple languages through a single API. The Dictionary API covers definitions, pronunciations, example sentences, synonyms, and structured dictionary data, including child-focused datasets for education, literacy, and classroom use. The Translations API returns word-level translations across supported language pairs with lexical metadata, and the Lexical Data API exposes structured metadata such as inflections, domains, registers, and regional variation.

The service targets developers building games, learning applications, bots and AI systems, and research tools that require trusted dictionary and lexical content. It is used by companies for word-lookup features in games, structured language data for AI and bots, audio/examples/synonyms for learning applications, and deep lexical content for academic research.

Enterprise licenses are for commercial use only and start from an annual fee of £5,000 per language. A free trial is available for evaluating the API before committing to a paid plan.
