WordsAPI
An API for the English language providing definitions, related words, rhymes and more viaa
WordsAPI is a REST API that provides English language data for applications that need dictionary and thesaurus lookups. It returns definitions for English words along with synonyms, antonyms, similar words, hierarchical relationships (such as type-of and part-of), pronunciations, syllables, and frequency of usage information.
The API exposes these lookups through a simple RESTful interface, with a browser-based Try It tool for testing queries. Account billing and access are handled through RapidAPI, where a free Basic tier allows a limited number of daily requests and paid tiers (Pro, Ultra, Mega) raise the daily request allowance. Alternatively, the full dataset can be purchased as a JSON file for local hosting and unrestricted use, with a sample file available for evaluation; reselling the data or using it in a competing service is not permitted.
