Text Correction & Word Tools API

What it does

Text Correction & Word Tools API fixes spelling and transforms individual words. Send a passage of text or a single word as a query parameter and get back JSON with the corrected text, a list of synonyms, or the word's singular or plural form next to the original.

Correct Spelling takes text plus a language code (for example en) and returns corrected_text with misspellings fixed. List Word Synonyms takes a word and returns a synonyms array of strings. Singularize Word takes a word and returns the original and its singular form, and Pluralize Word does the reverse, returning the original and its plural form.

Text Correction & Word Tools API is a good fit when you need to clean up user-entered text, expand search queries with related words, or generate grammatically correct labels and messages ("1 item" vs "3 items") without maintaining your own word lists.
