Correct Text Spelling API

What it does

Spellcheck Text detects misspelled words in short text and returns a corrected version. Send a text string and get back the original text, the corrected text, and a map of misspelled words to their replacements.

Use it when you need to clean user-entered content, normalise short messages before storing them, or add a quick spellcheck step to forms and chat workflows. The request body accepts a single text field, with input limited to 512 tokens.

The response includes original and corrected strings, plus a misspelled object for word-level fixes. That makes it easy to compare the source text with the corrected output or highlight the changes in your own interface.

Spellcheck Text is a good fit for editors, support tools, content moderation pipelines, and any application that needs lightweight text correction without building a full language model flow.
