If you are wanting to use auto correction, then you will need to use our higher accuracy API - GrammarBot Neural. It can be found here:
https://rapidapi.com/grammarbot/api/grammarbot-neural/

With GrammarBot Neural, if you include the optional parameter “correction” and give it a value of “xml”, then the API response will include a “correction_xml” field. This can be embedded directly into an HTML document and styled with CSS. I hope this helps, but let me know if you have more questions. Here are some links with additional information:
