How this service works
Grammar & Spelling Check (30+ languages). Grammar, spelling and style check in 30+ languages (auto-detected): each issue with message, category, position and suggested replacements, plus a corrected version of the text. Powered by LanguageTool.
Output
Returns a JSON object with: 'issues' (integer count of detected problems), 'matches' (array of objects describing each error with position, message, and suggested replacements), and 'corrected_text' (the input text with corrections applied). Each match object typically includes offset, length, error message, and replacement suggestions.

Technical details
Endpoint
GEThttps://saylorinnovations.com/api/grammar/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, fast grammar and spelling validation for short to medium text snippets (up to 3000 chars) in any of 30+ supported languages, especially within automated pipelines that need pay-per-call pricing without a subscription. It's ideal for agent workflows that validate user input, proofread generated content, or enforce writing quality at scale.
Side effects
- Text exceeds 3000 character limit — request rejected or truncated
- Empty or missing 'text' query parameter — may return zero issues or error
- Unsupported language or ambiguous language detection — reduced accuracy
- Network timeout for very complex texts
- Non-textual input (code, binary) may produce irrelevant matches
