Use Cases

• Pre-search query cleanup: Check spelling before deciding which search endpoint to call
• "Did you mean?" UI: Show users a corrected suggestion before running the search
• Batch query normalization: Clean up user inputs in bulk

Notes

• Built-in alternative: Web Search and LLM Context have spellcheck=true by default — use this standalone endpoint only when you need the correction before searching
• Context-aware: Corrections consider the full query context, not just individual words
