Example Response

json

{
  "type": "spellcheck",

  },

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
