## What it does

The skill sends a query to the Brave Search Spellcheck API and returns the original text alongside correction suggestions. Suggestions use the context of the whole query, and the results can be empty. You can set a language and search country.

A Brave Search API key is required in the `X-Subscription-Token` header. Use this endpoint when you need a correction before searching; Web Search and LLM Context have spellcheck enabled by default. Without the key, the endpoint request will fail.

# Spellcheck

> **Requires API Key**: Get one at https://api.search.brave.com
>
> **Plan**: Included in the **Spellcheck** plan. See https://api-dashboard.search.brave.com/app/subscriptions/subscribe

## Quick Start (cURL)

```bash
curl -s "https://api.search.brave.com/res/v1/spellcheck/search" \
  -H "Accept: application/json" \
  -H "X-Subscription-Token: ${BRAVE_SEARCH_API_KEY}" \
  -G \
  --data-urlencode "q=artifical inteligence" \
  --data-urlencode "lang=en" \
  --data-urlencode "country=US"
```

## Endpoint

```http
GET https://api.search.brave.com/res/v1/spellcheck/search
```

**Authentication**: `X-Subscription-Token: <API_KEY>` header

## Parameters

| Parameter | Type | Required | Default | Description |
|--|--|--|--|--|
| `q` | string | **Yes** | — | Query to spell check (1-400 chars, max 50 words) |
| `lang` | string | No | `en` | Language preference (2+ char language code, e.g. `en`, `fr`, `de`, `pt-br`, `zh-hans`). 51 codes supported |
| `country` | string | No | `US` | Search country (2-letter country code or `ALL`) |

## Response Fields

| Field | Type | Description |
|--|--|--|
| `type` | string | Always `"spellcheck"` |
| `query.original` | string | The input query as submitted |
| `results` | array | Spell-corrected suggestions. May be empty when no correction is found |
| `results[].query` | string | A corrected version of the query |

## Example Response

```json
{
  "type": "spellcheck",
  "query": {
    "original": "artifical inteligence"
  },
  "results": [
    {
      "query": "artificial intelligence"
    }
  ]
}
```

## 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
