## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aisa-mpp-data-apis-brave-spell-check-search-d6d1d958
```

Example prompt: Can you spell-check the phrase 'recieve recomendations for resturants' in English for a US audience?

## When to prefer this

Use this endpoint when you need lightweight, fast spell-check corrections for a query string before passing it to a search engine or displaying suggestions to users. It is ideal for pre-processing user input to normalize typos, especially when multilingual or country-specific correction hints are needed. Prefer this over general NLP spell-checkers when Brave Search's index-aware correction logic is desirable.

## Known failure modes

- Empty query string returns validation error (q is required and must be at least 1 character)
- Query exceeding 400 characters or 50 words returns an error
- Unsupported language or country code results in a validation error
- Network or upstream Brave API failure returns a 5xx error
- No spelling corrections found returns an empty results array (not an error)
