# Autocomplete

## Autocomplete API

The Autocomplete API returns suggestions for the autocompleter, as the user types the query in the search bar. It is suggested to wait at least 300ms between keystrokes before calling the API.

Autocomplete API can return lists of query suggestions, and products that match the query. Use appropriate `limit` values as per use case.
