This API is specific to Search.gov and exposes the type-ahead suggestions that can appear below your search box as searchers enter their search terms.

We have a script available that calls this API for you, which you can use as an alternative to using this API directly. Find it in Admin Center > YourSite > Activate > Code Snippets.

Getting Started

A given term/phrase must be searched 10 times in a 24 hour period to appear as a suggestion. Suggestions will drop from the list if they don’t maintain the 10 times per 24 hour period threshold.
