Resources For Developers

In line with the White House’s Digital Government Strategy, we’re making our code and data more open.

APIs For Customers

These APIs are available for use on official government websites only. You must be a customer. Sign in is required.

Search Results API — This API exposes all relevant results “modules” in a single JSON call, including: web results, best bets, health topics, job openings, recent tweets, recent news, recent videos, Federal Register documents, and related searches. Use it to pull search results from our service to display on your agency’s website or mobile applications.

Clicks API - This API is to use in parallel with the Search Results API. It allows sites that display results on their own websites to send click action data into our system for analysis.

Typeahead API - This API exposes the typeahead suggestions that often appear below your search box as searchers enter their search terms. We recommend, however, that instead of using this API you use our javascript snippet that will call the API for you.

i14y — This API is still available, but we strongly encourage the use of sitemap-based indexing instead. Read more about our indexing process here. The i14y API allows you to send content directly from your content management system (CMS) into for real-time indexing.

Punchcard — The repository of synonyms, protected words, stop words, and other vocabularies that we use to improve the precision, recall, and usability of search results.
