USAJOBS API

Varies by plan (check documentation)

Overview

USAJOBS is the official US federal government job portal, and its API provides programmatic access to thousands of government job listings. Developers can search openings by keyword, location, agency, and pay grade to build specialized job search tools. Authentication uses an API key passed in the request header alongside your registered email address.

💡

Beginner Tip

USAJOBS requires both your API key and the email address used during registration as request headers—omitting either will result in a 401 error. Register at developer.usajobs.gov to get your credentials before making any calls.

Common Errors & Troubleshooting

401 Unauthorized Missing or mismatched API key or User-Agent email header.
Include both the Authorization-Key header with your API key and the User-Agent header with your registered email address.
400 Bad Request Invalid parameter names or values in the query string.
Refer to the USAJOBS API documentation for exact parameter names such as Keyword (capitalized), not keyword.
Empty SearchResult array No jobs match the combined filters such as a very specific agency plus rare keyword.
Remove some filters to broaden the search, or check that agency abbreviations match USAJOBS codes.
