Careerjet API vs USAJOBS API for AI agents
Careerjet API is a job search API for Careerjet publishers who show Careerjet's job listings on their own sites. USAJOBS API is the official REST API for searching public U.S. federal government job announcements on USAJOBS.
The short answer
- Careerjet API: Publishers who want to monetize traffic by showing Careerjet job listings to their own human visitors.
- USAJOBS API: Authoritative, reusable data on U.S. federal government job openings.
Side by side
| Careerjet API | USAJOBS API | |
|---|---|---|
| Searches | Careerjet's aggregated job listings, selected by a locale_code (language plus country, default en_GB). | Public job announcements posted on USAJOBS (status/internal jobs need extra steps); a single employer-side source, not an aggregator. |
| Returns | Jobs with title, company, date, description excerpt, locations, salary (currency, min, max, type) and url; plus type, hits, pages and response_time. | JSON SearchResult items with PositionTitle, PositionURI, ApplyURI, OrganizationName, PositionLocation (with lat/long) and PositionRemuneration. |
| Before the first call | A Careerjet Publisher account and one API key per publisher website (Basic auth); every call must send the end user's IP address and user agent. | An API key requested through an application form (name, email, phone, organization, intended use); calls send Host, User-Agent (your email) and Authorization-Key headers. |
| Acting on a result | The url field example is a tracking link (https://jobviewtrack.com/v2/...), not a direct employer link. | PositionURI/ApplyURI point to the announcement on usajobs.gov. |
| Limits on keeping or showing results | Not stated on its pages | Public Data may be copied, stored, republished and used commercially; attribution to USAJOBS is encouraged, not required; don't present modified data as official. Max 10,000 rows per query, 500 per page. |
| Coverage | Not stated on its pages | United States federal government jobs (in the U.S. and abroad). |
| MCP server | No official server listed | No official server listed |
