Frequently asked questions
How can I filter jobs by a specific location and salary range?
Use the search_jobs tool. You can provide parameters like LocationName (e.g., 'Washington, DC') and RemunerationMinimumAmount to narrow down the results to your specific needs.
Where can I find the full description of duties for a job posting?
The get_announcement_text tool is designed specifically for this. By providing the announcement number, the agent will retrieve the full text for Summary, Duties, and Qualifications.
How do I know which codes to use for occupational series like IT or Engineering?
You can use the get_code_list tool with the endpoint 'occupationalseries'. This will return a list of all valid codes and their corresponding titles (e.g., 2210 for Information Technology).
