Search current US federal job postings via the USAJobs API. Filter by keyword, positionTitle, locationName ("Washington, DC" or city/zip), remote (telework-eligible), pay grade range (e.g. payGradeLow=GS09 + payGradeHigh=GS13), jobCategoryCode (occupational series, e.g. 2210 for IT), organization (agency sub-element code, e.g. TR40 for IRS), whoMayApply (all/public/status). Returns per-posting: control number, position ID, title, USAJobs URL + apply URL, organization + department, locations, schedule, offering type, pay scales (min/max + interval), publication start + application close, qualification summary, job category + grade. Use sortField + sortDirection to sort. Pagination via resultsPerPage + page.
/api/job/federal-searchPAYMENT-SIGNATURE.The federal search API is a pay-per-call job endpoint built for AI agents and autonomous software. Search current US federal job postings via the USAJobs API.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in federal search data source for an agent tool-use loop, an MCP host, or a backend that needs job data on demand without onboarding to yet another vendor portal.
