"description": "Search live (or recently closed) tech and business job postings collected from employer ATS boards, career pages and partner feeds worldwide, with strong coverage of Europe, the Gulf, Central Asia and remote roles. Every row carries the employer, role family, seniority, work mode, locations (ISO country codes; remote roles also list hiring_countries, the countries they may hire in), the stated salary or a USD estimate with its method, the required technologies, when the posting was first seen and last verified on the employer's board, and a trust verdict (ok, stale, ghost). Use it to answer \"who is hiring X in Y\", to monitor a company's openings, or to pull a sample for analysis. Results are sorted newest first (or by pay with sort=salary) and paginated with an opaque cursor: pass next_cursor back to continue. Filters are combined with AND; unknown filter values return an empty list with a warning telling you what was accepted. Staffing agencies and intermediaries (job boards, talent marketplaces reposting other employers' roles) are excluded unless include_agencies=true. Each row links to its Alion page (url), which is also where a candidate applies. For counts, pay percentiles or who hires most, call market_stats instead of paging. Costs 1 unit per call.
