How this service works
Alion is built to get you hired: 1,808,198 live roles read from employer boards and re-verified daily, your fit on every job, a resume rewritten for each application, direct apply. Free for developers.
Output
A paginated list of companies matching the search criteria, each including company ID, name, domain, industry, number of open jobs, size band, headquarters country, founding year, and date of last job posting. Also returns a next_cursor for pagination, a has_more flag, total returned count, any warnings, and a summary of filters applied.
Example use cases
Finding AI startups hiring engineers
“Can you search Alion for AI-focused startups in the US that are currently hiring, sort them by number of open jobs, and give me the top 10?”
Identifying recently funded companies recruiting
“Look up companies on Alion that have raised funding recently and are in the series B or later stage, filter to those actively hiring, and sort by most recent funding.”
Discovering large enterprise tech employers
“Search Alion for large technology companies with over 500 open positions right now, sorted by recent hiring activity, and show me their domains and headquarters countries.”
Technical details
Endpoint
GEThttps://alion.io/mcp/rest/search_companies?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or filter companies (not individual job listings) by characteristics like industry, country, hiring activity level, AI focus, funding stage, or investor. Prefer this over job-search endpoints when the goal is company intelligence — understanding which employers are actively hiring and fit certain organizational criteria — rather than finding specific open roles.
Side effects
- Invalid enum value for sort, ai_level, hiring_level, or detail fields returns a validation error
- limit exceeding 50 returns an error
- Malformed cursor string causes pagination to fail
- No companies match the filter combination, returning an empty items array
- Rate limiting or payment failure (402) if the x402 payment is not properly handled
