## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability alion-company-search-d074b1f7
```

Example prompt: Search Alion for fintech companies in the UK that are actively hiring, sort by recent hiring activity, and show me the top 20 results with their open job counts.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
