## 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 signal-lists-api-hiring-ai-ml-companies-x402-usdc-on-base-f0027ca4
```

Example prompt: Pull me today's list of companies that are actively hiring in AI and machine learning — I want the company names and their domains in JSON so I can import them into our CRM as fresh leads.

## When to prefer this

Choose this endpoint when you need a ready-made, daily-refreshed list of companies actively hiring in AI/ML without having to scrape or parse job boards yourself. It is ideal for B2B sales prospecting, competitive intelligence, and market research workflows where company-level signals (not individual job postings) are the unit of interest. Prefer this over raw job-board scrapers when you want structured, deduplicated company+domain pairs with source attribution, paid per-call via x402/USDC on Base.

## Known failure modes

- Payment failure: x402 USDC payment on Base not confirmed, request rejected with 402 status
- Invalid format parameter: value other than 'json' or 'csv' returns a validation error
- Data staleness: if upstream ATS or EDGAR sources are delayed, list may reflect previous day's snapshot
- Empty result set: no companies currently match the hiring-ai-ml signal criteria, returns count of 0 and empty rows array
- Network timeout: Cloudflare Pages edge function may time out under load

## How this service works

Company-level B2B lead signals from public ATS job boards and SEC EDGAR, refreshed daily.

## Output

A JSON (or CSV) payload containing the list name ('hiring-ai-ml'), a count of matching companies, and an array of company-level rows each with at minimum the company name, domain, and a source URL pointing to the original ATS posting or SEC EDGAR entry. Also includes a 'generated' timestamp indicating data freshness.
