## 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 ats-jobs-api-email-check-d9edf0f8
```

Example prompt: Can you check if jane@example.com is a real, non-disposable email address and tell me whether it's a role account?

## When to prefer this

Choose this endpoint when you need lightweight, real-time email hygiene checks within a recruiting or job-application workflow — particularly when you want to detect disposable addresses and role accounts before initiating candidate outreach, and when you are already using the ATS Jobs API ecosystem for job data.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Ambiguous or unreachable mail server may yield an inconclusive verdict
- Disposable provider databases may lag behind newly created throwaway services
- Role-account detection relies on heuristics and may miss non-standard prefixes

## How this service works

Open job postings read first-hand from the applicant-tracking system behind a company's careers page: Greenhouse, Ashby, Lever or Workable. Includes a directory of 8532 company job boards, because none of the vendors publishes one. Salaries are parsed into numbers where the employer publishes them and refused where ambiguous. No personal data.

## Output

Returns a JSON object with the queried email address, a verdict string (e.g. 'mail_server_found'), a boolean indicating whether the address is disposable, and a boolean indicating whether it is a role account (e.g. info@, support@).
