## 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 zinin-m2m-hub-domain-to-verified-work-email-ab941a74 -d '<json body>'
```

Example prompt: Can you find and verify the work email for King Lee at visionwide.co — I need a confirmed address I can use for outreach, with a confidence score?

## When to prefer this

Choose this endpoint when you need a verified, evidence-backed work email for a specific named person at a known company domain, and want confidence scoring and source evidence rather than a raw unverified guess. It is especially valuable for B2B sales outreach, CRM enrichment, or investor prospecting where email accuracy matters. Prefer this over bulk email guessing tools when you need per-person verification with audit trail, recommended action guidance, and retryability signals.

## Known failure modes

- Email not found (found: false) when person is not listed on any public company page
- MATCHER_WORK_LIMIT_EXCEEDED when CSS rules prevent email candidate evaluation, returning partial result with safeToAutomate: false
- Robots.txt disallowed pages blocking scraping of relevant team/contact pages
- Domain unreachable or pages returning non-200 status codes
- No unique evidence-backed person match found, returning null email per disclaimer policy
- Rate limiting or payment settlement failure at the x402 payment layer

## Output
