## 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 deepline-gtm-api-personal-email-discovery-b8339072 -d '<json body>'
```

Example prompt: Find personal email addresses for people at stripe.com — use their LinkedIn at linkedin.com/company/stripe as a fallback if needed.

## When to prefer this

Use this endpoint when you need personal (not generic role-based) email addresses for individuals at a specific company and can supply a company domain, LinkedIn company page, or company name. Prefer this for B2B sales prospecting, outbound GTM workflows, or decision-maker contact discovery where waterfall multi-source enrichment is needed.

## Known failure modes

- Company domain not found or unresolvable — returns empty or error response
- LinkedIn URL malformed or company not indexed — lookup fails
- No email data available for the given company — empty result returned
- Rate limit or payment failure — 402 or 429 response
- Invalid input schema — 400 bad request
