## 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-email-from-linkedin-83a584bb -d '<json body>'
```

Example prompt: Using Deepline's waterfall email discovery, find email addresses for the company at linkedin.com/company/stripe or domain stripe.com — their company name is Stripe.

## When to prefer this

Use this endpoint when you need to discover email addresses for a specific company and have their LinkedIn company page URL or domain available. Prefer this over generic email guessing tools when LinkedIn data is the primary identifier for the target company.

## Known failure modes

- Company not found on LinkedIn — returns empty or null result
- Domain or LinkedIn URL not recognized — validation error
- No emails discoverable for company — empty results
- Rate limiting or payment failure — 402 or 429 error
- Invalid LinkedIn URL format — 400 bad request
