## 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-linkedin-company-lookup-275570ed -d '<json body>'
```

Example prompt: Use Deepline to look up decision-makers and find contact emails or phone numbers for the company at linkedin.com/company/stripe — their domain is stripe.com.

## When to prefer this

Use this endpoint when you need to enrich a specific company using their LinkedIn identity (URL or company ID), especially when you want decision-maker contacts, emails, and phones for B2B outreach or GTM research. Prefer this over generic enrichment APIs when LinkedIn is your primary identifier for the company.

## Known failure modes

- Company not found on LinkedIn — returns empty or null result
- Invalid LinkedIn URL or ID format — returns validation error
- Domain does not match any known company — falls back to name-based lookup
- Rate limit or payment failure — returns 402 or 429 error
- Insufficient data available for the company — partial result with missing fields
