## 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-company-enrichment-decision-maker-lookup-575df85c -d '<json body>'
```

Example prompt: Can you pull up the decision-makers and their emails or phone numbers for stripe.com using Deepline — I need contacts for a B2B outreach campaign.

## When to prefer this

Use this endpoint when you need to enrich a B2B prospect with verified contact details (emails, phones) and decision-maker information given a company domain, LinkedIn page, or company name. Prefer over generic search when you need structured sales intelligence with waterfall email discovery specifically for GTM workflows.

## Known failure modes

- Domain not found or unresolvable — returns empty or partial enrichment
- LinkedIn URL malformed or company not indexed — falls back to name-based lookup
- No contacts found for niche or small companies — returns empty contact arrays
- Payment failure via x402 — request not processed
- Rate limiting or server error — HTTP 5xx response
