## 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-person-lookup-from-email-c924de9b -d '<json body>'
```

Example prompt: Using Deepline's GTM API, find the decision-makers and their contact details for the company at stripe.com — I want to know who to reach out to there.

## When to prefer this

Use this endpoint when you have a company domain, LinkedIn company page, or company name and need to discover decision-makers or enrich contact data for B2B outreach or GTM research. Prefer this over generic enrichment APIs when you specifically need person-level data from company-level inputs.

## Known failure modes

- Company domain not found or unrecognized — returns empty or null result
- LinkedIn URL malformed or company page not indexed — lookup fails
- Company name too ambiguous — returns incorrect or no match
- Rate limiting or payment failure — HTTP 402 or 429 response
- Insufficient data coverage for niche or small companies
