## 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 prompt-guard-agentdiet-dev-b2b-company-tech-stack-contact-lead-2c665926
```

Example prompt: Can you pull up the full company profile for linear.app — I need their verified contact emails, social links, and what tech stack they're running, including any pricing tier signals?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call company enrichment covering tech stack, contacts, and social links for a given domain. Prefer it over generic WHOIS or social scrapers when you need GTM-ready signals like pricing tiers and verified emails in one response. Best for sales research, lead enrichment pipelines, and competitive intelligence workflows.

## Known failure modes

- Domain not found or unresolvable returns empty or error response
- Private/obscure domains may yield sparse tech stack data
- Email verification may return no results for domains with strong privacy protections
- Invalid domain format returns a validation error
- Rate limits or payment failures (x402) result in 402 or 429 responses
