## 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 mcp-security-agentdiet-dev-b2b-company-tech-stack-contact-lead-de691cbb
```

Example prompt: Can you pull up the full company profile for notion.so — I need their tech stack, verified contact emails, social links, and pricing tier info for a sales outreach I'm putting together.

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup — especially when you need tech stack signals, verified contact emails, and firmographic summary in one call. Prefer this over generic web scraping when you need structured, sales-ready output for GTM, lead scoring, or competitive research workflows.

## Known failure modes

- Invalid or non-existent domain returns empty or error response
- Private/personal domains may return minimal firmographic data
- Rate limiting or payment failure via x402 protocol may block the request
- Newly registered domains may lack sufficient signals for enrichment
- Paywalled or obscured tech stacks may result in incomplete signal coverage
