## 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-55e8ef54
```

Example prompt: Pull up the full company profile for notion.so — I want their tech stack, any verified contact emails, social links, and pricing tier info for our outreach list.

## When to prefer this

Choose this endpoint when you need comprehensive B2B company enrichment from a single domain input, including tech stack intelligence, verified contact emails, and social links in one call. It is especially suited for GTM workflows, sales prospecting pipelines, and competitive research agents that need 40+ tech signals alongside contact and pricing data. Prefer this over generic WHOIS or DNS tools when you need human-usable lead data rather than just infrastructure metadata.

## Known failure modes

- Invalid or malformed domain input — returns 400-level error
- Company has minimal web presence — tech stack and contact data may be sparse
- Rate limiting or payment failure via x402 — returns 402 Payment Required
