## 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 preflight-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-22f466b7
```

Example prompt: Can you pull up the full company profile for linear.app — I need their verified contact emails, social links, tech stack signals, and pricing tier for our sales research?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal B2B account intelligence profile for a single domain — especially when you want tech stack data, verified contacts, and company metadata in one call. Prefer it over generic web scrapers when you need structured GTM-ready output with 40+ technology signals and contact leads rather than raw HTML or generic company descriptions.

## Known failure modes

- Domain not found or not enrichable — sparse or empty result object returned
- Invalid or malformed domain input — validation error
- Rate limiting or payment required (HTTP 402) if x402 micropayment not processed
- Domain resolves to a personal site or parked page — low-confidence or empty enrichment
- Tech stack signals unavailable for very new or obscure domains
