## 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 serp-extract-agentdiet-dev-b2b-company-tech-stack-contact-lead-7a0bcfb6 -d '<json body>'
```

Example prompt: Can you look up stripe.com and give me their verified contact emails, tech stack tools, pricing tiers, and a company summary so I can prep for an outreach campaign?

## 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 detection alongside contact leads and company summary in one call. Prefer this over generic WHOIS or LinkedIn scrapers when you want actionable GTM signals like verified emails, social links, and SaaS pricing tiers in a single enriched response.

## Known failure modes

- Domain not found or invalid returns empty or partial results
- Private or obscure domains may yield limited tech stack signals
- Email extraction may return zero results if no public emails are indexed
- Rate limiting or payment failure (HTTP 402) if payment is not properly attached
- Stale data if the company recently changed their tech stack
