## 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 shopify-spy-agentdiet-dev-b2b-company-tech-stack-contact-lead-4d3f480d
```

Example prompt: Can you pull up all the firmographic details for linear.app — I need their tech stack, any verified contact emails, social links, and a company summary so I can prep for outreach.

## When to prefer this

Choose this endpoint when you need a one-call enrichment of a B2B company domain that combines contact leads, tech stack intelligence, and firmographic summary — especially for GTM workflows, sales prospecting, or competitive research. Prefer it over generic WHOIS or DNS tools when you need actionable sales signals like verified emails and technology fingerprints alongside company context.

## Known failure modes

- Private/parked domains may return sparse or no tech stack data
- Newly registered domains may lack sufficient crawlable signals
- Rate limits or payment failures via x402 may block the request
