## 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 x402broker-com-b2b-company-tech-stack-contact-lead-enrichment-95b5f0e0
```

Example prompt: Can you pull up the full company profile for stripe.com — I need their verified contact emails, social links, what tech stack they're running, and their pricing tier info for a GTM research report?

## When to prefer this

Choose this endpoint when you need a comprehensive single-call B2B company enrichment covering contacts, tech stack, and company metadata together. Prefer it over point-solution tools when GTM agents need verified emails alongside technology signals and pricing context in one payload, especially when working with SaaS or tech company domains.

## Known failure modes

- Domain not found or does not resolve to a real company website
- No tech stack signals detected for minimal/static websites
- Email verification may return empty if no public emails are discoverable
- Invalid domain format causes request rejection
- Rate limiting or payment failure via x402 micropayment protocol
