## 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-7dd8b9f2 -d '<json body>'
```

Example prompt: Can you pull up the full lead enrichment for stripe.com — I need their verified contact emails, social links, tech stack breakdown, and pricing tier info for our GTM research?

## When to prefer this

Choose this endpoint when you need comprehensive, multi-signal B2B company enrichment from a single domain input — particularly when you need tech stack detection alongside contact emails and social links in one call. Prefer over generic WHOIS or contact-scraping tools when GTM context (pricing tiers, tech signals, verified emails) is required together.

## Known failure modes

- Invalid or unresolvable domain returns an error or empty result
- Domain with heavy bot protection may yield partial tech stack data
- Newly registered or obscure domains may have minimal enrichment data
- Payment failure (HTTP 402) if x402 USDC balance is insufficient
- Rate limiting or timeout if the domain lookup takes too long
