## 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-b3864863
```

Example prompt: Can you look up stripe.com and give me their tech stack, verified contact emails, social links, and pricing tier info so I can prep for an outbound sales call?

## When to prefer this

Choose this endpoint when you need a single-call, multi-signal enrichment of a B2B company domain — combining tech stack detection, contact discovery, social links, and pricing intelligence in one shot. Prefer it over generic web scrapers when you want structured, agent-ready output without building your own extraction pipeline, and especially when GTM, sales prospecting, or competitive research is the goal.

## Known failure modes

- Domain not found or unreachable — returns empty or partial data
- Invalid domain format — may return an error or null result
- Private/parked domains with minimal web presence may yield sparse tech stack data
- Rate limiting or payment failure via x402 may block the request
- Recently launched companies may have incomplete enrichment data
