## 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 domain-osint-agentdiet-dev-b2b-company-tech-stack-contact-lead-43b94309
```

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

## When to prefer this

Choose this endpoint when you need comprehensive B2B company enrichment from a single domain lookup, including tech stack detection, contact discovery, and firmographic summary in one call. Ideal for GTM agents, sales automation pipelines, and competitive research workflows that require more than just basic WHOIS or LinkedIn data. Best when you need 40+ technology signals alongside verified contact information without stitching together multiple data sources.

## Known failure modes

- Domain not found or unresolvable — may return empty or partial data
- Private or parked domains with no detectable tech stack return minimal signals
- Rate limiting or payment failure (HTTP 402) if micropayment is not properly handled
- Malformed domain input may result in validation error
- Some email addresses may be unverifiable if domain has strict privacy protections
