## 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 serp-extract-agentdiet-dev-b2b-company-tech-stack-contact-lead-4619906c
```

Example prompt: Can you pull up the full company profile for stripe.com — I need their tech stack, verified contact emails, social links, and a quick company summary for our sales team?

## When to prefer this

Choose this endpoint when you need a one-shot firmographic and tech stack enrichment for a company domain without assembling multiple data sources. It is particularly well-suited for GTM agents doing account research, sales qualification workflows, or competitive intelligence where you need emails, social links, and tech signals together in a single call.

## Known failure modes

- Unknown or unresolvable domain returns empty or partial enrichment
- Private/stealth companies may yield minimal tech stack data
- Verified email coverage varies by company size and domain visibility
- Rate limiting or payment failure (x402) may block the request
- Malformed domain input returns a validation error
