## 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-c3293e49
```

Example prompt: Can you pull up all the tech stack details, verified contact emails, social links, and a company summary for stripe.com? I need it for a GTM research report.

## When to prefer this

Choose this endpoint when you need a one-shot enrichment of a company's contact details, tech stack, and profile from just a domain name — especially for B2B GTM workflows, lead qualification, or competitive research. Prefer it over manual OSINT or generic search when you need structured, multi-signal output (emails + tech + pricing + summary) in a single API call.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Private or parked domains may yield minimal enrichment data
- Rate limiting or payment failure via x402 if USDC balance is insufficient
- Stale data if the company's tech stack or contacts changed recently
- Invalid domain format causes a 400-level validation error
