## 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-2b0c27e5
```

Example prompt: Can you enrich notion.so for me — I want their verified contact emails, tech stack, social links, and a company summary so I can prep for outreach?

## When to prefer this

Choose this endpoint when you need a comprehensive B2B company profile — including tech stack, verified contacts, and social links — from a single domain lookup. It is especially suited for GTM agents, sales automation pipelines, and competitive research workflows that need 40+ tech signals alongside contact data in one call, rather than stitching together multiple point solutions.

## Known failure modes

- Invalid or non-existent domain returns an error or empty result
- Domain with no detectable tech signals returns partial data
- Rate limiting or payment failure (HTTP 402) if payment is not properly attached
- Slow or unresponsive target domain may reduce signal quality
- Recently registered or parked domains may yield minimal enrichment data
