## 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 defi-yield-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-cce0015f
```

Example prompt: Can you enrich the company profile for notion.so — I need their verified contact emails, social links, what tech stack they're running, and their pricing tier structure for a GTM research report?

## When to prefer this

Choose this endpoint when you need a fast, single-call enrichment of a B2B company domain covering tech stack, contacts, and firmographics simultaneously — especially useful for GTM automation, lead scoring, or pre-call research workflows where you want 40+ tech signals alongside verified emails in one response rather than stitching together multiple data sources.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Private or newly registered domains may have sparse tech stack data
- No verified emails found if domain uses privacy protection or has no public contacts
- Rate limiting or payment required (HTTP 402) if x402 micropayment not provided
- Malformed domain input returns validation error

## Output
