## 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 email-verify-agentdiet-dev-b2b-company-tech-stack-contact-lead-39d2c00c
```

Example prompt: Can you pull up the full company profile for salesforce.com — I need their verified contact emails, social links, tech stack breakdown, and pricing tier info for my sales research?

## When to prefer this

Choose this endpoint when you need a broad, multi-signal company enrichment in a single call — especially when you want tech stack intelligence combined with contact data and firmographics. Prefer this over single-purpose email finders or standalone Wappalyzer-style tech detectors when you need all signals together for GTM, sales outreach, or competitive research workflows.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Domain is too new or has minimal web presence — sparse enrichment results
- Rate limiting or payment failure via x402 — HTTP 402 response
- Invalid domain format supplied — validation error
- Company has no detectable tech stack (e.g. fully server-rendered with no JS signals)
