## 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-a7a036a8
```

Example prompt: Can you look up linear.app and tell me what tech stack they're running, any verified contact emails you can find, their pricing tiers, and a quick company summary?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal company enrichment in a single call — combining tech stack detection, contact email extraction, social links, pricing, and a company overview from just a domain name. Prefer it over standalone email verifiers (which don't provide tech stack data) or generic web scrapers (which lack structured lead enrichment outputs). Ideal for GTM agents, sales automation, competitive research, and investor due diligence workflows where broad B2B intelligence is needed quickly.

## Known failure modes

- Domain not found or invalid — returns empty or error if the domain doesn't resolve
- No tech stack signals detected for domains with heavy obfuscation or minimal public web presence
- No emails found if the company doesn't publish contact info publicly
- Rate limiting or payment required (HTTP 402) if usage quota is exceeded
- Partial results if the company uses a heavily JavaScript-rendered or bot-protected site
