## 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-65e4ec45
```

Example prompt: Can you pull up a full lead enrichment for stripe.com — I need their verified contact emails, social links, tech stack breakdown, and pricing tiers for our GTM research?

## When to prefer this

Choose this endpoint when you need a rich, multi-signal B2B company profile — combining contact discovery, tech stack intelligence, and pricing data in a single call — especially for GTM workflows, sales prospecting, or competitive research. Prefer it over point-solution email finders or tech stack checkers when you need all signals in one enriched payload per domain.

## Known failure modes

- Domain not found or invalid — returns empty or error response
- No tech stack signals detectable if site uses heavy obfuscation or is behind a proxy
- No verified emails found for privacy-protected or minimally-indexed domains
- Rate limiting or payment failure via x402 protocol if USDC balance is insufficient
- Stale data if the target company recently changed their stack or contact info
