## 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 preflight-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-2cecfcf7
```

Example prompt: Can you enrich stripe.com for me — I need their verified contact emails, social links, tech stack details, and pricing tier info for our GTM research?

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup — especially when you want tech stack signals alongside contact/lead data in one call. Prefer this over generic WHOIS or LinkedIn scrapers when you need actionable GTM data including emails, pricing, and social links simultaneously, and when you need MCP/x402-compatible payment for agent-native workflows.

## Known failure modes

- Domain not found or invalid — returns empty or error response
- Private or parked domains may yield sparse data
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient
- Unresolvable domains or typos return no enrichment data
- Recently created domains may lack sufficient signals for enrichment
