## 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-37d7048e -d '<json body>'
```

Example prompt: Can you pull up full company intelligence on stripe.com — I need their verified contact emails, social profiles, tech stack, and pricing tier info for our GTM research?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal enrichment of a B2B company in a single call — covering contact leads, tech stack, social links, and firmographics simultaneously. Prefer it over point-solution email finders or tech stack checkers when you need all signals together for GTM, sales prospecting, or competitive research at a low per-call cost.

## Known failure modes

- Domain not found or unresolvable — returns empty or partial data
- Invalid domain format — validation error
- Rate limit or payment failure via x402 — HTTP 402 or 429
- Private/internal domain with no public signals — minimal data returned
- Stale tech stack data if the company recently changed providers
