## 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 alpha-stream-agentdiet-dev-b2b-company-tech-stack-contact-lead-981edcb4
```

Example prompt: Can you enrich stripe.com for me — I need their verified contact emails, social links, and what tech stack they're running, plus any pricing tier info you can find?

## When to prefer this

Use this endpoint when you need a single-call enrichment of a B2B company domain that combines contact leads, tech stack detection, social links, and company context in one response. Prefer it over point solutions (email-only finders, tech stack detectors) when your workflow needs multiple signals simultaneously for GTM, lead qualification, or competitive research.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Private or very small company with minimal web presence — limited or missing tech stack/email data
- Invalid domain format — returns validation error
- Rate limiting or payment failure via x402 — returns 402 or 429 status
- Domain resolves but company data is stale or sparse
