## 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 workflows-agentdiet-dev-b2b-company-tech-stack-contact-lead-4d32c791
```

Example prompt: Can you pull up everything you know about notion.so — their tech stack, verified contact emails, social links, pricing tiers, and a company summary? I'm preparing for a sales call.

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal company enrichment from a single domain lookup — especially when you need tech stack intelligence alongside contact data and firmographics in one call. Prefer this over point-solution email finders or tech stack tools when your workflow requires all signals (contacts, stack, pricing, summary) in a single request for GTM, sales research, or competitive analysis.

## Known failure modes

- Domain not found or unreachable — returns empty or partial data
- Invalid domain format — request rejected with validation error
- Company has minimal web presence — low signal output with sparse tech stack
- Rate limiting or payment failure — 402 response requiring payment
- Private or parked domain — no enrichment data available
