## 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 mcp-compiler-agentdiet-dev-b2b-company-tech-stack-contact-lead-08df7792
```

Example prompt: Can you pull up the full company profile for linear.app — I need their verified contact emails, what tech stack they're running, their pricing tier, and any social links you can find?

## When to prefer this

Choose this endpoint when you need a single-call enrichment of a B2B company domain that combines contact data, tech stack detection, and firmographic summary together. Prefer it over generic web scrapers when you need structured, sales-ready intelligence (emails, social links, tech signals, pricing tier) without building your own scraping pipeline. Ideal for GTM agents, CRM enrichment workflows, and competitive research tasks where domain is the only known input.

## Known failure modes

- Domain not found or invalid — returns empty or partial data
- Private or unindexed domain with no detectable signals — minimal output
- Rate limiting or payment failure via x402 — 402 response requiring payment
- Newly registered domain with no crawlable data — sparse results
- Malformed domain input — validation error

## How this service works

## Output
