## 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-security-agentdiet-dev-b2b-company-tech-stack-contact-lead-4637379f
```

Example prompt: Can you pull up the full tech stack, verified contact emails, and company summary for notion.so — I want to know what tools they're running and find leads for outreach.

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup — covering tech stack, contacts, and company context in one call. Prefer it over generic web scrapers when you want structured, pre-parsed GTM signals (emails, social links, pricing tier) without building your own extraction pipeline. Best for sales prospecting, competitive research, and lead enrichment workflows where per-domain cost is acceptable.

## Known failure modes

- Domain not found or unresolvable — empty or null result object
- Invalid domain format — request rejected at validation
- Private or parked domain with no detectable signals — sparse output
- Rate limit or payment failure (HTTP 402) — no enrichment returned
- Stale data for low-traffic domains — signals may be outdated
