## 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 prompt-guard-agentdiet-dev-b2b-company-tech-stack-contact-lead-3ec8ccd0
```

Example prompt: Can you pull the full company profile for notion.so — I need their tech stack, any verified contact emails, social links, pricing tier info, and a company summary so I can prep for an outreach call?

## When to prefer this

Choose this endpoint when you need a fast, single-call B2B account enrichment that combines tech stack intelligence, contact discovery, and firmographic data in one response. Ideal for GTM agents, sales automation, and research workflows where breadth of signal (emails + social + tech + pricing + summary) matters more than deep CRM integration. Prefer this over point solutions (email-only or tech-stack-only tools) when you need all signals in one call.

## Known failure modes

- Domain not found or unresolvable — returns empty or partial data
- Invalid domain format — returns validation error
- Company has no detectable tech stack signals — returns sparse tech fields
- Rate limiting or payment failure via x402 — returns 402 or 429
- Private or newly registered domain with no crawlable data — returns minimal results
