## 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-907c2d75
```

Example prompt: Can you pull up the full company profile for stripe.com — I want their tech stack, any verified contact emails, social links, and pricing tier info so I can prep for an outreach call.

## When to prefer this

Choose this endpoint when you need a single-call enrichment of a B2B company domain that combines firmographics, tech stack detection, and contact data in one response. It is particularly well-suited for GTM agents, sales automation pipelines, and research agents that need to qualify leads without stitching together multiple specialized APIs. Prefer it over generic web scrapers when you need structured, signal-rich company intelligence including 40+ tech stack categories.

## Known failure modes

- Unknown or unresolvable domain returns empty or minimal results
- Private/parked domains with no detectable web presence may yield no tech signals
- Rate limiting or payment failure (HTTP 402) if x402 USDC micropayment is not properly handled
- Malformed domain input (e.g. missing TLD) may cause a validation error
- Some fields (e.g. verified emails) may be absent for companies with strong privacy posture
