## 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 x402-audit-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-424240bc
```

Example prompt: Can you look up linear.app and pull together their tech stack, verified contact emails, social links, pricing tiers, and a company summary so I can prep for an outbound sales call?

## When to prefer this

Choose this endpoint when you need a comprehensive, all-in-one B2B company intelligence profile from a single domain lookup — especially when you want tech stack signals alongside contact data and pricing in one call. Prefer this over point-solution enrichment APIs when building GTM workflows, sales prospecting pipelines, or competitive research agents that need breadth of signals rather than depth in one category.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Private/parked domains may yield sparse results with few or no signals
- Rate limiting or payment failure via x402 protocol may block the request
- Newly registered domains may have insufficient data for enrichment
- Some tech stack signals may be stale if the company recently changed infrastructure
