## 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-d43103c8
```

Example prompt: Can you pull full firmographic enrichment for linear.app — I need their verified contact emails, social profiles, tech stack signals, and pricing tier info for a GTM research brief.

## When to prefer this

Choose this endpoint when you need a broad, multi-signal company enrichment in a single call — covering contacts, tech stack, pricing, and firmographics simultaneously. Prefer it over single-purpose enrichment APIs when building GTM workflows, sales prospecting pipelines, or competitive research agents that need more than just contact info or just tech stack data.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Private or newly registered domains may yield sparse results
- Some tech stack signals may be stale if the company recently changed vendors
- Email verification may return unconfirmed addresses for heavily protected domains
- Malformed or non-domain URLs may cause a validation error
