## 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 defi-yield-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-2d19fbc3
```

Example prompt: Can you pull up the full company enrichment for hubspot.com — I need their verified contact emails, social links, and what tech stack they're running, especially any CRM, analytics, or marketing tools?

## When to prefer this

Choose this endpoint when you need comprehensive B2B company enrichment from a single domain lookup — especially when you want tech stack intelligence alongside contact data and company summary in one call. Prefer this over generic WHOIS or contact-finder tools when GTM context (pricing tiers, tech signals, social links) is needed together.

## Known failure modes

- Domain not found or invalid — returns empty or error response
- Domain resolves but company has minimal web presence — sparse results
- Rate limiting or payment required (HTTP 402) if credits are exhausted
- Incorrect domain format passed (e.g. full URL with path instead of bare domain)
- Tech stack signals may be incomplete for very small or obscure companies
