## 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-f6d7790e
```

Example prompt: Can you pull up the full company profile for notion.so — I need their verified contact emails, social links, tech stack breakdown, and pricing tier info before my sales call.

## When to prefer this

Choose this endpoint when you need comprehensive B2B lead enrichment from a single domain input — covering contacts, social presence, tech stack, and company context in one call. Prefer it over generic web scraping when you want structured, pre-extracted signals ready for GTM workflows or CRM population, especially when combined with email verification or domain OSINT needs within the same agent suite.

## Known failure modes

- Domain not found or unresolvable — returns empty or null results
- Private or parked domains may yield minimal tech stack data
- Unverified or outdated email addresses if company DNS records have changed
- Rate limiting or payment failure via x402 if USDC balance is insufficient
- Malformed domain input (e.g. including protocol or path when bare domain expected) may cause a lookup error
