## 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-29cde164
```

Example prompt: Can you pull up the full company profile for linear.app — I want their tech stack, any verified contact emails, social links, and a quick summary of what they do and how they price?

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup — especially when you need tech stack signals, verified contact emails, and company metadata together in one call. Prefer this over generic web scraping when structured, normalized GTM data is needed for sales prospecting or research workflows.

## Known failure modes

- Unknown or unresolvable domain returns empty or partial data
- Private/offline domains may yield no tech stack signals
- Emails may not be found for domains with heavy privacy protection
- Rate limiting or payment failure via x402 may block the request
- Malformed domain input returns a validation error
