## 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 alpha-stream-agentdiet-dev-b2b-company-tech-stack-contact-lead-fe1547d1
```

Example prompt: Can you pull up the full company profile for stripe.com — I need their verified contact emails, social links, what tech stack they're running, and any pricing tier info you can find?

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence — combining contact discovery, tech stack profiling, and firmographic enrichment — from a single domain input. It is ideal for GTM agents, sales automation, and competitive research workflows where breadth of signal (emails + tech + pricing + social) matters more than deep specialization in any one data type.

## Known failure modes

- Invalid or unresolvable domain returns an error or empty result
- Private or very new domains may have limited tech stack data
- No verified emails found for some domains with strict privacy practices
- Rate limiting or payment failure may block the request
- Domain typos or malformed URLs result in failed lookups
