## 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 whale-momentum-agentdiet-dev-b2b-company-tech-stack-contact-lead-37063f08
```

Example prompt: Can you pull up the full company profile for stripe.com — I want their verified contact emails, social links, what tech stack they're running, and a quick summary of their pricing tiers?

## When to prefer this

Use this endpoint when you need a fast, broad firmographic snapshot of a B2B company from just their domain — especially when you want a bundle of verified contacts, social links, tech stack signals, and pricing info in a single call rather than stitching together multiple point solutions. Prefer this for GTM agents, sales enrichment workflows, and competitive research pipelines that operate on company domains.

## Known failure modes

- Invalid or unresolvable domain returns an error or empty result
- Private/obscure domains with no public footprint may return sparse data
- Rate limiting or payment failure (HTTP 402) if USDC payment is not properly attached
- Stale data if the company recently changed their tech stack or contacts
- Malformed domain input (e.g. including path or query string) may fail validation
