## 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 x402broker-com-b2b-company-tech-stack-contact-lead-enrichment-api-60c7bf86
```

Example prompt: Can you pull the full company profile for stripe.com — I need their tech stack, any verified contact emails, social links, and a quick company summary for my outbound research?

## When to prefer this

Choose this endpoint when you need a one-call enrichment of a company domain that covers contact leads, tech stack fingerprinting, and firmographic summary simultaneously — especially useful for GTM agents, sales automation, and competitive research pipelines where breadth of signal per domain matters more than deep crawl of a single data dimension.

## Known failure modes

- Unknown or unresolvable domain returns empty or partial data
- Private or newly registered domains may yield minimal signals
- Rate limiting or payment failures return 402 or 429 status
- Malformed domain input returns a validation error
- Some tech stack signals may be stale if the company recently changed vendors
