## 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-d4aa3aa4
```

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 tiers for a sales prospecting brief.

## When to prefer this

Choose this endpoint when you need comprehensive B2B firmographic enrichment — tech stack, contacts, social profiles, and pricing — from a single domain lookup. Prefer it over generic web scrapers when you need structured, pre-parsed lead intelligence for GTM workflows, sales prospecting, or competitive research, especially when the input is just a domain name.

## Known failure modes

- Domain not found or unresolvable — returns empty or error response
- Private or parked domains may yield sparse or no tech stack data
- Emails may not be available for all companies, returning null or empty arrays
- Rate limiting or payment failure via x402 protocol may block the request
- Malformed domain input (missing TLD, spaces) returns validation error
