## 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-baa0f4a3
```

Example prompt: Can you pull up the full company profile for notion.so — I need their verified contact emails, tech stack breakdown, pricing tiers, and social links for our sales team?

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup, especially when you require a combination of contact emails, tech stack signals, and company context in one call. Prefer this over point-solution email finders or tech-stack-only tools when your workflow needs all these signals together for GTM, sales prospecting, or competitive research.

## Known failure modes

- Domain not found or unresolvable — returns empty or null fields
- Private/parked domain with no crawlable signals — minimal enrichment data returned
- Rate limiting or payment failure via x402 protocol — HTTP 402 response
- Malformed domain input — validation error returned
- Recently launched domain with insufficient data — partial results
