## 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 email-verify-agentdiet-dev-b2b-company-tech-stack-contact-lead-2750320b
```

Example prompt: Can you pull up the full lead enrichment for notion.so — I need their verified contact emails, what tech stack they're running, their pricing tiers, and any social links you can find?

## When to prefer this

Choose this endpoint when you need comprehensive B2B lead enrichment from a single domain input — especially when you need a combined view of tech stack, contacts, and company profile in one call rather than stitching together multiple point solutions. Ideal for GTM agents, sales automation pipelines, and competitive research workflows where speed and breadth of signal per domain matter.

## Known failure modes

- Invalid or unresolvable domain returns an error or empty result
- Domain with no detectable tech stack may return sparse signals
- Private or stealth-mode companies may yield minimal contact data
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient
- Typo in domain input leads to enrichment of wrong company
