## 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 onchain-risk-agentdiet-dev-b2b-company-tech-stack-contact-lead-48fc9255
```

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

## When to prefer this

Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup — specifically when you want tech stack signals, verified emails, and GTM-ready lead data in one call. Prefer this over generic web scrapers when you need structured, normalized output across 40+ technology categories without building your own extraction pipeline.

## Known failure modes

- Domain not found or unreachable — returns empty or partial data
- Invalid domain format — may return error or no results
- Private/parked domains with no public signals — limited enrichment output
- Rate limiting or payment failure via x402 — HTTP 402 response
- Stale cached data for recently changed company tech stacks
