## 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-8eb980dd
```

Example prompt: Can you pull up full firmographic details for notion.so — I need their tech stack, any verified contact emails, social links, and what pricing tiers they offer for our outbound GTM campaign?

## When to prefer this

Choose this endpoint when you need comprehensive B2B firmographic enrichment — including tech stack, contact emails, and social links — from a single domain lookup. Prefer it over generic web scrapers when you want structured, multi-signal output suitable for GTM workflows, lead enrichment pipelines, or competitive research without building custom extraction logic.

## Known failure modes

- Unknown or unresolvable domain returns empty or partial results
- Private/stealth companies with minimal web presence may yield few tech stack signals
- Rate limiting or payment failure (HTTP 402) if x402 payment is not properly handled
- Malformed domain input returns a validation error
- Recently rebranded or redirected domains may return stale data
