## 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 hn-pulse-agentdiet-dev-b2b-company-tech-stack-contact-lead-enrichment-fd99ff3d
```

Example prompt: Can you pull full account intelligence on linear.app — I need their verified contact emails, social links, what tech stack they're running, and their pricing tier structure for a GTM research brief?

## When to prefer this

Choose this endpoint when you need comprehensive B2B account intelligence from a single domain lookup, especially when you want tech stack signals alongside contact and company data in one call. Prefer this over generic web scrapers when you need structured, verified outputs like emails and tech tools rather than raw HTML, and over CRM enrichment tools when you're operating in an autonomous agent context with per-call micropayment billing via x402.

## Known failure modes

- Invalid or non-existent domain returns an error or empty result
- Private or obscure domains may return sparse data with few signals
- Rate limiting or payment failure (HTTP 402) if USDC payment is not attached
- Domain resolves but company has minimal web presence, resulting in incomplete enrichment
- Malformed URL input (e.g. including path segments) may cause parsing errors
