## 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 domain-osint-agentdiet-dev-b2b-company-tech-stack-contact-lead-2a939b34
```

Example prompt: Can you look up stripe.com and tell me what tech stack they're running, pull any verified contact emails or social links you find, and give me a summary of their pricing tiers?

## When to prefer this

Choose this endpoint when you need comprehensive B2B company enrichment from a single domain input — especially when you want tech stack detection, verified emails, and social links together in one call. Prefer this over generic web scrapers when the use case is GTM research, lead qualification, or competitive intelligence and you need structured, multi-signal output rather than raw HTML.

## Known failure modes

- Domain not found or does not resolve — empty or partial results returned
- Private or newly registered domains may yield minimal tech stack signals
- Rate limiting or payment failure via x402 may result in 402 or 429 errors
- Obfuscated or CDN-proxied sites may hide underlying tech stack signals
- Invalid domain format input returns a validation error
