## 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-9ee04e7f
```

Example prompt: Can you pull up the full company profile for stripe.com — I need their verified contact emails, social links, tech stack breakdown, and any pricing tiers you can find so I can prep for an outreach call.

## When to prefer this

Choose this endpoint when you need a broad, multi-signal firmographic profile of a company from just its domain — especially when you need tech stack intelligence, verified contact emails, and social links together in a single call. Ideal for GTM agents automating outreach personalization, sales intelligence pipelines, or competitive research workflows. Prefer this over general web scraping when you want structured, pre-extracted B2B signals without building your own extraction logic.

## Known failure modes

- Domain not found or unreachable — returns empty or partial data
- Invalid domain format — returns validation error
- Private or newly registered domain with insufficient public signals — sparse results
- Rate limiting or payment failure via x402 — returns 402 or 429 status
- Domain resolves but company has minimal web presence — low-confidence enrichment
