## 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 mailferret-company-email-lookup-12c586a3 -d '<json body>'
```

Example prompt: Can you find and verify the work email addresses for cal.com? I need their real contact emails with SMTP validation, not just guesses.

## When to prefer this

Choose this endpoint when you need live, SMTP-verified email addresses for a specific company domain rather than unverified guesses. It combines email discovery with company enrichment (logo, description, tech stack, DMARC policy) in a single call. Prefer it over static email databases when freshness and deliverability confidence matter. It requires no API key and charges only on successful results via x402 USDC micropayment, making it cost-efficient for spot lookups or agent-driven outreach workflows.

## Known failure modes

- Domain not found or invalid — returns error status
- No public emails discoverable for the domain
- SMTP check times out or is blocked by mail server
- Domain uses aggressive anti-scraping measures preventing lookup
- Catch-all domains may return misleading verification results
- Payment failure via x402 prevents the request from being processed

## How this service works

Company enrichment from a domain: company name, description, logo, social profiles (LinkedIn, X, GitHub...), schema.org organization data (founded, address), website tech (Next.js, Webflow, HubSpot, Stripe, PostHog...), email provider, catch-all, SaaS tools from SPF, DMARC and public email addresses. Built from the company's own website and DNS; no third-party data broker.

## Output

Returns a JSON object with the company's verified email addresses (including source URL and role flag), email provider name, catch-all status, DMARC policy, SPF-derived SaaS tools, company name, logo URL, description, website technologies used, social profiles, and overall status field indicating success or failure of the lookup.
