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.
Example use cases
Sales outreach contact discovery
“I'm trying to reach someone at notion.so — can you find their verified work emails and tell me what email provider they use?”
Email deliverability pre-check
“Before I send a cold email campaign to people at stripe.com, can you check whether stripe.com has a catch-all policy and verify any real contact emails you can find?”
Company enrichment for CRM
“I need to enrich my CRM record for hubspot.com — can you pull their verified emails, email provider, DMARC policy, and any other company details like their tech stack?”
Technical details
Endpoint
POSThttps://mailferret.appin60.com/company?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
