Contact details for a whole list, by API
This page looks up one website at a time. For a list of companies, the same extractor runs behind one API call: up to 10 domains per request, returning JSON with emails, phones and social links. Sites with nothing to return are not billed.

Frequently asked questions
Is this contact finder free?
Yes. No account and no card. Everyone shares a daily allowance (up to 15 free runs per network per day across our free tools, plus a fixed daily total), which keeps it free. A site you've looked up is cached for 24 hours.
Where does it find email addresses and phone numbers?
It reads the site's public pages: the homepage plus common contact, about, team and support pages (up to 6 pages for the free tool). Emails come from page text and mailto: links, phone numbers from text and tel: links. Social profiles come only from the site's structured data and its header, footer and navigation, so links to other companies in the body of a page are ignored.
Does it guess or verify emails?
No. It only returns addresses that are actually published on the site. It does not guess patterns like first.last@company.com, and it does not check whether a mailbox exists.
Why did it find nothing?
Some sites show contacts only inside contact forms, images or JavaScript widgets, put them behind a login, or block automated requests. An empty result is shown as such and is not an error.
Is it OK to email the addresses it finds?
Finding a public address is not permission to send marketing email. Business-to-business outreach is regulated differently in each country (GDPR and ePrivacy in Europe, CAN-SPAM in the US). Keep messages relevant, identify yourself and honour opt-outs.
How do I do this for hundreds of companies?
Use the Contact Details Extractor: the same engine takes lists of domains through the Siftwright API (/v1/contact-details) or as an Apify Actor at $2 per 1,000 websites, and sites with no result are free.
Contact details for every company on your list
Emails, phones and social links from company websites through one API key. Plans from $29/month; sites with no result never count.
