APIs for Lead Generation & Enrichment

Q: How do these APIs help with lead generation?

They cover the full path from discovery to enrichment: find businesses by category and location with Local Business Data and pull rich firmographics on each one (categories, ratings, reviews, hours, website, and 30+ data points), get contact details from a domain with Website Contacts Scraper and Email Search, and resolve social profiles with Social Links Search.

Q: Which API turns a website domain into contact details?

Website Contacts Scraper extracts emails, phone numbers, and social URLs from a website domain, while Email Search finds emails associated with a domain across the public web. Many teams use both together for fuller coverage.

Q: Can I build targeted prospect lists by industry or location?

Yes. Local Business Data lets you search businesses by category and geographic area, returning details and contact points you can then enrich, which is well suited to local and regional B2B prospecting.

Q: Is there a free tier?

Yes. You can start enriching leads on a free tier and scale up with predictable, usage-based pricing as your pipeline grows.

Find and enrich B2B leads at scale. Turn a domain, business name, or location into rich company data, emails, phone numbers, and social profiles ready for your CRM.
