About 1Lookup

1Lookup is a data verification and enrichment platform that gives businesses access to multiple data tools through one API, one API key, and a universal credit system. It provides 47 live API endpoints covering email, phone, IP, company and B2B data, web and SEO intelligence, social data, business lookups, monitoring, and more.

Users can verify email addresses and phone numbers, check phone carriers and spam risk, enrich contact records, find prospects and business contacts, research companies, analyze domains, check backlinks and keywords, and access other data intelligence tools. 1Lookup also supports bulk processing, allowing users to process large datasets through its API.

The platform offers integrations with tools such as n8n, Make, and Zapier, as well as MCP support for AI workflows. It is designed for businesses and developers that need to verify, enrich, and research data without managing multiple data providers.
