People Data Labs provides B2B data products for building data-driven products and enriching person and company records. Its APIs can look up person profiles from details such as a name, location, email, phone, education, work history, or social profile; requests need sufficient information to identify a match. The company dataset describes more than 23.8 million global companies, with fields such as name, domain, industry, location, LinkedIn URL, employee count, and founding year. The listed contact database size is 3 billion, and the product includes direct-dial and intent data. API offerings cover person and company enrichment, search, IP enrichment, and person identification. The free plan is free for up to 100 credits per month, but contact data values are obscured. Pro starts at $98 a month, with 350 credits per month as the starting level and contact data included. Enrichment requests typically use one credit per successful request; Search uses one per returned profile.
