People Data Labs
Person and company data APIs for enrichment, search and IP-to-company lookups.
Updated Sep 27, 2026
Overview
People Data Labs (PDL) is a B2B data provider. Its REST API matches people against a dataset of nearly three billion profiles and companies against its company records, searches both with Elasticsearch or SQL queries, and resolves IP addresses to the companies behind them. Official SDKs cover Python, JavaScript, Ruby, Go and Rust.
The API takes a key in the X-Api-Key header. Enrichment is charged per
match and search per record returned. The free plan is meant for testing and
returns contact fields such as emails, phone numbers and street-level
locations only as true/false flags; a paid Pro plan returns their values.
