Lusha B2B Data API provides programmatic access to contact and company records, prospecting, enrichment, lookalike discovery, and business-change signals.
Lusha B2B Data API gives sales, marketing, and revenue teams programmatic access to contact and company information for prospecting and record enrichment. Its REST endpoints support searching and filtering prospects, retrieving full profiles, identifying buying-group contacts, and finding lookalike companies and contacts.
Teams can use contact and company activity signals to monitor job changes, hiring, business events, and technology adoption, then synchronize those data into customer systems and automated workflows. The API documentation describes real-time and bulk use cases, usage controls, and webhook notifications for relevant changes.
