Lusha is a B2B sales-intelligence platform that sells verified contact and company data, buying signals and AI recommendations to revenue teams. Its v3 REST API at api.lusha.com exposes 58 operations across thirteen resource families — Search, Enrich, Search & Enrich, Prospecting, Lookalikes, Buying Group, Contacts Tables, Companies Tables, Signals, Website Visits, Filters, Webhooks and Account — behind a single `api_key` header credential, on a search-then-enrich pattern where previews are free of PII and reveals spend credits. Lusha also ships a first-party hosted MCP server at mcp.lusha.com with 22 tools, OAuth 2.1 discovery and official Claude, ChatGPT and Codex connectors, plus HMAC-signed webhooks for real-time signal delivery.
