Lusha API
Lusha documents four REST product APIs at docs.lusha.com: Enrichment, Prospecting, Signals, and Lookalike, plus webhooks and an MCP server. Keys are generated in the admin console, but API access effectively requires the Scale plan. Samples ship in cURL, Node, Python, and Java.

Lusha has a workable official integration path. Most engineering teams can build against it directly. Solid API with minor gaps
Lusha is a B2B contact data and sales intelligence platform that supplies verified emails, mobile phone numbers, firmographics, technographics, and buying signals to go-to-market teams.
Primary vertical: misc (cross-industry B2B sales intelligence / GTM tooling). An SDR opens a LinkedIn profile and clicks the Lusha Chrome extension to reveal a verified mobile number and work email, which is one-click pushed into Salesforce or HubSpot and queued into an Outreach / Salesloft sequence.
High in the SDR / SMB segment, mid in the enterprise.
Lusha is the contact-and-signal layer feeding pipeline generation.
Founded in 2016, the platform has been continuously modernized: the original Chrome-extension-plus-CRM-push workflow has been extended into Lusha Workspace, Lusha Plays, a public REST API surface (docs.lusha.com) split across Enrichment / Prospecting / Signals / Lookalike, a published MCP server for agentic AI consumers, webhooks for real-time event delivery, and native integrations with Salesforce, HubSpot, Zoho, Outreach, Salesloft, Gong, Zapier, Make, n8n, and Workato.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
