LeadIQ
LeadIQ is a B2B sales intelligence and contact data platform headquartered in Santa Clara, California (with engineering in Singapore and Brisbane) that helps outbound sales teams identify, capture, enrich, and engage prospects across Salesforce, HubSpot, Outreach, Salesloft, Gong, and other revenue tools. The product portfolio includes Prospector (Chrome extension for contact capture with verified work emails and direct-dial mobile phones), Scribe (AI message writer), Refresh / CRM Enrichment (continuous contact and account hygiene for Salesforce and HubSpot), Champion Tracking (job-change alerts on existing contacts), AI Account Prospecting (ICP-fit account and persona discovery), and Lando — an agentic AI assistant that fuses first-party CRM data with LeadIQ's third-party intelligence behind a conversational interface. LeadIQ exposes a public GraphQL Data API at https://api.leadiq.com/graphql for programmatic people search, company search, advanced grouped search, prospect-list management, usage reporting, and data-feedback submission, authenticated via HTTP Basic auth with an API key issued in the LeadIQ dashboard. The same API surface is also reachable through a Model Context Protocol (MCP) server so AI agents (including Claude) can query verified contact and account data conversationally. LeadIQ actually runs three programmable surfaces over one data core: the GraphQL Data API, a REST Prospector API at https://prospector.leadiq.com described by an OpenAPI 3.1.0 document LeadIQ serves publicly (14 operations for lists, prospects, email verification, Salesforce export and caller identity), and a remote MCP connector at https://mcp.leadiq.com/mcp with seventeen tools behind OAuth 2.0 and dynamic client registration. The published rate limit is 60 requests/minute (Standard), with credit-based metering in Universal Credits where a verified work email costs 1 UC, a direct phone 10 UC, company firmographics 3 UC and a profile 0.1 UC. All plans get 50 one-off test calls; sustained API access is sales-gated.
LeadIQ publishes 2 APIs on the APIs.io network: GraphQL API and Prospector REST API. Tagged areas include Sales Intelligence, B2B Data, Contact Data, Lead Generation, and Prospecting.
LeadIQ’s developer surface includes authentication, documentation, API reference, getting-started guide, pricing, signup flow, engineering blog, and 44 more developer resources.
