ColdIQ

"ColdIQ is a unified API for go-to-market data, giving developers, sales teams, and AI agents a single key to 40+ data providers and 700+ endpoints - no more juggling 40 API keys, 40 billing accounts, and 40 response formats.

Built natively for Claude Code and other coding agents, ColdIQ lets you describe what you need in plain language; the agent picks the right provider based on fit, cost, and accuracy, and returns structured, verified data ready to pipe into your CRM, sequencer, or script. It's also available as a REST API with a full OpenAPI spec and an MCP server for direct integration.

Key features: - Unified API access to 40+ GTM data providers (Apollo, People Data Labs, Exa, FullEnrich, Findymail, Wiza, and more) - Lead search, contact/company enrichment, email & phone finding, and verification - Intent signals, technographics, hiring trends, and company intelligence - REST API, MCP server, and natural-language agent chat - 100+ pre-built Claude Code skills encoding full GTM playbooks (targeting, enrichment, sequencing) - Automatic provider routing based on cost and accuracy

Best for: - Developers and AI agent builders shipping GTM data workflows from code - Sales and RevOps teams automating prospecting and enrichment - Agencies and founders running outbound at scale without managing dozens of vendors

Backed by the playbooks behind 300+ client engagements and $50M+ in generated ARR, ColdIQ turns fragmented GTM data sourcing into one simple API call."
