This is a curated collection from xpay's 980+ tool catalog, focused on about 50 lead generation endpoints across Apollo, Hunter, Tomba, Sixtyfour, Fiber, Exa, and Nyne. You connect with one API key and pay $0.01 per call in USDC on Base via the x402 protocol. Instead of juggling seven different provider accounts and subscriptions, you get streamable HTTP access to email finders, contact enrichment, and prospect research tools through a single endpoint. The payment model is straightforward: add USDC credits to your xpay wallet, and each tool invocation automatically deducts a penny. If you're building lead workflows in Claude Desktop or similar MCP clients and want unified access without the API key sprawl, this bundles the main players into one connection.
