Email Finder API
Connects to the email-finder-x402 API to look up professional email addresses when you have a person's name and their company domain. Uses the x402 micropayment protocol with USDC to pay per lookup, so you're not locked into a subscription for occasional use. The MCP server exposes the lookup operation through a remote SSE transport hosted at email-finder.api.klymax402.com. Reach for this when you need to programmatically find contact information during prospecting, research, or outreach workflows where you know the company but not the specific email format. The pay-per-call model makes sense if you're doing sporadic lookups rather than bulk operations.
