Summary
This server turns email addresses into full contact profiles through the x402 micropayment network. You get back names, job titles, company information, and social media profiles without managing API keys or subscription tiers. Each lookup costs USDC micropayments processed through the x402 protocol, so you pay per enrichment rather than committing to monthly plans. The implementation uses server-sent events for transport and connects to the Klymax402 API backend. Reach for this when you're building lead qualification flows, CRM enrichment pipelines, or any agent workflow where you need to resolve an email into a person's professional identity without the overhead of traditional data provider contracts.
