Summary
Reach for this when you need domain reconnaissance data in a single call instead of stitching together multiple lookup tools. It bundles WHOIS records, DNS lookups, and SSL certificate details behind one MCP interface, so Claude can pull comprehensive domain intelligence without juggling separate APIs. The server runs remotely at domain-intelligence.api.klymax402.com and uses x402 USDC micropayments, meaning you pay per request rather than committing to a subscription. Useful for security research workflows, due diligence checks, or any agent task that needs to understand a domain's technical footprint without manual tool hopping.

Domain Intelligence API
Domain intelligence in one call: WHOIS, DNS records, SSL certificate, domain age. Essential for due diligence and security audits. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
{
"mcpServers": {
"domain-intelligence": {
"url": "https://domain-intelligence.api.klymax402.com/mcp"
}
}
}
Quickstart -- HTTP (x402)
curl "https://domain-intelligence.api.klymax402.com/api/lookup?domain=..."
# -> 402 Payment Required, with an x402 payment challenge in the response body
Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.
