Domain Intelligence X402
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.
