Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

{
  "mcpServers": {
    "tech-enrichment": {
      "url": "https://tech-enrichment.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl "https://tech-enrichment.api.klymax402.com/api/detect?url=https://example.com"
# -> 402 Payment Required, with an x402 payment challenge in the response body
