Use it

Claude Desktop / Cursor / any MCP client (remote server):

{
  "mcpServers": {
    "vextorium": { "url": "https://api.vextorium.com/mcp" }
  }
}

Paid calls need an x402-capable MCP client or wallet (e.g. AgentCash, Coinbase awal). Without one, search_services and service_details still work.

Plain HTTP works too: every service is POST https://api.vextorium.com/v1/<service> with a JSON body. The first call returns HTTP 402 with the price; pay and retry.
