Request: Add CryptoIZ MCP to Marketplace / Bazaar

[dadang11]

Hi Merit-Systems team,

I'd like to register CryptoIZ MCP Server for the x402scan Marketplace. The UI registration fails with "Missing input schema" even though my server returns what appears to be a compliant x402 v1 response with inputSchema field in each accepts entry.

Question

Could you document the exact expected shape for inputSchema on Solana x402 v1 endpoints? Our current shape follows the JSON Schema spec:

{
  "inputSchema": {
    "type": "object",
    "properties": {
      "tool": { "type": "string" },
      "args": { "type": "object" }
    },
    "required": ["tool"]
  }
}

Happy to adjust if there's a specific canonical format x402scan expects. Thanks!
