All the other RPC methods are working for me, except the validate_address one, which always returns an error. I tried both curl (CLI) and PHP, neither of them work, they return the same error:

{"result":null,"error":{"code":-32700,"message":"Parse error"},"id":null}

If anyone can help, it would be much appreciated.

  • You'll get better help if you edit your question to include the curl and php code that is failing for you.

I'm going to assume you're copying the example from the docs, which has an error in that params should read "params" (quoted).

A corrected and working example looks like:

$ curl localhost:18084/json_rpc -d \
    '{"jsonrpc":"2.0","id":"0","method":"validate_address", "params":{"address":"42go2d3XqA9Mx4HjZoqr93BHspcMxwAUBivs3yJKV1FyTycEcbgjNyEaGNEcgnUE9DDDAXNanzB16YgMt88Sa8cFSm2QcHK","any_net_type":true,"allow_openalias":true}'
  "id": "0",
  "jsonrpc": "2.0",
  "result": {
    "integrated": false,
    "nettype": "mainnet",
    "openalias_address": "",
    "subaddress": false,
    "valid": true
