Chaining Multiple Tools (via API)

While the n8n node processes one tool at a time, you can use multiple nodes in sequence or call the CleanTextLab API directly for multi-step workflows:

{
  "input": "  HELLO\n  WORLD  ",
  "steps": [
    "trim-lines",
    "lower-case",
    "collapse-spaces"
  ]
}

Result: "hello world"
