Textutils API

All basic text manipulation tools available via URL endpoints.

🚀 Getting Started

Each function is accessed via its own endpoint:

GET https://textutils.onrender.com/FUNCTION?text=INPUT

Each request returns a JSON response like this:

{
  "input": "The original input to 'text' parameter",
  // Other applicable parameters (length, etc...)
  "result": "The transformed output",
}

Example

Request

GET https://textutils.onrender.com/uppercase?text=hello world

Response

{
    "input": "hello world",
    "result": "HELLO WORLD"
}

All functions take the parameter text as input.

And some functions require extra parameters.
