Developer API

The same operations as the website, over HTTP, for scripts and pipelines. Free to use, no key required.

Endpoint

POST https://devclean-backend.onrender.com/api/process
Content-Type: application/json

{
  "text": "apple\nbanana\napple",
  "option": "remove_duplicates",
  "options": { "ignoreCase": true }
}

The response is a JSON object:

{ "processed_text": "apple\nbanana", "operation": "remove_duplicates" }

Example with curl

curl -X POST https://devclean-backend.onrender.com/api/process \
  -H "Content-Type: application/json" \
  -d '{"text":"a\nb\na","option":"remove_duplicates"}'

Example in Python

import requests

r = requests.post(
    "https://devclean-backend.onrender.com/api/process",
    json={"text": open("list.txt").read(), "option": "remove_duplicates"},
    timeout=30,
)
print(r.json()["processed_text"])
