Humanization API

The UndetectedGPT API lets you humanize AI-generated text programmatically. Send text in, get human-sounding output back with multilingual support, tone control, and stealth mode.

Quick example

One API call is all you need. Send your text and get back a humanized version.

curl -X POST https://www.undetectedgpt.ai/api/v1/humanize \
  -H "Authorization: Bearer ugpt_live_..." \
  -H "Content-Type: application/json" \
  -d '{"text": "Your AI-generated text here"}'

Response includes the humanized output, words used, and your remaining balance.

{
  "output": "Your humanized text...",
  "words_used": 6,
  "words_remaining": 249994
}
