Create an account
Create an account on SuperHumanizer. You can find your API key on this same page and view your remaining word count. There is nothing else to learn.
Generate your key
Click once and you are done. We show your key once and then store it encrypted, so save a copy somewhere safe. We will not be able to display your key ever again.
Send your first request
Copy any of the above examples, insert your key and run it. You can use your 1,000 free words immediately.

Built for production
One endpoint, one request
Send your text, get humanized text back. There's no need to install anything or configure settings.
The same engine as our app
Your input is processed using the identical models underlying SuperHumanizer. You're getting the full version, not a scaled-down one.
Automatic failover
Should one model happen to be busy, your request will automatically be diverted to another one. You just get your text back.
Pay for words, not requests
One 5,000 word document costs the same as ten 500 word documents. You can send us your content whichever way works best for you.
Top up any time
Run out before your month is up? Simply purchase more words, and they will be added to your existing word balance without affecting your plan.
No surprise bills
Once your words run out, the API will let you know and stop. You will never be charged any overage fees.
