Ocr space free api

I have received FREE OCR API code via email but I don’t know how to use it, please guide me through the system I would like to convert pdf to text

Hello, do you have some coding experience? I ask because this is an OCR API, so it is usually used by a script or a program.

Example code: Free OCR API

For manually converting PDF to text, you can use our ocr.space front page.
