How to Get Your ChatGPT API Key?

To enable AI features like Smart AI Rewrite and OCR Image AI, you need a valid ChatGPT (OpenAI) API key. Follow these steps to get one:

⚠️ You Must Set Up Billing First

Before you can actually use the key, OpenAI requires billing to be added—even if you’re just exploring or using free trial credits. Many users miss this step and wonder why their API key doesn’t work.

But don’t worry—you can start with as little as $5 to test everything out safely.

🧠 Common Questions – How to Get ChatGPT API Key

1. Can I use the GPT API Key for free?

GPT API Key is not free — there are no trial credits. Although you can create an API key, it won’t work until you add billing information

2. What happens if I lose my key?

You can’t retrieve a lost GPT API key. Revoke it and create a new one via your dashboard.

3. Is $5 enough to test it?

Yes! $5 lets you try out multiple small requests—plenty for experimentation or prototyping.

4. Does using GPT API Key for OCR on images cost more than processing plain text?

Yes. OCR on images consumes significantly more tokens because the model needs to analyze and extract text from the visual data, which is more complex than processing plain text input. As a result, OCR requests generally incur higher costs.

5. Does the length of extracted text affect billing?

Yes. Billing is generally based on tokens processed, so longer extracted text means more tokens and higher costs.
