I need a Claude API key, but I have searched a lot and still could not find it. I also checked the Claude website, but I did not see any option to create an API key.
Do I need to get the API key from another website, or do I have to use the Anthropic Console?
I searched for the Anthropic Console, but I still don't understand how to create a Claude API key. Can I use the Claude API for free, or is it paid? Is there any free usage limit, or is it permanently free?
Please explain the complete process step by step.

You can get a Claude API key from the Anthropic Console. New users usually receive $5 in free API credits, which you can use for testing and learning. Once your free credits are used, you need to add billing to continue using the Claude API.
Follow the steps below to create your Claude API key.
First, open the Anthropic Console and create a new account. You can also sign in using your Google account.
After signing in, you may see different credit options, such as $5, $20, $25, or $100. If a welcome screen appears, simply skip it and continue to the dashboard.
From the left sidebar, click on API Keys.
Now click Create API Key, enter any name for your key, choose the expiration option if required, and create the key.
Your API key will be displayed on the screen. Copy it and save it in a safe place. You can now use this API key in your PHP, Python, Node.js, WordPress, or any other project.
Claude API comes with limited free credits for testing. If you need more usage after your free credits are finished, click on Set Up Billing in the Anthropic Console and add a payment method.
After adding billing, your API usage limit will increase, and you can continue using the Claude API in your projects.
This is how you can create a Claude API key from the Anthropic Console and use it in your applications.
The free $5 API credits are enough for testing and learning. The number of requests depends on which Claude model you use.
Claude 3.5 Haiku / Haiku 4.5: Good for lightweight tasks. You can test thousands of simple prompts.
Claude 3.5 Sonnet / Claude 3.7 Sonnet: Best for coding and more complex text generation. You can usually test around 200–400 prompts, depending on the size of your requests.
Testing Projects: The free $5 credits are usually enough to test your application, website, or API integration before going live.
Once your $5 free credits are used, or if you want to use the Claude API in a production project, go to the Plans & Billing section in the Anthropic Console and add your credit card or debit card.
After adding billing, you can continue using the Claude API without the free credit limit.
