Anthropic (Claude)
Anthropic's Claude models — strong reasoning, balanced for everyday use.
1. Create an Anthropic account
Open the link below, then click Sign Up in the top right. You can sign up with Google or with email and password. Complete the email verification.
2. Configure billing
In the left sidebar of the console click Settings, then Billing. Add a credit card and top up your balance — even just $5 is enough to get started.
3. Open API Keys
In the left sidebar click API Keys. You will see a list (empty the first time). Click the + Create Key button in the top right.
4. Create and copy the key
Give the key a name (e.g. youkore) and confirm. The key will only be shown once — copy it immediately before closing!
Anthropic has no free tier for APIs. Prepaid credits are required, but with $5 you can make thousands of calls with the lighter models (Haiku).
