Generate API Keys

Click Get API keys and add credits (minimum $5) to generate an API key.
Anthropic API is a paid service that charges based on token usage, deducting costs from your prepaid credits. The minimum credit purchase is $5. For detailed pricing by model, see the Pricing page.
API keys can only be viewed immediately after generation, so be sure to store it securely. If you lose your API key, you can delete the existing key from the dashboard and generate a new one.

Add Models

Once you’ve registered an API key, you can add additional Anthropic models beyond the default ones. Simply provide a display name (shown in chats) and the official Anthropic model name.
You can find the list of model names available via API on the All models overview page. The highlighted section in the screenshot below shows the model name format.
