3.2 Why API Key is Needed

Don't want to deal with too many technical details?

Just subscribe. After subscribing, you can freely switch among the AI services MiniTavern already supports, staying flexible with multiple options. Because billing rules differ by model and each uses a different multiplier, pick a model that fits your budget.

What is an API Key?

An API Key (Application Programming Interface Key) is a unique string, like your "account password", used for:

• Authentication - Proves you are a paying user
• Usage Statistics - Records your usage
• Billing - Deducts fees based on usage
• Security Control - Prevents unauthorized use

Why Purchase Separately?

Each AI service provider operates independently:

• Each company has its own technology and costs
• Needs to pay for servers, computing power, R&D, etc.
• Requires separate account systems to manage users
• Has different pricing strategies and service quality

Analogy:

This is like using different streaming services (Netflix, Disney+); each platform requires a separate subscription because the content and services they provide are independent.

Security

• API Keys are stored only on your local device
• MiniTavern does not upload your keys
• Conversation requests are sent directly to AI service providers
• MiniTavern cannot access your conversation content
