3.2 Why API Key is Needed

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
