Credits and Wallet Documentation

MuAPI uses a transparent, credit-based system to manage API consumption and feature access.

How it Works

1. The Credit Wallet

Every user has a personal CreditWallet. All AI generations (tasks) deduct a specific amount of credits based on the model's cost and usage duration.

2. Usage Tracking

The UsageLog provides a complete history of every API call, including:

• Cost: The exact credits deducted.
• Status: (Pending, Processing, Completed, Failed).
• Data: Snapshots of the input parameters and resulting outputs.

Purchasing Credits

MuAPI integrates with Stripe for secure credit top-ups.

• Workflow:
  1. Call GET /api/payments/create_credits_checkout_session with your desired amount.
  2. Complete the purchase on the secure Stripe hosted page.
  3. Your credits are automatically added to your wallet upon successful payment.
