Your AgentPay balance is your universal payment method for all MCP Servers, making using them incredibly simple and secure.

​
Viewing Your Balance

Your current balance is always visible in the top-right corner of the AgentPay Hub. This balance:
  • Works across all MCP Servers you use.
  • Is used after any Server-specific free credits are consumed.
  • Shows any outstanding payments that need to be covered.

​
Adding Funds

To add funds to your AgentPay balance:
  1. Click the “Top Up” button next to your balance in the Hub header.
  2. Enter the amount you wish to add.
  3. Select your preferred payment method:
    • Credit cards (via Stripe)
    • USDC on Base (stablecoin)
  4. Complete the payment process.
We currently support credit cards through Stripe and USDC on Base for balance top-ups. We’re working on adding more payment methods in the future, including automatic top-up.

​
Understanding Free Credits

When you first get an API Key for a Server:
  • You’ll receive $1.00 in free credit to test out the Server.
  • This free credit is specific to that Server only, and only available the first time you get an API Key for it.
  • Once you use up the free credit, you’ll start consuming from your AgentPay balance.

​
Balance and API Keys

Your AgentPay balance directly affects your API Keys:
  • Positive Balance: All your API Keys remain active and can be used.
  • Zero Balance: API Keys will be invalidated until you add funds.
  • Outstanding Payments: If a Server usage fails due to insufficient funds:
    1. The payment is recorded as outstanding.
    2. Your API Key is invalidated.
    3. When you add funds, outstanding payments are automatically paid first.
    4. Your API Key is reactivated once payments are complete.

​
Best Practices

  • Monitor Regularly: Check your balance in the Hub header to ensure you have sufficient funds.
  • Plan Ahead: Add funds before your balance gets too low to avoid service interruptions.
  • Check Usage: Review your usage in the “My API Keys” tab to understand your spending patterns.
  • Set Reminders: Consider setting up notifications for low balance alerts.
