Common Issues

• API key authentication errors - Verify your API key is correct and has proper permissions
• Forgot password - Use the "Forgot Password?" link on the login page to reset your password via email
• Password reset email not received - Check your spam folder, verify your email address, and ensure email service is configured
• HTTP 402 Payment Required - If you receive 402 responses, ensure your SDK client is configured with a signer for automatic handling
• Signer issues - In a browser, make sure your wallet (e.g. MetaMask) is installed and unlocked; on a server, that your private-key signer is set
• Payment signing failures - Verify you're connected to the correct network (Base, Ethereum, or Polygon)
• Webhook delivery issues - Check your webhook endpoint is accessible and returns 200 status
• Payment verification failures - Ensure your payment data matches the expected format
• Network connectivity - Verify your application can reach our API endpoints
• GraphQL payment extensions - Check the extensions.paymentRequired field in GraphQL responses for payment requirements

BillMyAgent fully implements the x402 protocol for autonomous agent payments. Key features include:

• HTTP 402 Paywalls: Endpoints can require payment and return 402 with payment instructions
• Automatic Payment Handling: SDKs automatically detect 402, sign payments, and retry requests
• Signer-based payments: Sign with any viem wallet client (browser wallet) or a server-side private key (EIP-3009)
• GraphQL Extensions: Field-level monetization with extensions.paymentRequired
• Payment Instructions: Automatic generation of x402-compliant PaymentRequired payloads
