Use these prompts in Claude to interact with Nigerian bank accounts via the Mono API.
- "List all my linked bank accounts"
- "Show me the balance for account [account_id]"
- "Get my last 20 transactions for account [account_id]"
- "Verify the account name for account number 0123456789 at Zenith Bank"
- "Initiate a payment of ₦5000 to account 0123456789"
- "Display all supported Nigerian banks and their codes"Troubleshooting Mono
Authentication errors when calling Mono API tools
Verify that MONO_API_KEY in your .env is correct and that your Mono account has the appropriate permissions for the operations you are attempting (read-only vs. payment initiation requires different access levels).
Database errors on startup
Ensure DATABASE_URL is set correctly. For local development, sqlite:///./mono.db creates a file-based SQLite database in the project directory with no extra setup. For PostgreSQL, ensure the database exists and the connection string is correct.
Webhook signature verification failures
Confirm that MONO_WEBHOOK_SECRET matches exactly what is configured in your Mono dashboard. HMAC verification is sensitive to whitespace and encoding; copy the secret directly from the Mono developer console.
