The system will automatically map short codes to full codes.\n\n## Validation Process\n1. User provides bank code, account number, and account name\n2. System maps bank code (adds `bank_` prefix if needed)\n3. System calls primary external bank validation API with retry logic (up to 2 retries)\n4. If primary API fails, automatically falls back to secondary API\n5. If account is found, server returns account holder name\n6. System performs fuzzy matching between user-provided name and server name\n7. If match score >= 7.0, validation is successful\n8. Server name is masked for privacy (first 3 characters + ****)\n\n## Response Fields\n- **is_valid**: Boolean indicating if account validation passed\n- **score**: Float value (0.0 to 10.0) representing name match confidence\n- **name**: Masked account name showing first 3 chars + **** (only if valid, null if invalid)\n- **message**: Status message describing the validation result\n- **note**: Additional note (empty string if valid, \"Name was not returned\" if validation failed)\n\n## Use Cases\n- Payment gateway account verification\n- E-wallet registration\n- Financial service onboarding\n- KYC (Know Your Customer) compliance\n- Account ownership verification\n- Fraud
