Greek Banking Integration

This skill provides comprehensive integration with the Greek banking system through practical file processing of bank statements, transaction data, and payment confirmations from all major Greek financial institutions.

Setup

export OPENCLAW_DATA_DIR="/data"
which jq || sudo apt install jq
mkdir -p $OPENCLAW_DATA_DIR/banking/imports/{alpha,nbg,eurobank,piraeus}

No bank API credentials required. This skill parses bank statement files (CSV/Excel) that you export manually from your bank's web portal and place in the imports directory. Supported banks: Alpha Bank, National Bank of Greece, Eurobank, Piraeus Bank.

Core Philosophy

• Real Greek Bank Focus: Built for actual Greek bank statement formats and business practices
• File-Based Processing: Process exported bank data files, not complex banking APIs
• OpenClaw Native: Designed specifically for OpenClaw's file processing strengths
• Production Testing Ready: Suitable for VM testing and real Greek company deployment
• All Major Banks: Alpha Bank, National Bank, Eurobank, Piraeus, and regional banks
