# Deploy token-aggregation service for publication (token lists, CoinGecko/CMC reports).
# Run on explorer VM (VMID 5000) or host that serves explorer.d-bis.org.

# Prerequisites: Node 20+, PostgreSQL (for full indexing; report API may work with minimal config)
# Usage: ./scripts/deploy-token-aggregation-for-publication.sh [INSTALL_DIR]
#
# After deploy: Run apply-nginx-token-aggregation-proxy.sh to proxy /api/v1/ to this service.
