# Deploy token-aggregation service for publication (token lists, CoinGecko/CMC reports, bridge/routes).
# Run on explorer VM (VMID 5000) or host that serves explorer.d-bis.org.
#
# Prerequisites: Node 20+, PostgreSQL (for full indexing; API responds with defaults if DB empty)
# Usage: ./scripts/deploy-token-aggregation-for-publication.sh [INSTALL_DIR]
#
# After deploy: nginx must proxy /api/v1/ to this service BEFORE Blockscout (see TOKEN_AGGREGATION_REPORT_API_RUNBOOK).
# Explorer layouts vary: port 3000 or 3001 — match TOKEN_AGG_PORT in apply-nginx scripts.
