🔧 Oracle Publisher Service

Automated Update Script Created ✅

Script: scripts/update-oracle-publisher-coingecko-key.sh

What it does:

• Connects to Proxmox host (192.168.11.10)
• Accesses Oracle Publisher container (VMID 3500)
• Updates /opt/oracle-publisher/.env with:
  • COINGECKO_API_KEY=your-coingecko-api-key
  • DATA_SOURCE_1_URL with API key in URL
  • DATA_SOURCE_1_PARSER=ethereum.usd
• Restarts oracle-publisher service

To run:

cd /home/intlc/projects/proxmox
./scripts/update-oracle-publisher-coingecko-key.sh

Or manually:

ssh root@192.168.11.10
pct exec 3500 -- bash
cd /opt/oracle-publisher
nano .env
# Add/update:
# COINGECKO_API_KEY=your-coingecko-api-key
# DATA_SOURCE_1_URL=https://api.coingecko.com/api/v3/simple/price?ids=ethereum&vs_currencies=usd&x_cg_demo_api_key=your-coingecko-api-key
# DATA_SOURCE_1_PARSER=ethereum.usd
systemctl restart oracle-publisher

---

✅ Verification Steps

1. Verify Root .env

grep COINGECKO_API_KEY .env
# Should show: COINGECKO_API_KEY=your-coingecko-api-key

2. Verify Token Aggregation .env

cd smom-dbis-138/services/token-aggregation
grep COINGECKO_API_KEY .env
# Should show: COINGECKO_API_KEY=your-coingecko-api-key

3. Test API Key

# Test Bitcoin price
curl -s "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd&x_cg_demo_api_key=your-coingecko-api-key" | jq .

# Test Ethereum price
curl -s "https://api.coingecko.com/api/v3/simple/price?ids=ethereum&vs_currencies=usd&x_cg_demo_api_key=your-coingecko-api-key" | jq .

4. Verify Oracle Publisher (if accessible)

ssh root@192.168.11.10 "pct exec 3500 -- grep COINGECKO /opt/oracle-publisher/.env"
# Should show the API key
