## 🔧 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=CG-LxMsQ7jp3Jd6he3VFzP1uUXA`
  - `DATA_SOURCE_1_URL` with API key in URL
  - `DATA_SOURCE_1_PARSER=ethereum.usd`
- Restarts oracle-publisher service

**To run:**
```bash
cd /home/intlc/projects/proxmox
./scripts/update-oracle-publisher-coingecko-key.sh
```

**Or manually:**
```bash
ssh root@192.168.11.10
pct exec 3500 -- bash
cd /opt/oracle-publisher
nano .env
# Add/update:
# COINGECKO_API_KEY=CG-LxMsQ7jp3Jd6he3VFzP1uUXA
# DATA_SOURCE_1_URL=https://api.coingecko.com/api/v3/simple/price?ids=ethereum&vs_currencies=usd&x_cg_demo_api_key=CG-LxMsQ7jp3Jd6he3VFzP1uUXA
# DATA_SOURCE_1_PARSER=ethereum.usd
systemctl restart oracle-publisher
```

---

## ✅ Verification Steps

### 1. Verify Root .env

```bash
grep COINGECKO_API_KEY .env
# Should show: COINGECKO_API_KEY=CG-LxMsQ7jp3Jd6he3VFzP1uUXA
```

### 2. Verify Token Aggregation .env

```bash
cd smom-dbis-138/services/token-aggregation
grep COINGECKO_API_KEY .env
# Should show: COINGECKO_API_KEY=CG-LxMsQ7jp3Jd6he3VFzP1uUXA
```

### 3. Test API Key

```bash
# Test Bitcoin price
curl -s "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd&x_cg_demo_api_key=CG-LxMsQ7jp3Jd6he3VFzP1uUXA" | jq .

# Test Ethereum price
curl -s "https://api.coingecko.com/api/v3/simple/price?ids=ethereum&vs_currencies=usd&x_cg_demo_api_key=CG-LxMsQ7jp3Jd6he3VFzP1uUXA" | jq .
```

### 4. Verify Oracle Publisher (if accessible)

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