## 🔧 Services Using CoinGecko API Key
|
|
|
|
### 1. Token Aggregation Service
|
|
|
|
**Service:** `smom-dbis-138/services/token-aggregation/`
|
|
**Adapter:** `src/adapters/coingecko-adapter.ts`
|
|
|
|
**How it works:**
|
|
- Reads `COINGECKO_API_KEY` from environment
|
|
- Uses Pro API endpoint when key is present
|
|
- Sends key in header: `x-cg-pro-api-key`
|
|
|
|
**Benefits:**
|
|
- Higher rate limits
|
|
- More reliable token data fetching
|
|
- Better market data enrichment
|
|

|
### 2. Oracle Publisher Service
|
|
|
|
**Service:** VMID 3500 (Oracle Publisher Container)
|
|
**Location:** `/opt/oracle-publisher/.env`
|
|
|
|
**Configuration:**
|
|
```bash
|
|
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
|
|
```
|
|
|
|
**Note:** Oracle Publisher uses the key in the URL parameter format (`x_cg_demo_api_key`).
