## ✅ Quick Answer
|
||
|
|
|
||
|
|
**Do you need API keys?**
|
||
|
|
|
||
|
|
- **CoinGecko**: Optional but **recommended** (higher rate limits)
|
||
|
|
- **Binance**: Not needed (removed - geo-blocked anyway)
|
||
|
|
- **CryptoCompare**: No API key needed (now used as alternative)
|
||
|
|

|
|
## 🔧 Current Configuration (After Fix)
|
||
|
|
|
||
|
|
The service now uses:
|
||
|
|
1. **CoinGecko** - Can work without API key, but you'll hit rate limits (429 errors)
|
||
|
|
2. **CryptoCompare** - No API key needed, works globally
|
