## 🎓 Key Learnings
### 1. OpenF1API Is Mostly Free! 🎉
Contrary to concerns, almost everything is accessible:
- ✅ All historical data (2023-present)
- ✅ 21/22 endpoints tested work without authentication
- ❌ Only real-time streaming requires payment
### 2. "401 Errors" Were Misleading
The "401 Unauthorized" errors you saw were actually:
- 422 "No data available" when no session is active
- Poor error handling made them appear as auth errors
- Fixed with proper error handling (returns empty arrays)
### 3. REST API ≠ Streaming API
- **REST API** (HTTP GET requests) - Mostly free
- **Streaming API** (MQTT WebSocket) - Requires paid account
- Your MCP server uses REST API by default - works great!
### 4. Race Weekends Are Key
Live endpoints return 422 when no session is active:
- This is **expected behavior**, not an error
- Test during next race to see live capabilities
- Historical analysis works perfectly year-round
