try:
    # Register and login
    token = client.auth.login(username="user", password="pass")
    client.set_token(token.access_token)

    # Get wallet balance
    wallet = client.blockchain.get_wallet()
    print(f"Balance: {wallet.balance} RoadCoin")

    # Mine a block
    block = client.blockchain.mine_block()
    print(f"Mined block #{block.index}")

finally:
    client.close()
```

```python
import asyncio
from blackroad import AsyncBlackRoadClient

async def main():
    async with AsyncBlackRoadClient(base_url="http://localhost:8000") as client:
        # Login
        token = await client.auth.login(username="user", password="pass")
        client.set_token(token.access_token)

        # Concurrent operations
        wallet, stats, agents = await asyncio.gather(
            client.blockchain.get_wallet(),
            client.blockchain.get_stats(),
            client.agents.list_agents(category="devops")
