Using Orderbook Data

The orderbook helps you make informed pricing decisions: 
# Check if there's enough liquidity for your order
gpus_needed = 16
available = sum(level['gpus'] for level in orderbook['asks'])

if available >= gpus_needed:
    print("Sufficient liquidity for market order")
    best_price = orderbook['market_depth']['best_ask']
else:
    print("Insufficient liquidity, consider limit order")

# Calculate estimated cost for market order
cost = 0
remaining = gpus_needed
for level in orderbook['asks']:
    if remaining <= 0:
        break
    take = min(remaining, level['gpus'])
    cost += take * level['price'] * 24  # 24 hour lease
    remaining -= take

print(f"Estimated cost for market order: ${cost}")
