Wraps the Alpaca Markets trading API with a hard daily spending cap to keep autonomous agents from blowing through your account. Defaults to paper trading so you can test strategies without risk, but supports live trading if you opt in. Built on the LemonCake payment layer, so each trade settles via USDC permit instead of exposing raw API keys. The guard enforces a daily USD limit you set once during setup, then the agent can execute trades, check positions, and pull market data until it hits the cap. Useful if you want an LLM managing a small trading allocation without giving it carte blanche to your brokerage account.
