AgentBudget

Real-time cost enforcement for AI Agents

AI agents can keep calling APIs until a task finishes. If something loops or goes wrong, the bill can grow very fast. There is usually no built in way to stop it. AgentBudget is an open source Python SDK that watches every LLM API call in real time and stops the agent the moment it reaches a set spending limit. You add one import, set a budget, and the agent cannot spend more than that.
