AgentBudget – Real-time cost enforcement for AI Agents

Summary: AgentBudget is an open source Python SDK that monitors LLM API calls in real time and stops AI agents once a predefined spending limit is reached, preventing unexpected high costs.

What it does

It tracks every API call made by AI agents and halts execution immediately when the set budget is exceeded, requiring only a simple import and budget initialization.

Who it's for

Developers and users running AI agents who need to control and limit their API spending during automated tasks.

Why it matters

It prevents runaway costs caused by loops or errors in AI agents by enforcing strict spending limits in real time.
