Agentic Ledger: Cost Control and Monitoring for AI Agents

Description and use

Agentic Ledger is a tool for monitoring and controlling AI agent costs. It tracks calls in real-time and automatically stops agents when a spending limit is reached, preventing unexpected bills. It operates locally, supporting OpenAI, Anthropic, Azure, and AWS Bedrock.

Problem

AI agents running unsupervised can incur unexpected and high costs (e.g., a $6,000 bill) because there is no mechanism to monitor activity in real-time or enforce spending limits.

Outcome

The Agentic Ledger provides real-time visibility into AI agent costs and actions, allowing developers to set hard cost limits that automatically stop agents from incurring further charges. It operates locally, ensuring prompts do not leave the machine.

Workflow

• Install the tool using pip install agentic-ledger.
• Configure the ledger to intercept calls from supported providers (OpenAI, Anthropic, Azure, AWS Bedrock).
• Set a cost ceiling for specific agent runs.
• Monitor real-time spending and call logs locally.
• Allow the proxy to automatically refuse further calls if the cost limit is hit.

Evidence

Someone left an AI agent running overnight and woke up to a $6,000 bill. Nothing was watching, and nothing could say no.

Source

When spend hits the number, the proxy refuses the next call. It costs nothing to be told no.
