A tutorial details how to build a Node.js script to monitor usage accounting for LLM API calls, particularly when using services like Dify and Cursor that share an OpenAI-compatible API gateway. The script records key details such as the base URL, API key owner, model name, HTTP status, response ID, and token usage. This information is crucial for debugging cost spikes, identifying routing errors, and verifying unexpected model changes, providing engineers with a repeatable record to compare against service behaviors. AI
IMPACT Enables better cost management and debugging for applications integrating LLM APIs via shared gateways.
RANK_REASON The item describes a specific technical tool and its implementation for monitoring LLM API usage.
