Summary
This connects Claude to a cost calculator for AI APIs across 29 models from OpenAI, Anthropic, Google, and DeepSeek. You get tools to calculate token costs, compare models, and see recommendations based on requirements like "fast cheap coding". It handles the math for platform fees when you're using aggregators like OpenRouter versus going direct, and converts prices to local currencies with real-time exchange rates. Reach for this when you're optimizing AI spend, evaluating which provider or gateway makes sense for your usage patterns, or need your agent to factor costs into model selection decisions during development.
