I built a multi-agent coordination system in an automatic routing terminal, driven by Claude Code Agent throughout the process, with the underlying foundation based on Anthropic's Agent SDK. The highlight of this architecture is its ability to capture real-time cost data for various reasoning tasks and support direct conversion into any cryptocurrency units for display. In other words, you can see at any time how much each AI call costs, quantifying this expenditure from the perspective of crypto assets. This is especially interesting for Web3 hedge fund cost management, making every step of automated trading decisions traceable and measurable.
