What are the runtime requirements?

Python 3.10 or higher and the `uv` package manager are required. Optional: Claude Desktop for interactive querying.

How is data presented?

The tool outputs data as a Markdown table with ETF tickers as columns, dates as rows, and a total column for summed flows.

What credentials does it need?

It reads `COINGLASS_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
