RETIRED: this tool is no longer advertised and serves no flow figures. No spot-Bitcoin-ETF flow source is available that is both key-free and permitted to redistribute, so CoinBucha never had a licensed figure to serve here. It remains callable so existing integrations do not break: it takes no arguments and returns { available: false, status, as_of, date_basis, unit, note, disclaimer }, stating the absence explicitly. Read that absence as absent — never as a zero flow. For live signals use scan_signals, get_sovereign_reserves, get_treasury_holdings, get_hiring_signal, get_network_signal or get_daily_brew. Example: {}. Information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }. This server answers bounded questions, one question, one answer; for bulk, history, backfills and scheduled pulls use the CSVs and datapackage.json at https://coinbucha.com/data.
