What powers each number, how often it refreshes, and what this product is not.
All upstream calls run server-side through Next.js route handlers with ISR-style revalidation: FX and market quotes refresh hourly, official CBU rates twice daily, and World Bank macro series once a day. Keys are read from the server environment and never reach the browser.
Frankfurter, the World Bank and the Central Bank of Uzbekistan need no credentials and are live out of the box. FRED and Alpha Vantage require a free key; until one is supplied those panels render clearly-labelled sample data.
Pulse is an information tool, not financial advice. Figures are sourced from public APIs and may be revised, delayed, or incomplete. Exchange rates are official reference rates and will differ from the rates offered by commercial banks and exchange bureaus. Do not rely on this dashboard for trading, accounting, or regulatory purposes.
