How the Currency Converter works
On first successful load the page requests the currency dictionary and latest rates for your chosen base (defaulting to USD) via Dynamic Duniya `/api/currency/currencies` and `/api/currency/latest`, which server-fetch Frankfurter and return JSON to the browser—avoiding third-party CORS restrictions. The numeric map plus API date stamp are cached in localStorage for about an hour. Conversion multiplies or divides through the shared base according to standard cross-rate formulas, and Intl.NumberFormat renders locale-aware currency symbols where the browser knows them. A comparison table lists either a curated popular set or every quote returned for the active base, and clicking a row promotes that currency to the target slot for faster exploration.
GEO and travel context
Travelers, freelancers invoicing overseas clients, and small-business finance staff routinely need mid-market references before walking into a bureau that adds spreads. Showing ECB-linked wholesale numbers clarifies expectations for readers in the Eurozone, the United Kingdom, India, Southeast Asia, and the Americas even though retail kiosks will still mark up the rate.
Privacy and limitations
Your typed amounts stay client-side. Exchange-rate metadata is fetched same-origin through Dynamic Duniya’s `/api/currency` proxy, which forwards requests to Frankfurter on the server so browsers are not blocked by third-party CORS policies. This page is informational—not a trading venue—and reflects the API’s publication date, not millisecond FX trading feeds.
