Astro SSG showcase site with a hybrid XMLCharts plus FXCM API, a secure admin dashboard and precious-metal prices refreshed every 10 seconds.
Golden Cash's previous system had several limitations. Precious-metal prices were not refreshed in real time, forcing clients to call to confirm a rate before each transaction. The admin interface was not properly secured, and occasional bugs affected the public display. For a business where trust and responsiveness on rates are essential, these flaws held back online conversion.
A complete rebuild on Astro 5 in SSG for performance and deployment simplicity. On the backend, a PHP API acts as a hybrid proxy between two precious-metal price sources: XMLCharts as the primary source and FXCM as an automatic fallback. A 10-second cache limits paid calls while guaranteeing freshly validated rates. The public estimator calculates buy-back in real time based on weight and carat, and a JWT-secured admin dashboard lets the Golden Cash team switch between API sources, adjust margins, override EUR/CHF rates or manually freeze prices in seconds.
