FX rate
FX rate — Foreign-exchange rate. The ratio used to convert one currency into another. SubRemind refreshes FX rates hourly from open.er-api.com.
An FX rate is the price of one currency expressed in units of another (for example 1 USD = 0.92 EUR). SubRemind fetches the full set of rates relative to your base currency once an hour from open.er-api.com — a free, public endpoint. Rates are cached via Next.js fetch revalidation. They are indicative, not transactional, and intentionally not used for any financial decision-making inside the app.
