Data Sources
We pull exchange rate data from two publicly available, well-established sources:
European Central Bank (ECB) via the Frankfurter API
The ECB publishes reference exchange rates for 30+ currencies on every business day. This data is freely available at ecb.europa.eu and served through the open Frankfurter API. ECB rates are widely used as a benchmark across the financial industry.
fawazahmed0 Currency API
An open-source currency rate aggregator that provides daily updated rates for over 150 currencies. This serves as our primary data source, with the Frankfurter API as a fallback.
Rates are fetched in real-time when you visit any page on this site. We do not store or cache exchange rates on our servers, so you always see the latest available data from these sources.
Historical data is available from 1999 onward, sourced from the ECB dataset, which is one of the longest continuously published exchange rate series in the world.
How We Update Rates
Every time you load a page on this site, your browser sends a request directly to our data providers to fetch the current exchange rate. Here is how the process works:
Primary source
The fawazahmed0 currency API is queried first. This API aggregates rates from multiple sources and updates daily.
Fallback source
If the primary API is unavailable, the site automatically falls back to the Frankfurter API, which delivers ECB reference rates updated on weekdays around 16:00 CET.
No server-side caching
Rates are not stored on our end. Each page load triggers a fresh request, so the data you see is as current as the source APIs allow.
Because ECB rates update once per business day, the rate shown on weekends and holidays reflects the most recent Friday's closing reference rate. For intraday rate movements, professional forex platforms provide more granular data, but for everyday conversion needs our sources are reliable and sufficiently current.
Editorial Standards
- All content is written by humans with financial expertise. We do not publish auto-generated rate commentary.
- Forecasts and market analysis are based on publicly available economic data, central bank announcements, and established analytical frameworks. We cite our sources where possible.
- We clearly distinguish between factual data (exchange rates, historical trends) and editorial opinions (market outlook, service recommendations).
- Service comparisons are based on publicly listed fees and rates. When we link to a service provider, we disclose any affiliate relationship.
- We review and update content regularly to reflect changes in fees, services, and market conditions.
