How this service works
Daily ECB reference exchange rate of a currency against the euro for up to 5 years: latest, change, high, low, average and annualized volatility, with the series.
Output
A JSON object containing the currency pair label, latest date and rate (units per EUR), percentage change over the period, maximum and minimum rates, average rate, annualized volatility percentage, the start date of the series, the data source (European Central Bank), and a full array of daily {date, value} data points.
Example use cases
Quarterly FX report for finance team
“Pull the EUR/GBP exchange rate data for the last 90 days — I need the latest rate, percentage change, high, low, average, and the full daily series so I can put together a quarterly currency report.”
Volatility check before hedging decision
“What's the annualized volatility of EUR/JPY over the past year? Also give me the high, low, and average rate — I'm trying to decide whether to hedge our yen exposure.”
Long-term EUR/USD trend analysis
“Can you get me 5 years of daily EUR/USD exchange rate history from the ECB? I want to see the full series along with the average, high, low, and how volatile it's been annually.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/eur-fx-history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official ECB reference exchange rates (not market rates) for EUR-denominated currency pairs, especially when you want statistical summaries (high, low, average, volatility) alongside the full daily time series. Prefer this over generic FX APIs when ECB provenance and historical depth (up to 5 years) are required, such as for regulatory reporting, accounting, or macroeconomic analysis.
Side effects
- Invalid or unsupported ISO currency code returns an error or null values
- Days parameter outside the 5–1825 range may cause a validation error
- ECB may not publish rates for all currencies (exotic currencies may return empty series)
- Weekends and ECB holidays have no published rates, so the series may have gaps
- Network or payment authorization failures return non-200 HTTP status codes
