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 (e.g. EUR/USD), start and end dates, the source attribution (European Central Bank), units per euro (latest rate), percentage change over the period, maximum and minimum rates, average rate, annualized volatility percentage, and the full daily time series as an array of date-value objects.

Example use cases

Currency volatility risk assessment

“Can you pull the ECB official exchange rate data for JPY against the euro for the past year and tell me the annualized volatility, the high and low, and the percentage change over that period?”

Monthly FX report for finance team

“Get me the daily ECB EUR/GBP rate series for the last 90 days including the average rate, the max, the min, and how much it has changed since the start of the period.”

Multi-year trend analysis for EUR/CHF

“I need to analyze the EUR/CHF ECB reference rate over the past 5 years — pull the full daily series with the average, high, low, and annualized volatility so I can chart the long-term trend.”

Technical details

Endpoint

POSThttps://api.vextorium.com/divisas-serie-pago?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need official ECB reference exchange rates (not market/interbank rates) for a specific currency against the euro over a historical window of days to years, and you want pre-computed statistics (volatility, high, low, average, change) alongside the raw daily series in a single call. Prefer this over a general ECB rates endpoint when you need the time series and summary statistics together rather than just the latest snapshot rate.

Side effects

Invalid or unsupported ISO currency code returns an error or empty result
Days parameter outside 5–1825 range may be rejected or clamped
Non-trading days (weekends/holidays) are omitted from the series, which can reduce the expected count
ECB does not publish rates for all world currencies; unsupported pairs return no data
Network or upstream ECB data source unavailability causes failure
