How this service works
Use for a short euro exchange rate history: daily ECB euro foreign exchange reference rates of one currency against EUR for up to the last 30 days (ccy=USD, days=1..30), with min, max and percent change over the window and a stale flag. Source attribution in every reply. Reference rates for information only, not transaction rates. $0.002 USDC per call. Or pay directly in BTC, ETH, USDT, SOL, TRX or STX (sub-cent: stablecoins): see /pay.
Output
A JSON object containing the EUR base, the quoted currency, the requested day count, an array of {date, rate} data points, the minimum and maximum rates over the period, the percentage change from first to last point, a staleness flag, the source name ('ECB euro foreign exchange reference rates'), the source URL, and a note about publication timing (around 16:00 CET on TARGET working days).
Example use cases
FX trend analysis for EUR/USD
“Show me the EUR/USD exchange rate from the ECB every day for the past 14 days — I want to see the highs, lows, and the overall percentage change.”
Currency conversion research for EUR/GBP
“What have the official ECB EUR/GBP reference rates been over the last 7 days? I need the daily series to estimate conversion costs.”
Staleness check for live FX dashboard
“Grab the latest ECB euro rate data for EUR/JPY — just the last 2 days — and tell me whether the data is stale or current.”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/eu/fx/history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official ECB euro reference rates as a time series for research, analytics, or enrichment purposes — especially when you want the authoritative daily mid-market rate published by the European Central Bank rather than a real-time commercial feed. It is ideal for historical trend analysis, compliance documentation referencing official ECB rates, or enriching financial calculations with up to 30 days of daily EUR-based FX history. Not suitable for real-time trading rates or non-EUR base pairs.
Side effects
- Unsupported currency code returns an error or empty points array
- days parameter outside 1-30 range is rejected by schema validation
- ECB data not yet published for the current day causes stale=true flag
- Weekend or TARGET holiday gaps result in fewer data points than requested days
- Network or worker timeout returns a 5xx error
