How this service works
Currency exchange rates (European Central Bank reference rates) for price conversion, invoicing and travel budgets. Latest or historical by date.
Output
A JSON object containing the base currency, the rate date (today or requested historical date), and a map of currency codes to their exchange rates relative to the base, plus a source attribution ('European Central Bank via Frankfurter').
Example use cases
Invoice conversion for freelancer
“I just finished a project and need to bill a client in EUR and GBP — can you pull today's ECB rates using USD as the base so I can calculate the correct amounts?”
Historical rate for accounting reconciliation
“I need the official ECB exchange rates for 2024-03-15, with USD as the base, to reconcile a payment we received from a European client that day.”
Travel budget currency planning
“I'm planning a trip to Japan and Europe — can you look up the current ECB rates for USD against JPY and EUR so I can estimate how much local currency I'll need?”
Technical details
Endpoint
GEThttps://agent-tools.jbarkules.workers.dev/v1/fx/rates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official, authoritative ECB reference rates for financial calculations, invoicing, compliance, or accounting — especially when a trusted institutional source (European Central Bank) is required. Prefer this over free-tier or crypto-exchange-based FX APIs when rate credibility and historical accuracy matter. Best suited for EUR-centric use cases or any scenario requiring standardized reference rates rather than live market bid/ask spreads.
Side effects
- Invalid base currency code returns an error or empty rates
- Future dates return no data (ECB rates are not forward-looking)
- Very old historical dates may not be available in the ECB dataset
- Unsupported symbol codes in the comma-separated symbols list may be silently omitted or cause an error
- Weekend/holiday dates may return rates from the last available business day
