How this service works
Official ECB reference exchange rates for about 35 currencies (USD, EUR, GBP, JPY, CNY, INR, AED, SAR and more) for today or any date since 1999, from any base currency, with optional amount conversion. Use to convert prices, invoices or salaries between currencies.
Output
Returns a JSON object containing the base currency, the date of the fixing (adjusted to the last business day if a weekend or holiday), and a map of target currency codes to their exchange rates (and optionally the converted amount if an amount was specified).
Example use cases
Invoice conversion for international client
“I need to send an invoice to a client in the UAE — can you convert 8500 USD to AED using today's official exchange rate?”
Historical salary comparison
“What was the exchange rate between GBP and INR on 2022-06-30? I want to know what 75000 GBP would have been worth in INR on that date.”
Multi-currency price display
“Get me the current ECB rates for USD, EUR, GBP, CNY, and JPY all relative to EUR as the base so I can display prices in multiple currencies on my site.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/finance/fx?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need official, authoritative ECB reference rates for fiat currency conversion — especially for financial documents like invoices, salaries, or accounting records where ECB rates are the regulatory standard. Choose this over crypto price feeds for fiat-only conversions. Use when historical rates back to 1999 are needed or when a specific date's rate is required.
Side effects
- Invalid currency code returns an error or omits the currency from results
- Dates before 1999 are out of range and will fail
- Weekend or holiday dates fall back to the previous ECB fixing day — agent should note the actual date returned
- Unsupported currencies not in the ECB ~35-currency basket will be missing from results
- Network timeouts possible as service runs on a shared Render instance
