How this service works
Convert an amount between two currencies with synthesized bid/ask spread and effective rate. Query: ?from=USD&to=EUR&amount=100&spread_bps=50. Source: ECB via frankfurter (keyless).
Output
Returns the converted amount in the target currency, the base ECB exchange rate, and the effective rate after applying the synthesized bid/ask spread in basis points.
Example use cases
Convert payment amount to local currency
“I need to send 1500 GBP to a supplier in Japan — how much is that in JPY using ECB rates with a 40 basis point spread?”
Compare effective FX rates with spread
“What's the effective rate I'd actually get if I convert 10,000 CHF to USD with a 75 basis point bid/ask spread applied?”
Calculate invoice total in euros
“A client owes me 800 Canadian dollars — can you convert that to euros using ECB reference rates and include a 25 bps spread so I know the realistic amount I'd receive?”
