STD/SLL API questions

How do I get the STD/SLL exchange rate from an API?

Send one GET request to https://api.fxfeed.io/v2/latest?api_key=YOUR_API_KEY&base=STD&currencies=SLL, replacing YOUR_API_KEY with your own key. The JSON response carries the date and the latest STD/SLL rate in rates.SLL.

How far back does STD/SLL historical data go?

Daily STD/SLL rates are available from 2024-08-24. Request one day with the /historical endpoint and a date, or a range of days with /timeseries.

Is there a free STD/SLL exchange rate API?

Yes. The free plan includes 1,000 requests a month, with no credit card required; paid plans raise the limit.
