Go Sample Code: Real-time Currency Rates API

Here is an example that will retrieve current exchange rates for over 150 global currencies.

Go code:

            
package main

import (
    "encoding/json"
    "fmt"
    "net/http"
)

type Payload struct {
	Symbol   string
	Name     string
	Country  string
	Rate     string
	Code     string
	Credits  int
}

func main() {
    // Create the struct variable to store the decoded JSON response
    thePayload := Payload{}

    // Call the API
    // Can error check here too replacing underscore with 'err'
    response, _ := http.Get("https://api.interzoid.com/getcurrencyrate?license=
                YOURAPILICENSEKEY&symbol=GBP")

    if response.StatusCode != 200 {
        // Report any HTTP Errors
        fmt.Println("Error: ", response.Status)

    } else {
        // Decode the JSON and print a comma-delimited response,
        // one of many ways to format the response
        _ = json.NewDecoder(response.Body).Decode(&thePayload)

        fmt.Println(thePayload.Symbol + "," + thePayload.Name +
		"," + thePayload.Country +
		"," + thePayload.Rate)
    }
}
            

To execute from the command line:

            
> go run YOURFILENAME.go
            

Results:

            
GBP,Pound,Great Britain,0.767
