Basic exchange rate implementation:

package main

import (
  "context"
  "log"

  "github.com/tonicpow/go-bsvrates"
)

func main() {

  // Create a new client (all default providers)
  client := bsvrates.NewClient(nil, nil)

  // Get rates
  rate, provider, _ := client.GetRate(context.Background(), bsvrates.CurrencyDollars)
  log.Printf("found rate: %v %s from provider: %s", rate, bsvrates.CurrencyToName(bsvrates.CurrencyDollars), provider.Name())
}

Basic price conversion implementation:

package main

import (
    "context"
    "log"

	"github.com/tonicpow/go-bsvrates"
)

func main() {

	// Create a new client (all default providers)
	client := bsvrates.NewClient(nil, nil)
    
	// Get a conversion from $ to Sats
	satoshis, provider, _ := client.GetConversion(context.Background(),bsvrates.CurrencyDollars, 0.01)
	log.Printf("0.01 USD = satoshis: %d from provider: %s", satoshis, provider.Name())
}
