how this works

One call, two providers in rotation.

This page calls /v1/public/btc/rates, which asks the chainkit SDK for every supported fiat rate in one shot. Behind the scenes mempool and CoinGecko take turns — whichever is healthiest answers, the other backs it up. The multiplication happens in your browser.

The lookup above is a real call to chainkit's public API. Here's the same request as curl, in Go via the SDK, and the raw JSON response — everything you need to wire it into your own app.

$ curl 
curl -sS '/v1/public/btc/rates'
client.go 
rates, err := provider.GetExchangeRates(ctx, types.CoinTickerBTC)
if err != nil {
    log.Fatal(err)
}
for _, r := range rates {
    fmt.Printf("BTC → %s  %s\n", r.Currency, r.Rate.Text('f', 2))
}
