  • Display token prices in local fiat currencies
  • Power fiat input mode in fund/withdraw flows
  • Build currency selectors with live exchange rates
  • Show USD-equivalent values in non-USD currencies

​
Request Parameters

​
Optional Fields

  • toCurrency (string): ISO 4217 currency code (e.g. "EUR", "GBP", "JPY"). Defaults to "USD" if omitted.

​
Response

​
ExchangeRate Object Structure

  • name (string): Full name of the currency (e.g. "Euro")
  • symbol (string): Currency symbol (e.g. "€")
  • value (number): Exchange rate value relative to vsCurrency
  • vsCurrency (string): The base currency (typically "USD")
  • currencyType (string): Currency type identifier

Examples

​
Get EUR Exchange Rate

const response = await fetch('https://trails-api.sequence.app/rpc/Trails/GetExchangeRate', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-Access-Key': 'YOUR_ACCESS_KEY'
  },
  body: JSON.stringify({ toCurrency: 'EUR' })
});

const { exchangeRate } = await response.json();

console.log(`1 USD = ${exchangeRate.value} ${exchangeRate.symbol}`);
// e.g. "1 USD = 0.92 €"

​
Convert a USD Amount

async function convertToLocal(usdAmount: number, currency: string): Promise<string> {
  const response = await fetch('https://trails-api.sequence.app/rpc/Trails/GetExchangeRate', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'X-Access-Key': 'YOUR_ACCESS_KEY'
    },
    body: JSON.stringify({ toCurrency: currency })
  });

  const { exchangeRate } = await response.json();
  const localAmount = usdAmount * exchangeRate.value;

  return `${exchangeRate.symbol}${localAmount.toFixed(2)}`;
}

const display = await convertToLocal(100, 'GBP');
console.log(display); // "£82.50"
