Currency Conversion

There's no dedicated /convert endpoint. Fetch the rate and do the math client-side.

Recipe

async function convert(base, quote, amount) {
  const api = "https://api.currency.uwuapps.org";
  const res = await fetch(`${api}/v2/rate/${base}/${quote}`);
  const data = await res.json();
  return (amount * data.rate).toFixed(2);
}

convert("EUR", "USD", 10).then(result => console.log(`10 EUR = ${result} USD`));

Try it

Uses the same Single Pair Rate endpoint under the hood.

Rounding and precision

Rates are returned as full-precision floats, so round only at display time. If you're chaining conversions (e.g. USD → EUR → JPY), convert through the raw rate at each step rather than rounding intermediate amounts, or small errors compound.

Doing it server-side instead

The same recipe works from any backend language: fetch /v2/rate/{base}/{quote} with your HTTP client of choice and multiply. Nothing about it is browser-specific; the fetch example above is just the shortest way to show it.
