Implementation Example

Request skeleton. The URL below is this API's documentation page, not a live endpoint — swap in the path you need from the provider's docs before running it.

const url = "https://github.com/fawazahmed0/currency-api";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

import requests

url = "https://github.com/fawazahmed0/currency-api"
headers = {}

response = requests.get(url, headers=headers, timeout=30)
response.raise_for_status()
data = response.json()
print(data)

curl https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/usd.json

What Can You Build?

// Convert USD to EUR
const response = await fetch(`https://github.com/fawazahmed0/currency-api#readme`);
const data = await response.json();
const rate = data.rates?.EUR || data.conversion_rate || data.EUR;
const amount = 100;
const converted = (amount * rate).toFixed(2);
console.log(`$${amount} USD = €${converted} EUR (rate: ${rate})`);

// Multi-currency conversion widget
const response = await fetch(`https://github.com/fawazahmed0/currency-api#readme`);
const data = await response.json();
const rates = data.rates || data;
const currencies = ['EUR', 'GBP', 'JPY', 'CAD'];
const usdAmount = 100;
currencies.forEach(cur => {
  const rate = rates[cur] || 0;
  console.log(`$${usdAmount} = ${(usdAmount * rate).toFixed(2)} ${cur}`);
});

// Fetch historical exchange rates
const response = await fetch(`https://github.com/fawazahmed0/currency-api#readme`);
const data = await response.json();
const rates = data.rates || data;
console.log('Exchange rates:', rates);
const pairs = Object.entries(rates).slice(0, 5);
pairs.forEach(([currency, rate]) => {
  console.log(`1 USD = ${rate} ${currency}`);
});

How This API Fails

We deliberately sent this API a broken request and recorded exactly what came back on 2026-08-10. Knowing the shape of an error before you hit it makes error handling much easier to write.

Couldn't find the requested file /v1/currencies/usd.json/apisscore-nonexistent-path in @fawazahmed0/currency-api.

Common Errors & Troubleshooting
