Currency Conversion Formula

To convert 100 USD → PKR:

const base = await fetch('https://cdn.jsdelivr.net/npm/@irfanokr/currency-api@latest/v1/currencies/usd.json')
  .then(r => r.json());

const pkrRate = base.usd.pkr;       // e.g. 278.50
const result  = 100 * pkrRate;      // 27850 PKR

To convert PKR → USD (or any pair):

const base = await fetch('https://cdn.jsdelivr.net/npm/@irfanokr/currency-api@latest/v1/currencies/pkr.json')
  .then(r => r.json());

const usdRate = base.pkr.usd;       // e.g. 0.003590
const result  = 50000 * usdRate;    // 179.5 USD

Use in Your Project

JavaScript / Node.js

async function convert(amount, from, to) {
  const base = from.toLowerCase();
  const target = to.toLowerCase();
  const url = `https://cdn.jsdelivr.net/gh/irfanokr/currency-api@main/v1/currencies/${base}.min.json`;
  const data = await fetch(url).then(r => r.json());
  return amount * data[base][target];
}

// 100 USD → PKR
convert(100, 'usd', 'pkr').then(console.log);   // ~27850

// 50000 PKR → USD
convert(50000, 'pkr', 'usd').then(console.log);  // ~179.1

// SAR → PKR (remittance)
convert(1000, 'sar', 'pkr').then(console.log);   // ~7427

Python

import urllib.request, json

BASE = "https://cdn.jsdelivr.net/gh/irfanokr/currency-api@main/v1/currencies"

def convert(amount, from_currency, to_currency):
    url = f"{BASE}/{from_currency.lower()}.min.json"
    with urllib.request.urlopen(url) as r:
        data = json.loads(r.read())
    return amount * data[from_currency.lower()][to_currency.lower()]

print(convert(100, "usd", "pkr"))   # ~27850.0
print(convert(1000, "sar", "pkr"))  # ~7427.0

PHP

define('CURRENCY_API', 'https://cdn.jsdelivr.net/gh/irfanokr/currency-api@main/v1/currencies');

function convert($amount, $from, $to) {
    $data = json_decode(file_get_contents(CURRENCY_API . "/{$from}.min.json"), true);
    return $amount * $data[$from][$to];
}

echo convert(100, 'usd', 'pkr');   // ~27850
echo convert(1000, 'sar', 'pkr');  // ~7427

How It Works

1. GitHub Actions runs daily at midnight UTC
2. Python script fetches rates from multiple free data sources
3. Generates one JSON file per base currency (170+ files)
4. Publishes as an npm package (@irfanokr/currency-api)
5. jsDelivr CDN serves the files globally — no server needed, ever

Zero cost. Zero maintenance. Open source.
