Fallback mechanism #90

fawazahmed0 · 2024-03-05T10:49:02Z

Fallback URL:

https://{date}.currency-api.pages.dev/{apiVersion}/{endpoint}

Pseudo code:
For example, if you want to fetch eur:

Fetch https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/eur.min.json
If above url fails, then try fetching https://latest.currency-api.pages.dev/v1/currencies/eur.min.json
If above url fails, then try fetching https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/eur.json
If above url fails, then try fetching https://latest.currency-api.pages.dev/v1/currencies/eur.json

The text was updated successfully, but these errors were encountered:

bobaikato · 2024-03-05T20:27:57Z

Whats the difference between eur.min.json vs eur.json?

fawazahmed0 · 2024-03-06T07:50:12Z

eur.min.json has no white space to reduce file size

brother please help.. i am new to programing. just making currency converter.
you have migrated the files to github. I want to use this link https://cdn.jsdelivr.net/gh/fawazahmed0/currency-api@1/latest/currencies/eur/jpy.json in my code but i can't. so as per the given instructions i figured out a little bit and i was able to make this link https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/inr.json but at the last of this link i need usd/inr.json Plz help me out

I want to use this link https://cdn.jsdelivr.net/gh/fawazahmed0/currency-api@1/latest/currencies/eur/jpy.json in my code but i can't. so as per the given instructions i figured out a little bit and i was able to make this link https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/inr.json but at the last of this link i need usd/inr.json Plz help me out

@gaganpreetsharma000, have you seen the migration instruction? It's pretty clear.

By the url, https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/inr.json you are fetching data in the rate INR/XXX, where XXX is another currecy from the got JSON, e.g. USD. In that case, one INR costs 0.012070684 USD.

As you need usd/inr, you have to fetch data USD/XXX: https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/usd.json, where you'll get a cost of one USD in different currencies, and select the needed one from the received JSON, in your case INR.

Try

async function getUsdInrRate() {
    // This url will give you currencies UDS/XXX
    const url = 'https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/usd.min.json'

    // Fetch data and get INR rate
    const inr = await fetch(url)
        .then(response => response.json())
        .then(data => data['usd'].inr)

    console.log(inr)
}

getUsdInrRate()

You'll get current rate

Tip

Use min versions of the files to get reduced files (whitespaces deleted), and faster responses, I assume.
Instead of 'https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/usd.json'
Use 'https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/v1/currencies/usd.min.json'
I used the second one in the code

I've tried all the fallback URLs but I don't think they work when sent through a node environment. When I try the same on a browser they seem to work
