Bitcoin Price Extension

Bitcoin Price Extension

Hello everybody,
I have just developed an extension that gives you the bitcoin price.
This extension can be useful for projects that i-ntend to make conversions with the price of bitcoin or other similar projects.

---

How it works

It is super simple to use (it only contains two blocks).

---

We use this block to request to obtain the bitcoin price.

---

This block is used to obtain the bitcoin price.
With this block we can tell it to put the price in a "label", "button"...

---

The bitcoin price is in euros (or at least that in Spain) and I have not included in the extension the symbol €, if you want me to put the bitcoin price + € you will have to do it joining the texts.

---

Download the extension using this link (v1.0):

This extension was created thanks to the contribution of @Kumaraswamy in the post

How do I make an extension that retrieves the source code of a web page?

I have the demo extension code which works.

thank you for your contribution...
please remember to follow the naming conventions

Naming Conventions for Extension Developers

If you are developing an extension, then please follow the naming conventions, which is UpperCamelCase for the package name as well as for property, method and event names (i.e. the first letter should be a capital letter) and lowerCamelCase for parameter names, no underscores . Example [naming] What does UpperCamelCase mean? UpperCamelCase (part of CamelCase ) is a naming convention in which a name is formed of multiple words that are joined together as a single word with the first l…

the correct name for GetBTCprice would be GetBtcPrice

Taifun
PS: it would be not too difficult to get the same functionality just by using the web component...
let me suggest you to focus on extensions, which are not doable using available blocks...

Hi @Meulencv I've tried your extension and it doesn't give me any results.
My Blocks:

[Patryk_F]

In AppInventor works. It currently shows 47 360.82 euros.

[Meulencv]

Are you in kodular?

[Meulencv]

For me works

[Salman_Dev]

I think it not works with Kodular

[TIMAI2]

Then please discuss on Kodular community.

[Meulencv]

Ok
Thanks @Salman_Dev

[Salman_Dev]

oh no, I've tested it in the app Inventor too and it doesn't work.
I think the problem is because this link contains hCaptcha
https://www.coinbase.com/es/price?query=bitcoin
and the problem is also because you only take bitcoin number from website that may be problematic in some countries, and I've tried it with a VPN and it works.

[Salman_Dev]

Oops, I can make the same function without having to use your extension.

My Blocks :

And with the logic that I make above,
it produces results that are 100% same as the extension you made @Meulencv

Aia Project :
GetBitcoin.aia (2.2 KB)

[Meulencv]

Yes, I know to do this, but the extension is more easy to use😁

[Salman_Dev]

@Meulencv

but the extension is more easy to use😁

yeah you are right, but in my opinion you better not make extensions that can be made easily using the available blocks, so if you want to make an extension, it's better if you make an extension that cannot be made with the available blocks or can be made with the available blocks but difficult to do (requires more than 100 or 200 blocks to make it)
