This question already has an answer here:

Are there any Bitcoin clients or services that support sending bitcoins to a HTTP(S) URL instead of having to enter a Bitcoin address directly? (e.g. for donations)


Webmasters could include their Bitcoin address in a link element in each page (same for the whole site or different for each page, e.g. to account which page generated which donation):

<link rel="payment" href="bitcoin:…" title="Donate bitcoins, if my article was of help to you">

The href attribute should contain the Bitcoin address, using the bitcoin URI scheme.

The rel attribute should have the value payment. It’s defined as:

RelPayment is a microformat for making exchanges of support (be it financial or otherwise) possible. By adding rel="payment" to a hyperlink a page indicates that the destination of that hyperlink provides a way to show or give support for the current page. For example to give financial support to the owner of the current page.

The (optional) title attribute could contain a small note, e.g. what the donations are used for, or who exactly would be the receiver etc.


Tools (Bitcoin clients/services, browser add-ons etc.) could extract the Bitcoin address by looking for a link with the link type payment whose URI uses the scheme bitcoin. If one enters a webpage URL that hasn’t linked a Bitcoin address, the tool should throw an error. For security reasons probably only link elements should be parsed (instead of a/area), otherwise e.g. commentators could include their own Bitcoin addresses.

    These things should probably be implemented by browsers, not by clients. – Tom van der Woerdt May 13 '13 at 11:10

    You could create a browser extension yourself that allows you to donate to the current page (when it supports it). – Steven Roose May 13 '13 at 19:23
  • @e-sushi: It’s not a duplicate. A Bitcoin URI scheme is for representing a Bitcoin address as URI, while this question is about using HTTP URIs to send Bitcoin (which could make use of a Bitcoin URI specified on the HTML page). – unor Oct 30 '17 at 16:35
  • @unor Woops, my bad… didn’t notice that what you’ve asked about was looking for something going the other way around. Removed my “dupe” comment accordingly. – e-sushi Oct 30 '17 at 18:11
  • @asterisk: My reply to e-sushi’s comment above is about the same question: I don’t think it’s a duplicate. – unor Oct 31 '17 at 2:34

The client Electrum seems to support something like that (using a different method): Aliases:

Aliases may be server names (e.g. ecdsa.org) or email-like addresses (e.g. john.doe@ecdsa.org)
The corresponding Bitcoin address is retrieved by the client, using a descriptor located at a canonical url.

Aliases may be entered in the Electrum client, or used in Bitcoin URIs […]

Yeah I think this feature is going to be awesome; I guess its already included in the HTML5 specs: https://html5.org/r/7850

If this worked similar to "mailto:" across all browsers & OSes, it could become ridiculously easy to accept payments through your website, maybe BitPay wouldn't be needed as long as native clients could pick up the slack & do currency conversion etc. Right now the user needs to exit your page and pull up their wallet to make a payment, which is a huge barrier.

Armory already supports donating with a syntax like this. The syntax is as follows:

bitcoin:1ArmoryXcfq7TnCSuZa9fQjRYwJ4bkRKfv?amount=1.0&label=Armory%20Developers&message=Donation%20to%20Armory

See https://bitcoinarmory.com/ for the reference of where I got this from, it's at the bottom of the page before the QR code.

That's just an http link where it is using bitcoin: as a prefix similar to how email links are setup, it has the bitcoin amount, the label, and the the address all pretty clearly labeled here.

    You haven't addressed the question, you've just re-stated bitcoin.stackexchange.com/questions/4987/bitcoin-url-scheme as already included and linked to in the question. – dchapes Nov 15 '13 at 17:22
  • OP is looking for services that support sending bitcoins to a HTTP(S) URL instead of having to enter a Bitcoin address directly, So, your answer is rather useless. – e-sushi Oct 30 '17 at 18:13
