Bitfinger

Bitfinger.org is a lookup service for bitcoin addresses. It is based on Webfinger, a micro-format to describe human readable identifiers like account@host.org.

Instruction

The solution can be used in many ways, with CORS headers and DKIM signature provided. These instructions utilize Dropbox anid Gmail for a simple setup.

To publish your bitcoin address following the Webfinger standard you need to follow these steps:

1. Create a file

Create a file called webfinger.js in your Dropbox Public folder with this content:

{
  "subject": "acct:makingabetter@gmail.com",
  "links":
  [
    {
      "rel": "bitcoin",
      "href": "bitcoin:19xeDDxhahx4f32WtBbPwFMWBq28rrYVoh"
    }
  ]
}

make sure to replace email and bitcoin address in the example with yours.

2. Copy URL

Copy the public URL of this file. It should start like this 'https://dl.dropboxusercontent.com/...' and end with .js. Make sure it's not just the web link, but the actual file.

3. Send Email

Send an email from your Gmail account to fist@webfist.org with this content:

webfist = https://dl.dropboxusercontent.com/u/accountid/webfinger.js

Replace the link with the link from step 2.

4. Check

Check http://webfist.org/ with your Gmail address and see if you can get a positive response.

Check https://bitfinger.org and see if you can get the bitcoin address back as a QR code.
