Use [Google Apps Script][1] to create a web service, plop this in, and deploy.
You will need to authorize permissions and allow "Anyone" to access the API.
(Nothing sensitive is served by this app, obviously; it's just pulling poe.ninja
data. Your LED ticker needs to be able to access it, though.)

To hook it up to your LED ticker, go to its settings page, enable Custom API,
and enter the following values:

* ensure https is checked
* host: ``script.google.com``
* path: ``/macros/s/xxx/exec``

Replace the ``xxx`` in the path field with your deployment ID from Google Apps 
Script.

Currently, only two pages of data are shown, with room for 3 lines of items.
You can tweak the top of the file to change what's displayed without having to
rewrite/refactor any code.

Follow the instructions at [LEDTickers][2] if you want to make any changes
involving the response data.
