I'm already in love with the Custom Fields feature in Trello. Is there a way to get and set custom fields via the API?

I tried using the get field API call to get a field (on a board with a custom field defined called "MyCustomField"):

curl "https://api.trello.com/1/cards/57c473503a5ef0b76fddd0e5/MyCustomField?key=${TRELLO_API_KEY}&token=${TRELLO_OAUTH_TOKEN}"

to no avail.

The Custom Fields API from Trello is now officially available (announcement blog post here).

It allows users to manipulate both custom field items of boards and custom field item values on cards.
