It actually works in our test API for anyone. Check it:

Make a card:

    $curl https://api.balancedpayments.com/cards \
      -u ak-test-2qEM0Znvd8LIVbZ01LbFHvHgab4fkNr3c: \
      -d name="Johannes Bach" \
      -d number=4342561111111118 \
      -d expiration_month=05 \
      -d expiration_year=2017

The 'credit' link in the response is that comes back is '/cards/CC2mEWYlYvod2E1w3TJHOiGh/credits'. So we push:

    $ curl https://api.balancedpayments.com/cards/CC2mEWYlYvod2E1w3TJHOiGh/credits \
      -u ak-test-2qEM0Znvd8LIVbZ01LbFHvHgab4fkNr3c: \
      -d amount=10000

We will turn it on _in production_ for people in the beta period. Some customers have already integrated it in test!

You're right.

Our API has been built, but we're giving private beta access to anyone that made prepayments via our crowdfunding campaign [1] first. Private beta will launch next week [2]. We want to make sure the performance (instant payouts & high coverage) is on par with our standards before a public release, which will happen later this summer.
