Ask HN: Outsourcing credit card data storage?

I'm currently developing a complex recurring payment system. Our payment gateway does not offer a "secure vault" service, and we will need to charge customers a variable amount each month. Therefore we will need to store customers' credit card details.

However, ideally I would like to avoid having to be compliant with PCI level D, so I'd like to find a company which:

* Will allow us to securely store customers' credit card details on their PCI-compliant servers.

* Allow us to retrieve one or all of the stored card details via their API at any time, so we can submit new payments using them.

I'm pretty new in the world of payment processing. Is there a company offering this kind of service?

(NB: I'm not looking for a full billing service like Spreedly or Chargify. I just want secure storage for credit card details, nothing more.)
