They all have JS and REST-APIs and a lot more:
Although Recurly could be technically used in Europe, it generates invalid invoices (at least here in Spain).
We are switching away from it, and personally, I do not recommend it anymore.
After hearing additional requirements from dmarinoc and a few other merchants located in Spain, we have since implemented a solution for merchants using VAT.
Diego - I'll follow up with you directly about the changes :)

The specific issue with Recurly that we had is that they silently changed their platform to perform VIES validation on all VAT numbers. While this makes sense for transactions with entities from outside of the merchant's country, validating VAT numbers for German-to-German or Spanish-to-Spanish transactions is silly. Not only do such transactions always get charged VAT, but it's possible that a given string is a valid VAT number and yet is not present in VIES. Since you will pay (and therefore charge the customer) VAT for same-country transactions anyway, you don't care if the number that the customer provided is valid according to VIES.
This change has cost us a little wave of support tickets and an ugly workaround, in preparation for moving off Recurly.
I firmly believe that a company that gets online recurring payments right in Europe will become a money-printing machine in no time.
1. Recurly is right to add VIES validation for out of country transactions.
2. They shall not implement this feature for in country transactions.
German customers who buy in a german webshop have to pay VAT and then claim it back later in their tax return, because the german tax authorities don't allow that exemption beforehand.
In bad circumstances you don't want to lose all your payment infrastructure e.g. if paymill or stripe go out of business/have issues. That's why dealing with 2 parties may look odd but in the end it is worth the effort.
If you have problems paying the 50-100$ monthly fee, then your business is the problem. Not your payment partner.
(WireCard is a profitable, public credit-card processing bank, the chances that they go out of business is much lower than VC driven payment startups. See http://www.wirecard.com/investor-relations/ for details. They do CC-payments for Deutsche Telekom and Lufthansa. >11 Billion Euro/year)
Why should a scrappy startup pay an extra 50-100$ when it doesn't have to?
Why should a scrappy startup deal with the horrible paperwork of payment gateways on top of the horrible integration, when it doesn't have to?
You make no sense.
