Shameless plug, but Moov offers a single API for payments. The clearing house's RTP system will be supported shortly, and FedNow is coming soon after. Check out out here: https://moov.io/
Agreed. This is really strange from their pricing page:
>> Get started for free to test our APIs & unblock your development team. Talk to us about your transaction volume to get the best pricing with flexibility to grow.
You would think there would _at least_ be a ceiling price. Makes me wonder why they can't show _any_ pricing.
