Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Aiia
- It is now part of Mastercard rather than an independent company, so a business specifically wanting to avoid card network dependency in its banking infrastructure no longer gets that separation by choosing Aiia.
- Pricing is not published and requires engaging Mastercard's open finance sales process, which can be a heavier sales motion than dealing with a smaller independent open banking provider.
- Its strongest bank coverage remains concentrated in the Nordics and Northern Europe, so companies needing dense coverage in Southern or Eastern Europe should verify current bank connectivity before committing.
- Brand confusion is real: developer documentation, login portals and older case studies still reference "Aiia" while newer Mastercard material refers to "Mastercard Open Banking," and a company researching either name in isolation may miss half the relevant material.
- As with any open banking platform, reliability still depends on the consistency of the underlying banks' own APIs, which is a systemic industry issue rather than something Aiia specifically controls.
RapidAPI
- RapidAPI Enterprise Hub minimum seat requirement is 5 seats per the embedded pricing page configuration (SEATS_MINIMUM: 5).
- RapidAPI places a $0.50 USD temporary credit card authorization hold when subscribing, refunded only if no overage charges occur within 7 days.
