The short version
- Each has a real cost: Marqeta you still need a sponsor bank and a BIN, so the timeline and compliance burden of launching are set by a bank you must separately court and satisfy.; Salt Edge coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.
- They diverge on capability: Marqeta covers Just-in-time funding, Salt Edge covers Account information.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Marqeta
- You still need a sponsor bank and a BIN, so the timeline and compliance burden of launching are set by a bank you must separately court and satisfy.
- Pricing carries minimum monthly platform commitments, so a programme with modest card volume pays for capacity it never uses.
- Programme revenue depends heavily on interchange, which means regulated debit interchange caps and European interchange caps materially change the business case by market.
- Disputes, chargebacks and fraud losses sit with the programme, and teams that assumed the processor absorbed them discover a real operations headcount requirement.
- Just-in-time funding makes your own authorisation endpoint a hard availability dependency; if it is slow or down, cards decline at the point of sale.
Salt Edge
- Coverage outside regulated open banking markets is not all direct bank API, and connections that are not regulated interfaces break when a bank changes its systems, so a headline country count overstates the reliability you will actually experience.
- Pricing is not published and is usage-based, so two providers cannot be compared without running both sales processes, and cost grows with the connected user base rather than with revenue.
- Support and engineering are distributed across Eastern Europe and Canada, and buyers in other time zones report slower turnaround on connection-specific breakages than they get from a domestic provider.
- PSD2 consent rules require customers to reauthenticate periodically, and Salt Edge cannot change that, so any product depending on continuous data must design for consent expiry and the drop-off it causes.
- United States coverage is weaker than Plaid or Mastercard Open Banking, so a company with meaningful US volume ends up running two aggregators and normalising between them.

Answered from the vendors’ own pages
Marqeta: Do I need a sponsor bank?
Yes. Marqeta is an issuer processor, not a bank. Card programmes run on a sponsor bank BIN, and that bank approves and supervises your programme.
Salt Edge: Who owns Salt Edge?
It is independently owned, unlike Tink (Visa), Finicity (Mastercard) or Yodlee (Envestnet), which matters if your use case competes with the owner.
Marqeta: How does the pricing really work?
A minimum monthly platform fee plus per-transaction and per-active-card charges, offset by a negotiated share of interchange. The interchange split is the substance of the deal.
Salt Edge: Is all coverage direct bank API?
No. Inside PSD2 markets connections use regulated APIs; elsewhere coverage relies on direct connections whose reliability depends on the bank not changing its systems. Ask for a per-institution answer.
Marqeta: What is just-in-time funding?
Marqeta calls your endpoint at authorisation so you decide and fund each transaction, rather than pre-loading balances onto cards.
Salt Edge: Does it do payments as well as data?
Yes, payment initiation is supported in European markets where PSD2 applies.
Salt Edge: What does it cost?
Not published. Pricing is usage-based and quoted, though the sandbox is free.
