An open banking API lets an app read a customer’s bank data or start a bank payment with the customer’s consent, without handling bank logins itself. Choosing a provider affects your bank coverage, payment options, compliance load and cost per connected account. This guide compares ten widely used open banking API providers so you can match one to your product and region.
Quick answer
- US fintech apps, lenders and account verification: Plaid
- Pay by bank in the UK and Europe: TrueLayer
- Broad European data coverage: Tink
- API-first infrastructure in Europe: Yapily
- Clean, enriched data for banks and credit unions: MX
- Mortgage and lending verification: Finicity
- Bank-controlled data sharing in the US: Akoya
- Enterprise data aggregation: Envestnet Yodlee
- Multi-region coverage from one API: Salt Edge
- Merchants already on Stripe: Stripe Financial Connections
“Top” here means a strong fit for a defined need based on published features and public information. It is not a guarantee of performance for your business.
What an open banking API does
An open banking API connects your app to customer bank accounts through a licensed or authorized intermediary. It can return balances, transactions and account details (data access), or initiate a bank-to-bank payment (payment initiation). In Europe, PSD2 sets the rules. In the US, the picture is less settled. The CFPB’s Section 1033 rule was finalized in 2024 but is currently enjoined and being reconsidered, so US access still relies heavily on commercial agreements between banks and aggregators, increasingly using the FDX standard. Payment initiation also sits next to card acceptance, so it helps to understand how a payment gateway works before adding pay by bank.

Open banking API pricing models
- One-time fee: A charge when an account is first connected or verified. Plaid uses this for products such as Auth and Identity.
- Subscription: A recurring monthly fee per connected account for ongoing data such as transactions.
- Per-request: A flat or variable fee for each API call or report.
- Quote-based: Negotiated pricing with minimums, common with enterprise and bank-focused providers.
A low per-connection fee can still become expensive if you stack several products on every account, so model costs against your real usage.

How to choose the right open banking API provider
- Start with geography. US data needs and UK or European payments point to different providers. The European payment solutions guide is a useful companion if you sell in Europe.
- Decide between data and payments. Some providers do both, while others are data only.
- Check bank coverage for your users. Test the specific banks your customers use.
- Model total cost. Include product stacking, minimums and overage fees.
- Review regulatory fit. Confirm licensing for each market and watch how US rules develop.
- Plan for growth. Look at multi-country support and volume pricing.
Common mistakes
- Choosing on headline per-connection price alone
- Assuming one provider covers every bank you need
- Ignoring connection quality, uptime and reauthentication friction
- Overlooking consolidation risk when a provider is acquired
- Skipping a pilot before committing to an annual contract
Need to accept bank payments at checkout?
If your goal is collecting payments rather than reading data, compare how pay by bank fits alongside cards and wallets by reviewing payment gateway reviews.
Verdict
There is no single best open banking API provider. US-focused data products suit Plaid, MX or Finicity, European payments suit TrueLayer, Tink or Yapily, and bank-led networks suit Akoya. Shortlist two or three, run a pilot with your own banks and users, and compare total monthly cost.
