The short version

  • Each has a real cost: Method Financial institution coverage is uneven once you move beyond major card issuers, so a lender focused on auto or student loan servicers should test its own portfolio mix rather than trust the headline institution count.; Ozone API it provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • They diverge on capability: Method Financial covers Identity-based account resolution, Ozone API covers Multi-standard support.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Method Financial

  • Institution coverage is uneven once you move beyond major card issuers, so a lender focused on auto or student loan servicers should test its own portfolio mix rather than trust the headline institution count.
  • It reads liabilities, not cash flow, so a lender that also needs income and affordability evidence is running a second aggregator alongside it and paying twice for consumer connectivity.
  • Payoff quote accuracy and freshness are commercially load bearing, because a consolidation loan funded against a stale figure leaves a residual balance and a customer complaint, and the contractual position on that risk needs to be explicit.
  • Pricing is unpublished and split across data and payment events, which makes unit economics hard to model before volume and easy to misjudge in a product where every application triggers multiple calls.
  • Identity-based access without credentials depends on consumer consent capture being defensible, and any shift in US regulatory interpretation of permissioned data access lands directly on this model rather than on the edges of it.

Ozone API

  • It provides the API layer, not the core connectivity, so the bulk of the project is still integrating your own core banking systems and that cost is not in the licence.
  • Value is driven by regulatory obligation, so an institution not under a mandate struggles to build a business case for the spend.
  • It is a small UK vendor selling to large regulated institutions, which raises procurement and vendor viability questions during bank due diligence.
  • Premium API monetisation is a genuine capability but few banks have found real demand, so revenue projections used to justify the purchase often do not materialise.
  • Standards evolve continuously and each revision means a change programme in your own systems, even where Ozone absorbs the specification work at the API edge.

Answered from the vendors’ own pages

Method Financial: How is this different from Plaid?

Plaid connects to deposit accounts with credentials and returns transactions. Method resolves liabilities from verified identity without credentials and can pay those accounts directly. Most lenders use both.

Ozone API: Is this a competitor to Plaid or TrueLayer?

No, the opposite side. Ozone is bought by the bank exposing data; Plaid and TrueLayer consume it on behalf of third parties.

Method Financial: Do consumers have to log in to each card issuer?

No. That is the point of the product, and removing that step is what changes conversion in consolidation and refinancing flows.

Ozone API: Does it connect to my core banking system?

It provides the standards-compliant API surface and adapters, but connecting your core is an integration project you scope separately.

Method Financial: What does it cost?

Not published. It is quoted by volume and split across liability data, payoff quotes and payment execution.

Ozone API: Which standards does it support?

UK Open Banking, Berlin Group, FDX, Consumer Data Right and Gulf regional standards, among others, from one platform.

Method Financial: Can it actually pay off a credit card?

Yes, funds are sent directly to the identified card accounts, which is what makes balance transfer and consolidation products work without account numbers.
