The short version

  • Only Stainless has a free tier, so it costs nothing to try first.
  • 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.; Stainless starter and Pro plan prices are not published and require contacting the company.
  • They diverge on capability: Method Financial covers Identity-based account resolution, Stainless covers SDK generation.
  • Prices and features above were last checked on 31 August 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  • Pricing is unpublished and split across data and payment events, which makes unit economics hard to model before volume and easy to misjudge in a product where every application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.

Stainless

  • Starter and Pro plan prices are not published and require contacting the company.
  • The free plan caps APIs at 25 endpoints, which excludes larger production APIs.
  • Overage charges apply per SDK/endpoint/month once limits are exceeded, which can make costs unpredictable at scale.

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.

Stainless: Is there a free plan, and what are its limits?

Yes. The Free plan supports up to 5 generators, 5 seats, APIs with 25 or fewer endpoints, and 100 preview builds per month, with email support.

Source
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.

Stainless: Who owns the generated SDK code?

The generated SDK code is owned by the customer and published by Stainless under the Apache 2.0 license.

Source
Method Financial: What does it cost?

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

Stainless: What happens if I exceed my plan's endpoint limit?

Customers exceeding their endpoint limits are billed per SDK, per endpoint, per month for the overage.

Source
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.
