The short version

  • Only Swagger/OpenAPI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Akoya coverage reaches several thousand institutions but does not match aggregators that can still scrape, so applications needing the long tail of small credit unions will run a second data provider alongside it.; Swagger/OpenAPI the OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it
  • They diverge on capability: Akoya covers FDX standard APIs, Swagger/OpenAPI covers OpenAPI Specification.
  • 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.

Akoya

  • Coverage reaches several thousand institutions but does not match aggregators that can still scrape, so applications needing the long tail of small credit unions will run a second data provider alongside it.
  • The network is owned by large banks, so roadmap and coverage priorities reflect owner interests rather than those of the fintechs consuming the data, and a recipient has no leverage over which institutions are added next.
  • Data availability is decided institution by institution, meaning a bank may expose balances but not transactions or investments, and recipients must verify field-level coverage per institution rather than assume the FDX model is fully populated.
  • Pricing is unpublished and usage based, which makes it difficult to compare against aggregator pricing during a build-versus-buy decision and forces a sales cycle before you can model cost.
  • The token model requires the institution to have implemented its side, so newly onboarded institutions arrive on the institution timetable, not yours, and a launch dependent on a specific bank can slip badly.

Swagger/OpenAPI

  • The OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it

Answered from the vendors’ own pages

Akoya: Who owns Akoya?

A group of large US banks. It was spun out of Fidelity, which is why Fidelity data access runs through it.

Swagger/OpenAPI: Is Swagger UI free to use?

Swagger UI is an open source tool with source code publicly available on GitHub at no cost. It is one of thousands of free open source projects in the Swagger ecosystem.

Source
Akoya: Is Akoya screen scraping?

No. It uses FDX standard APIs with OpenID Connect tokens, so credentials are never shared with or stored by the data recipient.

Swagger/OpenAPI: What commercial Swagger products are available beyond the open source tools?

Swagger offers Swagger for Teams for streamlined API workflow with interactive editors and hosted documentation, and Swagger Enterprise for organizations needing secure on-premise or cloud-based environments. Specific pricing requires contacting sales.

Source
Akoya: Can we use Akoya alone instead of an aggregator?

Usually not. Its investment and large-institution coverage is excellent, but the long tail of smaller institutions is thinner, so most teams run both.

Swagger/OpenAPI: Are there commercial versions that build on the open source Swagger tools?

Yes, commercial Swagger products integrate the core functionality of Swagger open source tools (Editor, UI, and Codegen) with advanced capabilities for team collaboration, standards enforcement, and enterprise features.

Source
Akoya: Does it help with CFPB section 1033?

It is designed around it, providing tokenised permissioned access and consumer revocation rather than credential sharing.

Swagger/OpenAPI: Is there a trial available for Swagger commercial products?

A Start Trial call-to-action is available on the Swagger website, but specific trial duration and terms are not disclosed on the product pages.
