Akoya
APIs
Bank-owned, token-based open finance network that replaces screen scraping for US financial data

- On request
- Rated

The short version
- Only Asyncapi 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.; Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
- They diverge on capability: Akoya covers FDX standard APIs, Asyncapi covers API Specification.
- Prices and features above were last checked on 31 August 2026.

Akoya
- A wealth management platform that needs Fidelity brokerage holdings and tax lots, which cannot be scraped since Fidelity closed that route in October 2023not Asyncapi
- A tax preparation product retrieving tax forms and cost basis directly from the institution rather than asking users to upload PDFsnot Asyncapi
- A lender that needs a permissioning trail defensible under CFPB section 1033 rather than a credential-sharing arrangementnot Asyncapi
- A bank that wants to meet data sharing obligations through one network connection instead of building and policing its own developer interfacenot Asyncapi

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- Pricing is unpublished and usage based, which makes it difficult to compare against aggregator pricing during a build-versus-buy decision and forces a sales cycle before you can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.
Asyncapi
- Complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
- Keeping AsyncAPI documents up to date is challenging as systems evolve
- Tracing and debugging asynchronous operations is more difficult than synchronous request-response patterns

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.
Asyncapi: What is AsyncAPI used for?
AsyncAPI is an open-source specification for defining and documenting asynchronous APIs, message-driven systems, and event-driven architectures. It serves the same purpose for async APIs as OpenAPI does for REST APIs, providing standardized documentation, code generation, and tooling.
SourceAkoya: 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.
Asyncapi: Is AsyncAPI free to use?
Yes, AsyncAPI is completely free and open-source. It is hosted by the Linux Foundation and supported by community contributions and sponsorships from companies like Postman, IBM, IQVIA Technology, and Solace.
SourceAkoya: 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.
Asyncapi: What protocols and technologies does AsyncAPI support?
AsyncAPI supports multiple protocols and technologies including Kafka, RabbitMQ, MQTT, Socket.IO, AWS EventBridge, and others. It provides language support for JavaScript/TypeScript, Python, Java, Go, C#/.NET, Kotlin, and PHP.
SourceAkoya: Does it help with CFPB section 1033?
It is designed around it, providing tokenised permissioned access and consumer revocation rather than credential sharing.
Asyncapi: Does AsyncAPI have IDE support?
Yes, AsyncAPI has IDE extensions available for VSCode and IntelliJ, along with CLI utilities and GitHub Actions integration for developers.
