The short version

  • Each has a real cost: Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature; Enable Banking production pricing is quoted per connected account and call volume with no published rate card, so a free proof of concept gives you no idea of cost at scale.
  • They diverge on capability: Asyncapi covers API Specification, Enable Banking covers European bank coverage.
  • 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.

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

Enable Banking

  • Production pricing is quoted per connected account and call volume with no published rate card, so a free proof of concept gives you no idea of cost at scale.
  • Coverage is European, which rules it out as a single supplier for anyone needing UK plus North American bank data as well.
  • Operating as an agent under the Enable Banking licence means your regulatory permission depends on another company remaining authorised and willing to sponsor you.
  • Bank API quality varies widely across Europe, and outages or degraded endpoints at individual institutions surface as failures in your own product.
  • It is a small Finnish company selling into regulated financial services, so enterprise procurement and vendor resilience reviews are a recurring obstacle.
