The short version

  • Only AWS API Gateway has a free tier, so it costs nothing to try first.
  • Each has a real cost: AWS API Gateway rEST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer; 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: AWS API Gateway covers REST APIs, 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.

AWS API Gateway

  • REST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer
  • Data transfer out is charged at $0.09 per GB on top of request pricing
  • WebSocket APIs bill connection minutes as well as messages, at $0.25 per million minutes
  • Private APIs avoid data transfer charges but incur AWS PrivateLink costs instead
  • The developer portal is $125 a month, with additional portal products at $12.50 each
  • The free tier lasts 12 months rather than being ongoing

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.
