Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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.
