The short version

  • Only Yapily has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Yapily production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.
  • They diverge on capability: Ozone API covers Multi-standard support, Yapily covers Unified open banking API.
  • 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.

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.

Yapily

  • Production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.
  • Consumer adoption of pay-by-bank still lags card payments, so merchants offering it as a checkout option typically see it used as a secondary rather than primary payment method.
  • Coverage depends on the banks in each country maintaining reliable open banking APIs, and inconsistent bank-side reliability across markets is a known category-wide weakness, not unique to Yapily but not solved by it either.
  • As infrastructure for both account data and payments, a company only needing one of those two capabilities is still evaluating a broader platform than it may need.
  • Regulatory dependence on PSD2 and UK open banking rules means the underlying legal framework, not just Yapily's product, could shift and affect what is possible on the platform.
