  • They diverge on capability: Episode Six covers Tritium API platform, Swagger/OpenAPI covers OpenAPI Specification.

Where each one falls short

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

Episode Six

  • Deployment on premise or in a private tenancy means the institution carries infrastructure, upgrade and PCI scope work that a hosted processor would absorb.
  • Implementation runs to quarters and involves core banking, network certification and fraud system integration, so time to first card is far longer than with a self serve issuer processor.
  • Pricing is entirely bespoke and weighted to large programmes, which prices out fintechs and small issuers who would be better served by a hosted platform.
  • Being smaller than the incumbent processors, its network certifications and operational presence vary by region, so a global rollout can find gaps in specific markets.
  • The flexibility of six hundred APIs and a configurable product engine shifts design responsibility onto the buyer, and institutions without strong internal payments architects end up dependent on professional services.

Swagger/OpenAPI

  • The OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it
