The short version

  • Only Swagger has a free tier, so it costs nothing to try first.
  • Each has a real cost: Swagger specific pricing details not published on main website; requires accessing pricing page or contacting sales; Token.io account to account payments carry no chargeback scheme, so merchants gain cost savings but consumers lose the dispute protection cards provide, which limits adoption in general retail.
  • They diverge on capability: Swagger covers API Specification, Token.io covers Payment initiation.
  • 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.

Swagger

  • Specific pricing details not published on main website; requires accessing pricing page or contacting sales

Token.io

  • Account to account payments carry no chargeback scheme, so merchants gain cost savings but consumers lose the dispute protection cards provide, which limits adoption in general retail.
  • Conversion depends on each bank's own authentication journey, and slow or broken bank redirects cost sales in ways the merchant cannot fix or even always diagnose.
  • Variable recurring payments beyond sweeping are still being rolled out unevenly across banks and markets, so a subscription use case may be supported at one bank and not another.
  • Token.io initiates payments rather than acting as acquirer of record, so merchants still need settlement, safeguarding and reconciliation arrangements elsewhere.
  • Coverage and feature parity vary by country, so a pan European rollout means different capabilities and different bank behaviour in each market rather than one uniform product.

Token.io: Does pay by bank remove card fees?

It removes interchange and scheme fees, so unit cost is normally far below card acceptance, particularly on high value payments.

Swagger: Does Swagger offer a free plan?

Yes, Swagger offers a free tier described as simple, useful, and easy to master for API client functionality. Exact feature details and limitations are not specified on the homepage.

Source
Token.io: What about chargebacks?

There are none. That is the cost saving and the consumer protection gap, which is why it suits bills, top ups and account funding more than retail.

Token.io: Is Token.io regulated?

Yes, it is an authorised third party provider under UK and European open banking rules, but it initiates payments rather than holding merchant funds as an acquirer.
