  title: Fintecture List Providers and Initiate Payment
  summary: Discover supported bank providers, then open a payment session and inspect its status.
  description: >-
    A merchant onboarding-to-checkout flow. It first reads the Fintecture
    Resources catalog of bank providers to confirm coverage and PIS rails for a
    country, then creates a PIS payment session (Immediate Transfer) via the
    Payment Initiation Services API, and finally reads back the created payment
    to surface its connect URL and lifecycle status. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI descriptions.
