description: >-
  Wayflyer's sandbox surface for the Embedded Finance (Hosted Capital) API — a
  full parallel environment at sandbox-api.wayflyer.com with production
  parity ("if their integration works correctly in the sandbox, their
  integration will work correctly in production") plus simulation endpoints
  for driving application lifecycle states without processing real
  transactions. Captured from the sandbox docs and the separately published
  Embedded Finance Sandbox OpenAPI. No magic test values (cards, IBANs) are
  published — state is driven via the simulation endpoints instead.
