Supported Rails
Human-readable rail catalog and rail request caveats.
The metadata endpoint returns the supported rail catalog. Availability can still depend on customer type, country, currency, verification status, and flow.

|---|---|
| Fiat bank transfer | ach, fedwire, sepa, pix, spei, pse, swift |
| Fiat card | card, apple_pay |

Customer Rail Requests
