# get_supported_bank_names

> Read canonical bank names for a hosted fiat rail when the directory is available.

**Surface:** Hosted OAuth\
**Mutates state:** No

```json theme={null}
{ "rail": "VND" }
```

Pass the destination currency rail from the quote, not an instrument or
provider name. Use a matching canonical value in a bank-transfer recipient.
If the lookup is unavailable or the directory is empty, pass the user's bank
name to `create_recipient` and let Core validate or canonicalize it. Do not
require QR solely because directory lookup is unavailable.
