Description, as the server wrote it:

```untrusted-server-text
Ranks US banks from lowest to highest published fee for one kind of wire (outgoing or incoming, domestic or international, in dollars or foreign currency), for personal or business accounts.

Personal accounts cover 17 banks and credit unions; business accounts cover 9 banks.

Same-day wire cutoff times as each bank publishes them (latest first, Eastern time used for sorting), the Fedwire Funds Service operating hours, and the 2026 Federal Reserve holidays. Pass a date to learn whether it is a Fedwire business day and, if not, the next one. Pass a bank to get only its cutoffs.
```
