#!/bin/bash
# This script shows how Nexus can request histories from
# a particular time frame. Such request must succeed via
# two connection types: EBICS and x-libeufin-bank. EBICS
# ensures the fetching of fiat payments made to the regional
# currency authority, whereas x-libeufin-bank does it for
# the regional currency circuit. Note: the time-framed
# request is exceptional: it's used only after a complaint
# from a user where they didn't get their funds as expected.
