# Demo: list proxies from the discovery API and show the egress IP each
|
|
# healthy one provides, by calling an IP-echo site through it.
|
|
#
|
|
# Usage:
|
|
# ./show-egress-ips.sh <BASE_URL> e.g. ./show-egress-ips.sh localhost:8090
|
|
#
|
|
# Optional environment:
|
|
# TOKEN bearer token for the discovery API (see docs/api.md)
|
|
# IP_ECHO_URL site that returns the caller's IP as JSON
|
|
# (default: https://api.ipify.org?format=json)
