The possibility of an internet resource disappearing exists regardless of the resource type. Running an API Forwarder that could act as a common target for all your APIs might work. Give it the request, and it passes it on, records success, optionally sends a notification if an endpoint that previously succeeded is now failing. Add a fancy feature of redirection with format changing to handle replacing dead APIs with new ones transparently. If anybody makes one of these, they should totally make it a free public API. I'd use it, and I'm not certain if that would just be ironically.
