As a consumer, you can set up an alert when any of your API requests has a deprecation or sunset HTTP header. You'd know immediately if any of the APIs you depend on is about to be deactivated.

If they were competent enough to do that, they'd probably pay attention to updates sent via, say, email. Brownouts would make people notice, like "oh shit, $API doesn't work!"
