How do you handle breaking changes from third-party APIs in production?

Recently worked on a project where our team used 10+ third-party APIs. Twice this year we got hit by silent breaking changes and found out only when users complained.

Curious how others handle this and whether a tool that monitors API contract changes and surfaces relevant changelog updates automatically would have saved you time.

- How do you currently stay ahead of breaking changes? - Have you built internal tooling for this? - Would this be a painkiller or a vitamin for your team?
