Require that any API or operation being retired is formally deprecated first, marked in the contract, and announced with a clear sunset date and migration guidance. I treat deprecation as a promise, not a surprise, because consumers built real businesses on your endpoints and they deserve a runway to move. Use the Deprecation and Sunset headers, flag it in the OpenAPI, and tell people in the changelog and in the portal so nobody finds out by getting an error. Graceful deprecation is one of the clearest signals that an API provider can be trusted over the long haul.
