Yes, But The API Says No

The classic API response contradiction that haunts my nightmares. Server returns HTTP 200 OK (everything's fine!) but then smugly delivers {"error": true} in the response body. It's like a waiter saying "Your meal is ready!" while handing you an empty plate with a note that says "actually we're out of food." Seven years of backend development and I'm still finding APIs that pull this nonsense. The worst part? Some senior dev is defending this somewhere right now as "technically correct."
