Lucas and Luna dissect a specific silent failure pattern in modern APIs: the 200 OK response that contains a business-level error. Using Stripe's idempotency keys and GitHub's merge conflict response as concrete examples, they explore why HTTP status codes alone are not enough for reliable integrations. The episode covers how Twilio's API design team built 'semantic error codes' into their v2 spec, what Postman learned from testing over 50,000 public APIs, and why a 2025 industry survey found that 40% of developers trust a 200 response less than a 4xx when something goes wrong. No jargon theatre — just one sharp angle on API trustworthiness.
