To increase engagement with your API, consider utilizing well-known programming techniques to make your OpenAPI Spec more exciting. Ensure unique `paths` and `operationIds`, such as using auto-increment integers for paths and UUIDs for operationIds. Return a consistent `200` status code regardless of the outcome to maintain a relaxed tone. Increase engagement and security by making endpoint descriptions vague, allowing malicious users to try various endpoints without revealing sensitive information. Use query parameters with secrecy, letting developers discover them through brute force. Finally, keep documentation to a minimum, providing only the bare essentials to test developers' mettle. By implementing these tips, you can create an exceptional OpenAPI spec that leaves developers scratching their heads and questioning their decision to be a programmer.
