OpenAPI/Swagger Generator

Builds an OpenAPI 3.0.0 spec as pretty-printed JSON from API metadata (title, version, description, base URL) and a list of endpoints. Each endpoint carries an HTTP method, path, summary, parameters (query/path/header/cookie), optional request body, and response map; the output is emitted on the Preview tab with a copy button.

1. On the Info tab, fill Title, Version, Description, and Base URL (used as servers[0].url). 2. On the Endpoints tab, click Add to create a new endpoint card. 3. Click a card to open the Edit Endpoint form and set Path, Method (GET/POST/PUT/DELETE/PATCH), Summary, and Description. 4. Open the Preview tab to read the live JSON and click Copy.

Endpoints are grouped under paths by their path string. Each operation is keyed by the lowercase method (get, post, put, delete, patch) under its path item. Parameters become {name, in, schema:{type}, required, description} entries. When a request body is present it is emitted as content keyed by its content type with a generic object schema. The responses object is emitted verbatim from your response map.
