Usage Guide

Features

Paste an OpenAPI/Swagger JSON document to automatically parse and display API title, version, server URLs, and all endpoints with their paths, methods, parameters, request bodies, and response structures.

Steps

Paste OpenAPI JSON to auto-parse; click any endpoint in the list for details; use the top-right search box to fuzzy search by path or summary; click "Sample" to load a demo document.

Notes

Currently only JSON format OpenAPI 3.x and Swagger 2.0 documents are supported, YAML is not yet supported; all parsing is done locally in the browser, documents are not uploaded to any server.
