OpenAPI Inspector
Validate and inspect OpenAPI/Swagger specs (JSON/YAML). See endpoints, security warnings, and export normalized JSON.
Think of an OpenAPI file as a “contract” for your API.
It describes what endpoints exist, what they accept (params/body), and what they return (responses).
openapi — Spec version
Example: "3.0.3". This is the OpenAPI standard version.
info — API identity
Human-friendly metadata: title, version, description, contact, license.
servers — Where the API lives
Base URLs (prod/staging/local). Tools use this for “Try it out”.
paths — Endpoints
Every URL path (/articles, /health) contains operations:
get, post, put, delete…
responses — What you return
Each operation lists HTTP codes (200, 401, 404) with descriptions and optional schemas.
components — Reusable blocks
Define schemas/security once; reuse via $ref.
Tip: Start with openapi, info, servers, paths. Add components later.
