## About

The API documentation tool that creates interactive REST API documentation and developer portals in minutes. Auto-generate from OpenAPI & Swagger specs—no coding required.

## Overview

ApiNotes is an API documentation tool that generates interactive REST API documentation and developer portals from OpenAPI & Swagger specs in minutes. Developers can drop in an OpenAPI spec, choose a public URL, and publish docs without complex setup.

The tool supports OpenAPI 3.1, OpenAPI 3.0, and Swagger 2.0, and includes live API testing directly in the documentation. ApiNotes also provides an OpenAPI Validator and a Spec Diff Tool, plus options like auto-sync so documentation stays aligned with the latest spec as APIs evolve.

## Key features

- Choose a public documentation URL (apinotes.io) and publish quickly.
- Upload an OpenAPI spec (OpenAPI & Swagger) to auto-generate interactive REST API docs.
- Live API testing built into the docs, reducing the need for separate tools like Postman.
- Auto-sync updates so published documentation reflects changes to the API spec.
- OpenAPI Validator and Spec Diff Tool for validating and comparing spec changes.
- Mock API server for testing documentation flows without setting up an external environment.

## Use cases

- A developer with an existing OpenAPI/Swagger spec needs a public developer portal and interactive docs; ApiNotes publishes the portal and includes an API explorer for testing endpoints.
- A team iterating on an API wants documentation to stay accurate; they upload or update the spec and rely on auto-sync so the published docs reflect changes automatically.
- A developer preparing a release uses an OpenAPI Validator and Spec Diff Tool to check spec issues and review differences before publishing updated documentation.

## Who it's for

ApiNotes is designed for backend and API developers who already maintain OpenAPI/Swagger specs and want interactive documentation without building a custom portal. It also fits small teams that need documentation updates to track API changes with minimal maintenance.

## How it works

1. **Pick a documentation URL** — Choose a public URL on apinotes.io where the documentation will be published.
2. **Add the OpenAPI spec** — Upload or paste an OpenAPI/Swagger spec to generate the interactive REST API docs.
3. **Publish and test endpoints** — Use the built-in API explorer to test endpoints and verify the published documentation.

### Can the documentation stay updated when the API spec changes?

Yes. ApiNotes includes auto-sync so the published docs update automatically based on the updated spec.

### Is interactive testing available inside the documentation?
