## What it is
API Star is a Python toolkit for working with OpenAPI and Swagger schemas, providing schema validation, static API documentation generation, and a dynamic client library for making API requests. Since version 0.6 it is framework-agnostic tooling rather than a web framework, usable standalone or integrated into other frameworks.

## Use cases
- validate openapi schema files
- generate api documentation from swagger spec
- make api requests from an openapi schema
- build static docs site for a rest api
- validate requests and responses against a schema
- preview api docs while editing schema

## When to choose
- you need to validate or lint OpenAPI/Swagger documents with contextual errors
- you want static, themeable API documentation generated from a schema
- you need a lightweight dynamic client driven by an OpenAPI spec

## When to avoid
- you want a full web framework or server - the server was removed after 0.5
- you need actively maintained tooling - the latest release is from 2022
- you need modern OpenAPI tooling with ongoing ecosystem support
