Generates Markdown suitable for a README file from a local openapi.json file.

I still plan to add more features to this tool, but it is already useful for generating basic API documentation in Markdown from an OpenAPI schema.

This tool can be installed via uv, poetry or pip depending on your needs:

This tool is usually only needed during development, so it is recommended to install it as a development dependency.

uv:

uv add --dev openapi-readme

Poetry:

poetry add openapi-readme --group dev

Or Pip:

pip install openapi-readme

This will install the openapi-readme command line tool.

openapi-readme [OPTIONS]

Run this in the same directory as your openapi.json file. By default the Markdown output will be printed to the console, but you can redirect it out to a file too.

The particular styling of the generated Markdown is currently hardcoded, though plans are afoot to implement some sort of themeing.

• --route-level INTEGER: Number of heading levels to use. [default: 4]
• --inject / --no-inject: Inject generated output into a README file. [default: False]
• --help: Show this message and exit.

Specify the heading level for each Route in the generated documentation. This defaults to 4 if not specified, ie:

#### **`GET`** _/user/list_

Injects the new Markdown directly into a README.md file in the current directory, if it is found. You need to add the placeholder comment <!-- openapi-schema --> to your markdown where you want it to be injected:

This is some preceeding text

### API Schema description
<!-- openapi-schema -->

### Next section
The document continues unaffected after the injection.

Existing (previously injected) Schemas will be replaced by this new data.

Future improvement plans

• Take more info from the openapi.json file
