Launch Week III Day 5 introduced OpenAPI automations that seamlessly autogenerate API Reference documentation from OpenAPI specs, eliminating manual labor when APIs change. Users can now add an 'openapi' field to tabs or anchors in mint.json to automatically populate API Playground pages, supporting both local files and hosted URLs for real-time documentation updates.
Launch Week Day 5 brings OpenAPI automations to your documentation 🤖.
When you're constantly shipping changes to your API, it's important to reflect those changes in your documentation ASAP.
Our revamped setup makes autogenerating your API Reference docs seamless, removing the need for any manual labor to reflect changes in production
Getting Started
To auto-populate your API Playground pages, you can now add an openapi field to an object in the tabs or anchors arrays in the mint.json.
Example with Anchors:
{ Â "anchors": [ Â Â { Â Â Â "name": "API Reference", Â Â Â "openapi": "/path/to/openapi.json", Â Â Â "url": "api-reference", Â Â Â "icon": "square-terminal" Â Â } Â ] }
![]()
Example with Tabs:
{ Â "tabs": [ Â Â { Â Â Â "name": "API Reference", Â Â Â "openapi": "/path/to/openapi.json", Â Â Â "url": "api-reference" Â Â } Â ] }
![]()
We also support this functionality for OpenAPI Specs hosted at a URL. For example:
{ Â "tabs": [ Â Â { Â Â Â "name": "API Reference", Â Â Â "url": "api-reference", Â Â Â "openapi": "https://petstore3.swagger.io/api/v3/openapi.json" Â Â } Â ] }
Next Steps
Try out the feature yourself by updating your CLI:
**`npm i mintlify@latest -g
`**
And adding the following code to your mint.json:
{ Â "tabs": [ Â Â { Â Â Â "name": "API Reference", Â Â Â "url": "api-reference", Â Â Â "openapi": "https://petstore3.swagger.io/api/v3/openapi.json" Â Â } Â ] }

Docs as an abstraction layer for coding agents
A large engineering org ran controlled experiments to measure how structured Mintlify docs affect agent performance on massive codebases. The results: 64% more precise, 39% more discoverable, half the tokens, 1.5x faster.
