Getting started with API Blueprint

All it really takes to describe an endpoint of your API is write something like this:

# GET /message
+ Response 200 (text/plain)
    
        Hello World!

in your favorite Markdown editor. Now you can share and discuss this API in your API repository and let GitHub to render the API documentation so others can see it.

Jump directly to the API Blueprint Tutorial or browse the interactive examples to learn more about the API Blueprint syntax.

Describing your API is only the start. The API Blueprint can be used by variety of tools from interactive documentation and code generators to API testing tools thanks to its machine-friendly face:

{
  "_version": "1.0",
  "metadata": {},
  "name": "",

    ...

It is the task of the native API Blueprint parser or one of its bindings to "translate" the API Blueprint Markdown representation into a machine friendly format – AST.
