## RunKit Endpoint

https://runkit.com/home#endpoint

If you are not familiar with RunKit endpoint, [this guide](https://runkit.com/docs/endpoint) would help.

## Use Badgen with RunKit Endpoint

1. Create a RunKit notebook (e.g. https://runkit.com/amio/cal-badge), which gives you an endpoint:

    \`\`\`
    https://runkit.io/amio/cal-badge/branches/master
    \`\`\`

  it returns a JSON like:

    \`\`\`
    {
      "subject": "2019",
      "status": "6-1",
      "color": "blue"
    }
    \`\`\`

3. Construct badgen url using \`owner\` and \`notebook\` params:

    \`\`\`
    https://badgen.net/runkit/amio/cal-badge
    \`\`\`

  That's it:

  ![](/runkit/amio/cal-badge)

Furthermore, you can append arbitrary path args (e.g. \`/Asia/Shanghai\`) to the end of badgen url, Badgen will request RunKit endpoint with that. This badge:

\`\`\`
https://badgen.net/runkit/amio/cal-badge/Asia/Shanghai
\`\`\`

![](/runkit/amio/cal-badge/Asia/Shanghai)

represents data from:

\`\`\`
https://runkit.io/amio/cal-badge/branches/master/Asia/Shanghai
\`\`\`
