Ever since I moved this blog to Netlify I wanted to add a badge to the repository’s README displaying the deploy status. The Shields.io service doesn’t support Netlify badges yet, but luckily I found out that you can build dynamic badges by querying structured data from any public URL.

After digging into the Netlify REST API, I managed to make a badge that fetches all deploys for my site and extracts the status of the last deploy:

[![Deploy status](https://img.shields.io/badge/dynamic/json.svg?url=https://api.netlify.com/api/v1/sites/rbardini.com/deploys&label=deploy&query=$[0].state&colorB=blue)](https://app.netlify.com/sites/rbardini/deploys)

Which looks like this:

One shortcoming is that you cannot set a different color depending on the status, that’s why I’m using a “neutral” blue background here. Also, I assume deploy logs must be public for the link (and possibly the badge itself) to work.
