Embedding my currently playing song in my Bluesky description

I've been thinking about adding last.fm integration to my site for a while now, but I've never been able to fit it with the style. It's really just not a great thing for my website, because most of my online "personality" is on bsky(1), so I decided to put it on my bsky profile.

In the first iteration, I polled the last.fm API every 90 seconds with pylast(2), and updated the bio with the data I got from that. This solution was *fine* but something about it grossed me out (3). It's by far the least optimal way this could've been implemented and I simply could not let it stand.

In the next (and current) iteration, I decided to replace the last.fm monitoring with a simple webhook that would trigger from my phone whenever the song I was playing changed. To implement this, I decided to write a tiny flask server that would accept a post request with an API key (because I have this webhook exposed to the internet), artist name and track title.

@app.route('/now_playing', methods=['POST'])
def lastfm_endpoint():
    provided_api_key = request.args.get('api_key')

    if provided_api_key == api_key:
        artist = request.args.get('artist')
        track = request.args.get('track')
        update_track(artist, track)
        return "Success", 200
    else:
        return "Unauthorized", 401

That flask server calls the update_track function, which passes formats the data into "{artist} - {track}" and updates my bio with it using the atproto python library.

I have the whole thing sitting on my server, running at about 231 MiB RAM usage, so you could run this just about anywhere for cheap/free (or rewrite it in a more performant language).

To actually get the data from my phone to the webhook, I use MacroDroid. I looked in to Tasker and Automate, but they were too complex for what I needed. I have a simple macro that, when my media changes, checks if it's from one of the apps that I scrobble from with Pano Scrobbler, and if so sends the track to my webhook.

You can see it in action on my bluesky profile (4), and the source on codeberg (5)
