Thanks. Something I missed is that the JSON is gonna be updated every 1 minute.

I've never tried netlify or vercel, I've been told that the 1 min updates are a problem in platforms like that. I'm an nginx kind of guy but I'm helping an org that has no budget whatsoever and I'm exploring options.

Yes, netlify typically does deployment by pushing to a git repo or uploading a zip, the update latency could take several seconds to a few minutes.

Another option is to use something like Firebase:

The free tier gives you 2M cloud functions per month, then $0.40 for each additional million cloud function invocations:

Update latency is a few hundred milliseconds which should be sufficient if you are sending updates every minute:

Just be aware that if your JSON payload is large, then you might consume all the egress bandwidth and it might end up costing more than you expect.

There are also alternative platforms which provide similar functionality (I have not used either of these though, so YMMV):

Thank you so much
