How much data, I think it depends, I've used MQTT some time ago, to receive a map of numbers every second.

There is only a small amount of data.

There isn't enough information here to answer. Both of them can easily download data every 3 seconds. Which one is "better" depends on many other factors.

Does the Apiprovider provide an MqTT-Broker too? Usually they do not.

It sounds the data provider is like a webserver, perhaps websocket is an option.

If you create both ends of the communication (I mean both the API and the client), and If I were you, I would prefer MQTT which is more light-weighted. If you don't, and you just consume the API, then as it is already said in this thread it depends on the API plus the latency of the server. And you might also consider some policies by several ISPs / Cloud providers that tend to ban IPs with lots of HTTP requests.

If you need real-time data, then mqtt is the best way
No need of timer, no need of manual polling

"On my server, I use Node.js with MQTT to fetch data from an external site every 5 seconds. The Node.js process is running under PM2. My publisher app connects to the MQTT broker. When many users connect to the publisher app, is it possible for the server to encounter errors?"
