Is it possible to create an MQTT API to serve as a third-party API for other developers?
<p>Is it possible to create an MQTT API service for being consumed by others? </p>

<p>If yes, how can I do that and would that be of any use?</p>

<p>If no, why? Maybe it is possible to set up an API using some other IoT-specific protocol (like CoAP or something else)?</p>

<p>I thought that it would be useful to persist the sensors' data and the data generated by other IoT devices in some cloud for being processed and analyzed.</p>
