What can you build with KeyServ?

KeyServ is a IoT API. Developers commonly use iot APIs for:

collecting and streaming sensor and device data
monitoring and controlling connected devices
building smart-home and industrial dashboards
processing device telemetry at scale
automating device provisioning and alerting

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. KeyServ is free to use, making it a low-risk choice to experiment with.
