Developer Toolkit

Everything you need to ship.

01

MQTT API

Publish and subscribe over MQTT to control nodes, query status, and react to real-time events.

MQTTJSONPub/Sub
02

WebSocket

Subscribe to a real-time bidirectional event stream — device state, mesh events, system alerts.

ws://Real-timeMultiplexed
03

Developer Sandbox

Isolated Edge OS instance for local testing. No hardware needed — full API parity.

LocalhostNo HardwareDocker
04

SDK Libraries

TypeScript, Python, and Go client libraries with complete type coverage and auto-generated docs.

TypeScriptPythonGo
05

AI Extension API

Hook into the Edge AI runtime. Register model endpoints, run local inference, get sub-20ms results.

LocalONNX< 20ms
06

Webhook Outbound

Push device events, automation triggers, and system alerts to any external HTTP endpoint.

HTTP POSTHMAC SignedRetry Logic
100% Local
All API calls resolve on-device. Zero cloud round-trips for real-time commands.
No Rate Limits
Run your full test suite against the sandbox without worrying about throttling.
Offline-first
Your code keeps working even when the internet is down. Always.
