QUICK OVERVIEW

Three Sources, One Interface

Open API is the unified exit for CloudTrace capabilities. CH1 native SDK devices, CH2 vendor-cloud devices via BS-Hub, and CH3 generic IoT devices via BS-IoT all share one RESTful API for query, command and event subscription.

Hub Brings Devices In

BS-Hub onboards and translates vendor-cloud devices. Open API does not talk to vendor protocols directly.

IoT Connects Devices

BS-IoT connects generic IoT devices. Open API exposes IoT service calls through a unified interface.

PRODUCT VALUE

Use Platform Capabilities Like Internal Services

Developers, IT admins, and ecosystem partners each find their answers here.

Tenant Developers & Integrators

  • Scattered APIs, long integration, self-built signing
  • Multi-language teams lack unified wrappers
  • No online debugging or code samples
  • One unified interface and signing standard
  • Official SDKs in Java/Python/Go/Node.js/C#
  • Online debug + changelog cuts integration from weeks to days

Tenant Admins

  • Exposed capabilities are invisible
  • Loose key management with leak risk
  • Quota and usage are unclear
  • AK/SK lifecycle + IP allowlist
  • Call logs and usage stats in one screen
  • Per-tenant QPS throttling for controlled usage

ISV & Ecosystem Developers

  • Capability boundaries are unclear
  • Lack event-driven mechanisms
  • No monetization or distribution channel
  • Standard event subscriptions (9+2 Webhook types)
  • Clear capability declarations and limitation notices
  • Tiered plans to build industry apps quickly
KEY ADVANTAGES

USE CASES

Four Typical Integration Patterns

Starter

ERP/CRM Asset Sync

Robot assets are scattered and ledgers don't match

Sync CH1/CH2 devices into ERP/CRM via unified query API

Professional

Property Dispatch Linkage

Completed tasks or alerts can't auto-create work orders

Subscribe to task/alert events to auto-generate work orders

Professional

MES Production Automation

Robots can't联动 with elevators, doors or sensors

Use IoT service calls to automate the production line

Enterprise

ISV Industry Dashboard

No standard data exit, high custom dev cost

Build dashboards using logs and stats APIs for end customers
