Particle Cloud API
IoT platform API for managing Particle-powered cellular, Wi-Fi, and Bluetooth devices with remote function calls, event publishing, and OTA firmware updates.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
OAuth2 with device/user scopes. OAuth access tokens with TTLs. TLS for device communication. Device-level product keys. Particle's cloud manages device authentication.
⚡ Reliability
Best When
You need a full-stack IoT platform with cellular connectivity, reliable device management, and clean REST API for Particle hardware.
Avoid When
You need hardware-agnostic IoT, AWS/Azure-scale deployments, or sub-100ms real-time requirements.
Use Cases
- • Calling functions on remote IoT devices from agents
- • Reading real-time sensor data and variables from devices
- • Publishing and subscribing to IoT events in agent workflows
- • Triggering OTA firmware updates across device fleets
- • Monitoring device connectivity and fleet health
Not For
- • Non-Particle hardware (tightly coupled to Particle ecosystem)
- • Very large scale (10K+ device) deployments without enterprise plan
- • Real-time streaming at sub-100ms latency
Interface
Authentication
OAuth 2.0 for user tokens. Product bearer tokens for product-scoped access. Customer tokens for end-user access delegation.
Pricing
Cellular data plans for Particle SIM cards billed separately. Hardware purchase required. Very competitive pricing for IoT.
Agent Metadata
Known Gotchas
- ⚠ Device function calls fail silently if device is offline - check device online status first
- ⚠ Rate limits are per token, not per device - aggregate rate limits can be hit in fleet scenarios
- ⚠ Events have a short TTL and may not be delivered if device was offline when published
- ⚠ Product access tokens vs user tokens have different scopes - product tokens recommended for agents
- ⚠ Webhook integrations require Particle-specific setup, not standard webhooks
