Picarro Edge — SAM FOUP gRPC API is one of 4 APIs that [Picarro](https://apis.io/providers/picarro/) publishes on the [APIs.io](https://apis.io/) network, described by an AsyncAPI event-driven specification. Tagged areas include gRPC, Protobuf, Semiconductors, Gas Detection, and Event. The published artifact set on APIs.io includes an AsyncAPI specification and API documentation.

The first-party gRPC/ProtoBuf interface Picarro publishes for external access to Picarro SAM (semiconductor airborne molecular contamination) systems. The `picarro-edge` server exposes three services — FOUP for starting, aborting and retrieving FOUP measurement jobs, MeasurementSet for managing which compounds are measured, and Controller for streaming instrument health alerts. Every service also exposes a server-streaming `watch()` signal feed that acts as a pub/sub event channel. Interface definitions, Python client wheels, Debian packages and command-line tools are published openly on GitHub.
