rpinfo is a lightweight RESTful API server written in Go that exposes
detailed system information for Raspberry Pi devices. It utilizes the
vcgencmd utility to provide real-time hardware data such as CPU temperature,
voltages, firmware configuration, throttling status and clock frequencies.
- Exposes Raspberry Pi system metrics via a clean RESTful API
- Supports optional bearer token authentication
- Configurable host and port via command-line flags
- Fast and efficient Go implementation
- Ideal for integration with dashboards, monitoring tools, or automation scripts
- Raspberry Pi running a Linux-based OS (e.g., Raspberry Pi OS)
vcgencmdutility (preinstalled on Raspberry Pi OS)

Start the server on localhost:8080 by default.
./rpinfo serverFor further configuration, see the command-line options below.
| Flag | Description | Default |
|---|---|---|
-H, --host |
Host to bind the server to | localhost |
-p, --port |
Port to run the server on | 8080 |
-a, --auth |
Enable bearer token authentication | false |
-t, --token |
Bearer token used for authentication | |
-h, --help |
Show help for the server command |
Additional a systemd service file and environment file are provided in the contrib directory for automatic startup on boot and management of the server.
| Endpoint | Description |
|---|---|
/configuration |
Returns firmware configuration |
/temperature |
Returns CPU temperature |
/throttled(?human=true) |
Returns throttling status |
/voltages |
Returns voltages |
/clock |
Returns clock frequencies |
All endpoints return JSON-formatted data.
The complete API specification is available at /redoc.
- If authentication is enabled, all API calls must include the
Authorizationheader with the valid bearer token. - Use strong and random tokens.
- Consider running the server behind HTTPS if exposed publicly.
