Detailed Description

Minimal REST Spot Example

This example demonstrates the simplest possible implementation of the SmartSpectra C++ SDK for spot measurements using the REST API integration.

Overview

The minimal REST spot example shows how to:

• Configure basic spot measurement settings
• Set up REST API integration
• Perform a single 30-second physiological measurement
• Handle basic callbacks for metrics output

Key Features

• Minimal code footprint - Demonstrates the absolute minimum required to get started
• REST API integration - Uses HTTP REST calls instead of gRPC
• Spot measurement mode - Single measurement rather than continuous monitoring
• Basic error handling - Simple logging and error reporting

Usage

# Build the example (from smartspectra/cpp directory)
cmake --build build --target minimal_rest_spot_example
 
# Run with your API key
./build/samples/minimal_rest_spot_example/minimal_rest_spot_example

Configuration

Before running, make sure to set your API key in the source code:

settings.integration.api_key = "YOUR_API_KEY_HERE";

Code Structure

The example consists of a single main.cc file that:

1. Initializes logging - Sets up Google logging for debug output
2. Configures settings - Sets up spot measurement and REST integration parameters
   
3. Creates container - Instantiates the SmartSpectra processing container
4. Starts measurement - Begins the 30-second spot measurement
5. Handles callbacks - Processes physiological metrics as they're generated
6. Cleanup - Properly shuts down the measurement system

This example serves as the starting point for developers who want to integrate basic physiological measurements into their applications with minimal overhead.
