Developers — Direct API

API Features

Developer-first infrastructure

REST API v1

Versioned endpoints with Swagger/OpenAPI documentation. Standard HTTP verbs, JSON payloads.

Real-Time WebSocket

SignalR-powered bi-directional streams. Subscribe to live telemetry and push commands to devices.

Time-Series Storage

High-write-throughput time-series backend. Query historical data with flexible time ranges and aggregations.

Multi-Stream

Organize data into named streams per device. Battery, motor, environment — each stream has its own schema.

API Key Auth

Simple Bearer token authentication. Scoped keys per device, project, or organization.

Dashboards Included

Data you send via API automatically appears in QuantaCloud dashboards — no extra setup needed.

import requests

response = requests.post(
    "https://api.quantaflare.com/v1/telemetry",
    headers={
        "Authorization": f"Bearer {API_KEY}",
    },
    json={

C# / .NET

              
              Program.cs
            

var client = new HttpClient();
client.DefaultRequestHeaders.Authorization =
    new AuthenticationHeaderValue("Bearer", apiKey);

var payload = new {
    device_id = "robot-arm-01",
    stream = "battery",
    data = new {
        voltage = 48.2,
        current = 12.5,
        soc = 78.3
    }
};

var response = await client.PostAsJsonAsync(
    "https://api.quantaflare.com/v1/telemetry",
    payload
);
