Quick Start Guide

Build your first API in under 5 minutes. No infrastructure required.

1 Create Your First Block

Open the Dashboard and click anywhere on the canvas to create a new block.

Select "Process" as the block type to write JavaScript code.

// Example: Transform input data
const data = input;
return {
    message: "Hello from Qu4zr!",
    timestamp: new Date().toISOString(),
    received: data
};
            

2 Test Your Block

Click the Run button in the execution panel to test your block.

The output will appear in the "Final Flow Output" editor below.

Tip: Use console.log() in your code for debugging. Logs appear in the execution logs viewer.

3 Deploy as an API Endpoint

Change the block type to "API Endpoint" in the bottom panel.

Configure your endpoint:

Create a Domain (e.g., "my-api")
Set the Path (e.g., "/hello")
Select allowed HTTP Methods (GET, POST, etc.)

Your API is now live at:

https://api.qu4zr.io/my-api/hello

4 Call Your API

Generate an API key from the Domain settings, then call your endpoint:

curl -X GET "https://api.qu4zr.io/my-api/hello" \
     -H "Authorization: Bearer YOUR_API_KEY"
            

Or use the query parameter method:

curl "https://api.qu4zr.io/my-api/hello?code=YOUR_API_KEY"

Block Types

Process - Write JavaScript to transform data. Has access to input from connected blocks.
Raw Data - Store static JSON or text data. Useful for configuration or test data.
API Endpoint - Expose a block as an HTTP endpoint. Access request data via input.body, input.query, input.method.
SignalR - Execute code on your own infrastructure. Data never leaves your network.

Connecting Blocks

Create data flows by linking blocks together:

Select a block and click the Link button in the floating toolbar
Click on the target block to create a connection
The output of the source block becomes the input of the target block

Tip: When multiple blocks connect to one target, their outputs are merged into a single input object.

SignalR Remote Execution

Run code on your own servers while designing in the cloud:

Create a SignalR block in your workflow
Download the pre-configured .NET runner template
Run dotnet run on your server
The block executes locally - logs stream back to your dashboard

Perfect for accessing internal databases, legacy systems, or compliance-sensitive data.
