Core Nodes

Core Nodes are the essential building blocks of any workflow. They provide utilities, data processing, validation, communication tools, and logic routing that allow you to build powerful automations step-by-step.

This page provides a complete overview of each Core Node category and the tools they contain.

Crypto Nodes

Crypto nodes allow you to securely transform, sign, or generate data.

Hash Data

Generate cryptographic hash values using popular algorithms such as SHA-256, SHA-1, MD5, and more.

Use cases:

  • Store passwords securely
  • Verify data integrity
  • Generate unique identifiers

HMAC Generation

Generate HMAC signatures for secure API authentication.

Use cases:

  • Signing API requests
  • Validating payload integrity
  • Secure communication between services

Generate Random Data

Create secure random values.

Common outputs:

  • Random strings
  • Random numbers
  • Unique keys or tokens

CSV Processor

Process CSV files with ease.

Read CSV

Convert CSV content into structured JSON data.

Use cases:

  • Import spreadsheets
  • Parse large data sets
  • Automate report ingestion

Write CSV

Convert JSON objects into CSV files.

Use cases:

  • Export data
  • Generate automated CSV reports
  • Provide downloadable files

Data Validator

Validate user input or external data to ensure workflows operate safely.

Includes:

  • Validate Email
  • Validate Password
  • Validate Phone Number
  • Validate Credit Card
  • Validate Date
  • Validate URL
  • Validate Markdown

Typical workflow:

  1. Receive raw data
  2. Validate using this node
  3. Branch workflow based on validation status

Delay Utilities

Control execution timing inside your workflow.

Delay For

Pause the workflow for a specified duration (seconds, minutes, hours, days).

Delay Until

Schedule the workflow to continue at a future timestamp.

Use cases:

  • Rate limiting
  • Throttling API calls
  • Scheduled follow-ups
  • Creating cooldown periods

HTTP Utilities

Interact with external APIs or download files.

Send HTTP Request

Supports:

  • GET / POST / PUT / DELETE
  • Custom headers
  • Query parameters
  • JSON / form-data / raw bodies

Perfect for integrating with third-party services.

Download File

Download files from any URL and attach them to workflow output.

Use cases:

  • Fetch reports
  • Download images
  • Sync files between systems

Image Tools

Resize Image

Modify image dimensions (width, height, quality).

Use cases:

  • Prepare images for upload
  • Compress images for storage

JSON Tools

Work with JSON objects easily.

Parse JSON

Convert a JSON string into a structured object.

Stringify JSON

Convert structured data back into a JSON string.

Extract JSON Value

Pull a nested value using JSON paths.

Example:

{
  "user": { "profile": { "email": "test@example.com" } }
}

Extraction path:

user.profile.email

Merge JSON Object

Combine multiple JSON objects into one.

Loop Node

Execute a set of nodes repeatedly.

Supports:

  • Looping over arrays
  • Running until a condition is met
  • Fixed number of iterations

Use cases:

  • Batch processing
  • Paginated API calls
  • Complex iterative logic

Model Router (AI Text Model)

Route text queries through an AI model or different model providers.

Use cases:

  • Smart content analysis
  • Classification
  • AI-driven routing
  • Model fallback strategy

QR Code Tools

Generate QR Code

Create a QR code from text, URLs, or dynamic data.

Read QR Code

Extract text from an uploaded QR code image.

Use cases:

  • Ticketing systems
  • Authentication flows
  • Sharing links
  • Inventory management

Router Node

Branch your workflow based on conditions.

Supports:

  • If / Else branching
  • Complex logical conditions
  • Multiple outputs

Example conditions:

  • price > 100
  • status == “success”
  • email.contains(“@gmail.com”)

RSS Reader

RSS Read

Reads data from an RSS feed and returns structured items.

Use cases:

  • News monitoring
  • Blog update alerts
  • Event-based RSS workflows

Server Monitoring

Tools for checking system health and connectivity.

Server Health

Monitor performance metrics with comparative checks.

Monitor Port

Check if a port is open and responding.

Use cases:

  • Uptime monitoring
  • Detecting service interruptions
  • Alerting when a service goes offline

SSH Tools

Connect to remote servers.

Execute Command

Run shell commands on a remote machine via SSH.

Connection Test

Verify SSH connectivity before running commands.

Use cases:

  • Deployment automation
  • Server maintenance
  • Remote scripts

TOTP Tools

Generate TOTP Token

Create time-based one-time passwords.

Verify TOTP Token

Validate a TOTP token against a shared secret.

Use cases:

  • 2FA authentication flows
  • Secure user login
  • One-time access validation

XML Parser

Parse XML

Convert XML into JSON.

Generate XML

Convert JSON into XML format.

Use cases:

  • Enterprise system integrations
  • Legacy API transformations
  • Config file processing

Summary

Core Nodes provide everything you need to:

  • Validate data
  • Process files
  • Interact with the web
  • Run loops
  • Parse/transform JSON & XML
  • Execute server commands
  • Create QR codes
  • Monitor systems
  • Use cryptographic utilities

They form the foundation of every workflow and enable powerful, flexible automation.
