Warpcast-Specific Features

📡

Farcaster Protocol

Post directly to the Farcaster decentralized social protocol. Your casts are stored on-chain and accessible across all Farcaster clients.

📢

Channel Targeting

Target specific Farcaster channels to reach the right audience. Post to niche communities and topic-focused channels.

🌐

Decentralized Social

Own your social graph. Warpcast posts live on the Farcaster protocol, giving you portability and censorship resistance.

💬

Cast Composition

Compose casts with text content and optional channel targeting. Keep your messaging concise and impactful for the Farcaster audience.

🔍

Channel Discovery

Browse and target from thousands of Farcaster channels. Reach communities focused on crypto, tech, art, and more.

📅

Scheduled Casting

Schedule casts with precise timestamps. Plan your Farcaster engagement ahead of time and cast at peak activity hours.

How It Works

Find Your Warpcast Integration

List your connected accounts and grab your Warpcast integration ID. You can also fetch available settings to see what options are supported.

Discovery

# List all integrations
postiz integrations:list

# Filter for Warpcast
postiz integrations:list | jq \
  '.[] | select(.identifier=="warpcast")'

# Get Warpcast settings schema
postiz integrations:settings <warpcast-id>

Choose Your Channel

Optionally target a specific Farcaster channel for your cast. If no channel is specified, the cast will be posted to your main feed.

Channel Targeting

# Cast without a channel (main feed)
postiz posts:create \
  -c "Hello Farcaster!" \
  -i "warpcast-id"

# Cast to a specific channel
postiz posts:create \
  -c "Thoughts on decentralized social" \
  --settings '{"subreddit":[
    {"value":{"id":"decentralized"}}
  ]}' \
  -i "warpcast-id"

Create Your Cast

Schedule a Warpcast post with your content and optional channel targeting. Casts are published to the Farcaster protocol for decentralized distribution.

What is OpenClaw?

OpenClaw is the open-source personal AI agent with 145k+ GitHub stars. It runs locally on your machine, connects through apps you already use, and takes real actions on your behalf.

💬

Works Where You Are

Message OpenClaw from WhatsApp, Telegram, Slack, Discord, Signal, iMessage, or 10+ other platforms. No new app to learn.

🧩

Skill-Based Architecture

OpenClaw extends its abilities through Skills — lightweight plugins defined in Markdown files. Postiz is available as a skill on ClawHub.

⏰

Proactive Automation

Schedule recurring tasks with cron jobs. OpenClaw can publish your casts on a schedule without you having to ask each time.

How Postiz Becomes an OpenClaw Skill

When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose Warpcast posts with the right settings.

✓Install from ClawHub with one command: clawhub install nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Eligibility is checked automatically — POSTIZ_API_KEY must be set
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Install from ClawHub

# Install the Postiz skill
clawhub install nevo-david/postiz

# Or install the CLI globally
npm install -g postiz

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Verify OpenClaw sees it
openclaw skills list --eligible

# Output:
# - postiz: Social media automation
#   CLI for scheduling posts
#   across 30+ platforms

Warpcast Posting with OpenClaw

Message OpenClaw from any platform — it reads the Postiz skill, discovers your Warpcast integration, and handles the entire casting workflow autonomously.

🦀

From Any Chat App

WhatsApp, Telegram, Slack, Discord...

Send a message to OpenClaw from your favorite chat app. It runs as a persistent daemon on your machine, so it picks up your message, discovers your Warpcast account via Postiz, composes the cast, and publishes it to the Farcaster protocol.

WhatsApp / Telegram

You: Cast to the dev channel on
  Farcaster about our new open source
  tool launching today

OpenClaw: Got it! Here's what I'll do:
  1. Find your Warpcast integration
  2. Target the dev channel
  3. Compose and publish the cast

  Done! Your cast is live on Farcaster.

Scheduled & Proactive

Cron jobs for recurring content

OpenClaw supports cron-based heartbeat tasks. Set up a recurring job that composes and publishes casts to Farcaster automatically — no manual trigger needed.

openclaw.json (heartbeat)

{
  "heartbeat": [
    {
      "cron": "0 9 * * 1-5",
      "prompt": "Check ~/content/farcaster
  for new draft casts. For each one,
  publish to the dev channel on
  Warpcast via Postiz. Move posted
  drafts to ~/content/posted."
    }
  ]
}

Why OpenClaw + Postiz for Warpcast

OpenClaw's skill system makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for Warpcast workflows.

✓Message from WhatsApp to cast on Farcaster — no terminal needed
✓Cron jobs for hands-free daily casting schedules
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Target specific channels for focused community engagement
✓Cross-post to Warpcast + other platforms in a single conversation
✓Model-agnostic — works with Claude, GPT, Gemini, or open-source LLMs

Also Works with Claude Code

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including Anthropic's Claude Code.

Claude Code

by Anthropic

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your Warpcast integration, composes your cast with optional channel targeting, and publishes it to Farcaster.

Claude Code

> Cast about our product launch to the
  dev and crypto channels on Farcaster

Claude will automatically run:
  postiz integrations:list
  postiz posts:create \
    -c "We just launched! Check it out" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"subreddit":[
      {"value":{"id":"dev"}}
    ]}' \
    -i "warpcast-id"

  postiz posts:create \
    -c "New crypto tool just dropped" \
    --settings '{"subreddit":[
      {"value":{"id":"crypto"}}
    ]}' \
    -i "warpcast-id"

Warpcast + Other Platforms

Schedule the same content to Warpcast and other platforms in a single command. Each platform gets its own settings.

Terminal

# Post to Warpcast and Twitter simultaneously
postiz posts:create \
  -c "Just shipped something new! Check it out." \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "subreddit": [
      {
        "value": {
          "id": "dev"
        }
      }
    ]
  }' \
  -i "warpcast-id,twitter-id"

# Batch schedule a week of Farcaster casts
