Zero to X Posting in 20 Minutes
A practical guide for OpenClaw newcomers. Get your AI agent tweeting automatically.
What You're Building
A headless X bot that can:
- Post tweets from the command line
- Reply to mentions automatically
- Like and retweet programmatically
- Follow users in bulk
Time to first tweet: 20 minutes if you follow exactly.
Step 1: Get Your X Credentials (5 min)
"API Keys" sound scary. They're not. Think of them like a password X gives your bot so it can post.
1.1 Sign Up at X Developer Portal
- Go to developer.x.com
- Sign in with your X account
- Click "Apply" for a developer account
- Choose "Basic" tier (free, or $100/mo if you need more)
- Answer honestly: "I'm building an AI assistant for content automation"
1.2 Create Your App
Once approved:
- Go to "Projects & Apps" → "Overview"
- Click "Create App"
- Name it something like "MyAIAssistant"
- Copy these values:
- API Key
- API Secret
- Go to "Keys and Tokens" tab
- Generate Access Token and Access Token Secret
1.3 Get Your User ID
Your user ID is a number X uses internally. Easiest way:
- Go to tweeterid.com
- Enter your X handle (without @)
- Copy the number
💡 Pro tip: You now have 5 credentials. Save them in a password manager.
Step 2: Install OpenClaw
If you're reading this, OpenClaw is working. Skip to Step 3.
If not: buy a Hostinger VPS, SSH in, run the one-liner install from openclaw.ai, return here.
Step 3: Install the Skill (5 min)
Skills are plugins that give your agent new powers. The xpost skill gives it X superpowers.
3.1 Install via ClawHub
# Pull the skill from the registry
clawhub install x-api
# Or if you have the tar.gz locally
cd /data/.openclaw/workspace
clawhub install ./xpost.skill.tar.gz
3.2 Verify Installation
# Should see the xpost command now
which xpost
# Output: /data/clawd/bin/xpost
# Test help
xpost
# Should show usage instructions
Step 4: Configure Credentials (2 min)
Your agent needs the keys to drive. Create a config file:
mkdir -p ~/.config/x-api
cat > ~/.config/x-api/keys.env << 'EOF'
X_API_KEY=your_api_key_here
X_API_SECRET=your_api_secret_here
X_ACCESS_TOKEN=your_access_token_here
X_ACCESS_TOKEN_SECRET=your_access_token_secret_here
X_USER_ID=your_numeric_user_id_here
EOF
Replace the values with what you copied in Step 1.
Test It
xpost mentions
If you see JSON output (possibly empty []), you're authenticated. If you see "Error," check your credentials.
Step 5: Post Your First Tweet (30 seconds)
This is the moment. Type:
xpost post "My AI just posted this. I'm now a cyborg."
Check your X timeline. It's there.
Step 6: Hook It Into Your Agent (5 min)
Posting manually is cool. Having your agent post automatically is power.
Option A: Quick Command
xpost post "Just shipped a new feature. Building in public hits different."
Option B: Scheduled Queues (The Real Power)
Create a queue file your agent checks:
{
"timezone": "America/New_York",
"posts_per_day": 2,
"schedule": ["09:00", "18:00"],
"queue": [
{
"id": 1,
"status": "scheduled",
"time": "2026-03-01T09:00:00",
"content": "Why I use Kimi K2.5 via NVIDIA NIM..."
}
]
}
Then add to your HEARTBEAT.md:
## X Auto-Posting
Check x-tweet-queue.json every heartbeat. If current time matches
scheduled post time (within 5 min), post via xpost and mark as posted.
Now your agent posts automatically on schedule.
Step 7: Engagement Automation
Auto-Reply to Mentions
Add to your daily checks:
xpost mentions
Like/Retweet Workflow
xpost like 1234567890
xpost retweet 1234567890
xpost follow @levelsio
Common Errors & Fixes
"403 Forbidden"
Rate limit or action blocked. Wait 15 minutes. X limits: 200 tweets/15min.
"Auth errors"
Credentials wrong. Triple-check the keys.env file.
Tweet won't post
Probably over character limit. X limit is 280 chars.
Your Mission
- Post one tweet manually
- Tell your agent to post one for you
- Set up a scheduled queue with 3 tweets
- Check mentions once
Don't overthink. Don't perfect. Just ship.
Ship Fast
"If it takes longer than an hour to set up, it's too complex"
This took 20 minutes. Now you have a system. Not a "strategy." A working bot that posts while you sleep.
