   echo "X_ACCESS_TOKEN=xxx" >> ~/.openclaw/.env
   echo "X_ACCESS_TOKEN_SECRET=xxx" >> ~/.openclaw/.env
   

Test your credentials:

# Dry run (won't post)
scripts/post.sh --twitter --dry-run "Test message"

Farcaster Setup

Required credentials (stored in /home/phan_harry/.openclaw/farcaster-credentials.json):

{
  "fid": "your_farcaster_id",
  "custodyAddress": "0x...",
  "custodyPrivateKey": "0x...",
  "signerPublicKey": "0x...",
  "signerPrivateKey": "0x...",
  "createdAt": "2026-01-01T00:00:00.000Z"
}

How to get credentials:

1. Use farcaster-agent skill to create account

   # This will guide you through:
   # - Creating a wallet
   # - Registering FID
   # - Adding signer key
   # - Automatically saving credentials
   
   # See: /skills/farcaster-agent/SKILL.md
   

2. Or use existing credentials

   • If you already have a Farcaster account
   • Export your custody wallet private key
   • Export your signer private key
   • Manually create the JSON file

3. Fund the custody wallet (REQUIRED)

   # Check current balance
   scripts/check-balance.sh
   
   # Send USDC to custody address on Base chain
   # Minimum: 0.1 USDC (~100 casts)
   # Recommended: 1-5 USDC (1000-5000 casts)
   

4. Verify setup

   # Check credentials exist
   ls -la ~/.openclaw/farcaster-credentials.json
   
   # Check wallet balance
   scripts/check-balance.sh
   
   # Test posting (dry run)
   scripts/post.sh --farcaster --dry-run "Test message"
   

Security Notes:

• ⚠️ Never share your private keys
• ⚠️ Credentials are stored as plain text - secure your system
• ⚠️ .env file should have 600 permissions (read/write owner only)
• ⚠️ Back up your credentials securely

Draft Preview

The script now shows a draft preview before posting:

=== Draft Preview ===

Text to post:
─────────────────────────────────────────────
Your message here
─────────────────────────────────────────────

Targets:
  • Twitter
  • Farcaster

Proceed with posting? (y/n):

• Interactive mode: Prompts for confirmation
• Non-interactive/automated: Use --yes flag to skip prompt
• Dry run: Use --dry-run to preview without any posting

Requirements

• Twitter credentials in .env (X_CONSUMER_KEY, X_CONSUMER_SECRET, X_ACCESS_TOKEN, X_ACCESS_TOKEN_SECRET)
• Farcaster credentials in /home/phan_harry/.openclaw/farcaster-credentials.json
• USDC on Base chain (custody wallet): 0.001 USDC per Farcaster cast
• For images: curl, jq

Costs

X/Twitter

• 100% Consumption-based - NO subscription tiers (tiers have been eliminated)
• Pay per API request - charged for each call (post, read, etc.)
• No monthly fees, no minimums, no tier upgrades to worry about
• Automatic billing based on actual usage
• Payment via credit card through X Developer portal
• Uses OAuth 1.0a (no blockchain/USDC required)
• Requires approved X Developer account + enabled billing

Official pricing: https://developer.twitter.com/#pricing

Critical: X API completely eliminated subscription tiers (Basic, Pro, etc.). The model is now purely pay-per-use - you are charged only for the API requests you actually make.

Farcaster

Each Farcaster cast costs 0.001 USDC (paid via x402 protocol):

• Deducted from custody wallet on Base chain
• Sent to Neynar Hub: 0xA6a8736f18f383f1cc2d938576933E5eA7Df01A1
• ~$1 USDC = 1000 casts

Check balance:

# Quick check
scripts/check-balance.sh

# Manual check
jq -r '.custodyAddress' ~/.openclaw/farcaster-credentials.json
# View on basescan.org

Fund wallet: Send USDC to custody address on Base chain. Bridge from other chains if needed.

Image Hosting

• Twitter: Direct upload via Twitter API
• Farcaster: Uploads to imgur for public URL (embeds automatically)

Error Handling

• Shows character/byte count before posting
• Warns if exceeding limits
• Option to truncate or abort
• Validates credentials before attempting post
