X OAUTH API

X OAuth API Skill

Post to X (formerly Twitter) using the official X API with OAuth 1.0a authentication.

Overview

This skill provides direct access to X API v2 for posting tweets, managing threads, and monitoring mentions. No proxy or third-party service required — uses your X API credentials directly.

Use when:

• User says "post to X", "tweet this", "post on Twitter"
• Need to create threads or media posts
• Want to check mentions or engage with replies

Quick Start

1. Configure X API Credentials

Store these environment variables (from your X Developer Account):

X_API_KEY              # Consumer Key (API Key)
X_API_SECRET           # Consumer Secret
X_ACCESS_TOKEN         # Access Token
X_ACCESS_TOKEN_SECRET  # Access Token Secret
X_USER_ID              # Optional: Your numeric user ID (speeds up mentions)

Free Tier vs Paid Tier

Free tier supports:

• ✅ Posting tweets and threads
• ✅ Deleting tweets
• ✅ Account info lookup (x me)

Requires Basic+ tier:

• 🔒 Search tweets
• 🔒 Fetch mentions
• 🔒 Media uploads

Authentication

OAuth 1.0a is handled transparently. Just provide your credentials via environment variables. The skill will sign all requests automatically.

Examples

Post with media

x post "Check out this screenshot" --media screenshot.png

Reply to a tweet

x post "Great point!" --reply-to 1234567890123456789

Create a 3-tweet thread

x thread \
  "Just launched x-oauth-api skill" \
  "It lets you post to X directly from your agent" \
  "No proxies, direct OAuth 1.0a authentication"

Search and reply

# Find interesting tweets
x search "agent framework"

# Reply to one
x post "Have you tried this?" --reply-to 1234567890123456789
