Bird Fast

bird CLI

A command-line interface for interacting with X/Twitter directly from the terminal, using your existing browser session for authentication.

Overview

bird is a TypeScript-based CLI that provides terminal access to X/Twitter functionality without requiring API keys or OAuth flows. It extracts authentication cookies from your web browser (Safari, Chrome, or Firefox) and uses Twitter's internal GraphQL API with automatic query ID management.

Key Features:

• Zero-configuration authentication via browser cookies
• Full tweet lifecycle: post, reply, read, search
• Media uploads (images, GIFs, videos) with alt text
• Multiple output formats (human-readable, JSON, plain)
• Automatic GraphQL query ID refresh and REST API fallback

When to Use

• Posting tweets or replies from scripts or automation
• Reading and analyzing tweet threads programmatically
• Searching for mentions or specific content
• Building social media automation workflows
• Testing Twitter integrations from the command line
• Extracting tweet content for analysis

Prerequisites

• Node.js >= 22 (for npm/pnpm/bun installation) OR Homebrew (for standalone binary)
• Browser login: Must be logged into x.com in Safari, Chrome, or Firefox

Installation

# npm
npm install -g @steipete/bird

# pnpm
pnpm add -g @steipete/bird

# bun
bun add -g @steipete/bird

# Homebrew (macOS - standalone binary, no Node.js required)
brew install steipete/tap/bird

One-shot execution without installation:

bunx @steipete/bird whoami
npx @steipete/bird whoami

Authentication

bird resolves credentials using a three-tier priority chain:

Browser cookie extraction (default behavior):

• Requires being logged into x.com in your browser
• Default order: Safari → Chrome → Firefox
• Customize with --cookie-source flag or config file

Verify authentication:

bird whoami    # Shows authenticated user
bird check     # Shows credential source

Best Practices

• Use --json for scripting: Always use --json output when parsing results programmatically
• Use --plain in CI/CD: Avoids emoji/color issues in log files
• Refresh query IDs proactively: Run bird query-ids --fresh if you haven't used bird in a while
• Set up environment variables for automation: Use AUTH_TOKEN and CT0 env vars instead of browser cookies for scripts
• Add alt text for accessibility: Always include --alt when attaching images
• Check auth first: Run bird whoami before complex operations to verify credentials
• Handle rate limits: Twitter may throttle requests; add delays in automation scripts

Troubleshooting

"No auth token found"

• Ensure you're logged into x.com in Safari, Chrome, or Firefox
• Try specifying the browser: bird whoami --cookie-source safari
• Use environment variables: export AUTH_TOKEN=... CT0=...

GraphQL 404 errors

Query IDs may be stale. Refresh the cache:

bird query-ids --fresh

Error 226 (automation detected)

bird automatically falls back to the REST API. If it persists, wait a few minutes and retry.

Wrong account detected

Multiple browser profiles may have different sessions:

bird whoami --cookie-source chrome --chrome-profile "Profile 1"

Exit Codes

Technical Notes

• Uses Twitter's private GraphQL API endpoints
• Query IDs are cached locally (~/.config/bird/query-ids-cache.json) with 24-hour TTL
• Automatic query ID refresh on 404 errors
• REST API fallback (statuses/update.json) for error 226
• Subject to breakage if Twitter changes their internal API
