Bird Fast

bird CLI

A command-line interface for X/Twitter that authenticates via your existing browser session — no API keys or OAuth setup required.

Overview

bird is a TypeScript-based CLI that uses Twitter's internal GraphQL API with automatic query ID management. It extracts authentication cookies from Safari, Chrome, or Firefox.

Key Features:

• Zero-config 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
• Monitoring Twitter activity from the CLI

Prerequisites

• Node.js >= 22 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

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

# One-shot execution (no install)
bunx @steipete/bird whoami
npx @steipete/bird whoami

Authentication

bird uses a three-tier priority chain:

Verify authentication:

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

Examples

Daily Automation Script

#!/bin/bash
DATE=$(date +"%B %d, %Y")
bird tweet "Daily status for $DATE: All systems operational. #status"

Thread Analysis

# Get all replies to a viral tweet as JSON
bird replies https://x.com/user/status/1234567890123456789 --json | \
  jq '.[] | {user: .user.screen_name, text: .text, likes: .favorite_count}'

Multi-Image Product Post

bird tweet "Product launch gallery 🚀" \
  --media hero.png --alt "Product hero shot" \
  --media feature1.png --alt "Feature overview" \
  --media feature2.png --alt "Technical specs" \
  --media pricing.png --alt "Pricing table"

Monitor Mentions and Reply

#!/bin/bash
bird mentions -n 20 --json | jq -r '.[] | "\(.id) \(.user.screen_name): \(.text)"'

Best Practices

• Use --json for scripting — always when parsing output programmatically
• Use --plain in CI/CD — avoids emoji/color issues in logs
• Add alt text — always include --alt when attaching images
• Refresh query IDs proactively — run bird query-ids --fresh if bird hasn't been used in a few days
• Set env vars for automation — use AUTH_TOKEN / CT0 instead of browser cookies in scripts
• Handle rate limits — Twitter throttles; add delays (sleep) in bulk automation scripts

Troubleshooting

"No auth token found"

# Verify you're logged into x.com in your browser
# Try specifying the browser explicitly
bird whoami --cookie-source safari

# Or set credentials via environment
export AUTH_TOKEN="your-auth-token"
export CT0="your-ct0-token"
bird whoami

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 cached at ~/.config/bird/query-ids-cache.json (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 internal APIs
