description	Unified X (Twitter) CLI — fetch follows, diff snapshots, get likes/bookmarks, fetch latest posts, and take screenshots. Uses the official X API v2 with Bearer Token and OAuth 2.0 user-context auth.

X CLI — Unified X (Twitter) Tool

Use the xapi CLI tool to interact with X (Twitter) via the official API v2. No cookies or scraping required.

Backward-compatible alias: twitter also points to the same CLI.

Setup

Bearer Token (required for most commands)

Get one from the X Developer Portal:

1. Create or select a project/app
2. Under "Keys and Tokens", find your Bearer Token
3. Set the environment variable:

export X_BEARER_TOKEN='your_token_here'

OAuth 2.0 User Access Token (required for likes/bookmarks)

The likes and bookmarks endpoints require an OAuth 2.0 user access token — app-only Bearer Tokens are not supported for these.

1. In the Developer Portal, go to your app's Settings → User authentication settings → Set up
2. Enable OAuth 2.0 and select Web App (confidential client)
3. Set a callback URL (e.g. http://localhost:3000/callback)
4. Complete the OAuth 2.0 PKCE flow to get an access token
5. Request scopes: like.read, bookmark.read, tweet.read, users.read, offline.access
6. Set the environment variables:

export X_ACCESS_TOKEN='your_user_access_token_here'
export X_REFRESH_TOKEN='your_refresh_token_here'  # optional, for future token refresh support

Resolve a Username

xapi resolve elonmusk

Fetch a Following Snapshot

# Auto-saves to ~/.x/<username>_<timestamp>.json
xapi fetch elonmusk

# Save to a specific file
xapi fetch elonmusk -o /tmp/elon_following.json

# Verbose mode shows progress
xapi fetch elonmusk -v

Diff Two Snapshots

Compare two snapshots to detect new follows and unfollows:

# Basic diff
xapi diff snapshot_before.json snapshot_after.json

# Save diff output to file
xapi diff before.json after.json -o diff_result.json

# Also fetch the latest post for each unfollowed account
# (uses the newer snapshot's timestamp as cutoff)
xapi diff before.json after.json --fetch-posts -v

xapi latest-post someuser --before-post 1234567890

# Save to file
xapi latest-post someuser -o latest.json

Fetch Likes

# Fetch liked tweets for the default user (HamelHusain)
xapi likes

Environment Variables

• X_BEARER_TOKEN — X API Bearer Token (required for resolve, fetch, diff, latest-post; also used by likes/bookmarks to resolve usernames)
• X_ACCESS_TOKEN — OAuth 2.0 user access token (required for likes and bookmarks)
• X_REFRESH_TOKEN — OAuth 2.0 refresh token (optional, for future token refresh support)
• X_DEFAULT_USERNAME — Override the default username for likes/bookmarks (optional, default: HamelHusain)

If a required variable is missing, the CLI exits with a clear error explaining what is needed and how to set it up.

Default Username

The likes and bookmarks commands default to HamelHusain if no username is provided.

Three ways to override (pick one):

1. Environment variable (recommended for skill installers): Set X_DEFAULT_USERNAME to change the default for all invocations without editing code:

   export X_DEFAULT_USERNAME='yourusername'
   

   Add this to your ~/.bashrc or ~/.zshrc to persist it.

2. Per-invocation: Pass a username argument to override just that call:

   xapi likes otherusername
   xapi bookmarks otherusername
   

3. Edit source code: Change _FALLBACK_USERNAME at the top of hamel/x_cli.py:

   _FALLBACK_USERNAME = "YourUsername"
   

Requirements

The hamel package must be installed: pip install hamel

For xapi screenshot: Playwright is included as a dependency, but you need to install browser binaries:

playwright install chromium

Verify Setup

After installing and setting the environment variables, run these commands to confirm everything works:

# 1. Check the CLI is installed
xapi --help

# 2. Test API access (lightweight call — uses X_BEARER_TOKEN)
xapi resolve github

# 3. Test latest post
xapi latest-post someuser

# 4. Test likes (requires X_ACCESS_TOKEN, defaults to HamelHusain)
xapi likes --limit 5

# 5. Test bookmarks (requires X_ACCESS_TOKEN, defaults to HamelHusain)
xapi bookmarks --limit 5

If xapi resolve github returns a JSON object with "username": "github", your Bearer Token is working. If xapi likes returns JSON, your OAuth 2.0 user access token is working.

Known Limitations

• Likes and bookmarks require X_ACCESS_TOKEN. These endpoints use OAuth 2.0 user-context auth and do not work with X_BEARER_TOKEN alone. You need to complete the OAuth 2.0 PKCE flow and set X_ACCESS_TOKEN. Required scopes: like.read (likes), bookmark.read (bookmarks), tweet.read, users.read.
• Timeline window. The user timeline endpoint only returns posts from approximately the last 7 days with app-only Bearer Token auth. Using --before with older dates will return no results.
• Protected accounts. App-only auth cannot access following lists or tweets for protected accounts.

Rate Limits

The X API has rate limits per 15-minute window. The tool automatically handles rate limiting by waiting and retrying. For large following lists (>15k), fetches may take several minutes due to pagination and rate limits.

Troubleshooting

"X_BEARER_TOKEN environment variable is not set": Get a Bearer Token from the X Developer Portal and export it.

"API error 401": Your Bearer Token may be invalid or expired. Regenerate it in the Developer Portal.

"X_ACCESS_TOKEN environment variable is not set": Complete the OAuth 2.0 PKCE flow in the Developer Portal and set the token. See Setup section above.

"API error 403": For likes/bookmarks, ensure X_ACCESS_TOKEN is set (app-only Bearer Tokens are not supported). For other endpoints, check your app's access level in the Developer Portal.

"API error 429": Rate limited. The tool waits automatically, but if it persists, wait 15 minutes.

Empty following list: The account may be protected. App-only auth cannot access protected accounts' following lists.

playwright not installed: For screenshots, install with pip install playwright && playwright install chromium.

Examples

Monitor follows over time:

xapi fetch someuser -o ~/snapshots/day1.json
# ... later ...
xapi fetch someuser -o ~/snapshots/day2.json
xapi diff ~/snapshots/day1.json ~/snapshots/day2.json --fetch-posts -v

Download likes and analyze with AI:

xapi likes -o /tmp/likes.json
ai-gem "What topics am I most interested in based on my likes?" /tmp/likes.json

Export bookmarks:

xapi bookmarks -o ~/bookmarks-backup.json

Get the last post before a specific tweet:

xapi latest-post someuser --before-post 1234567890
