xurl — X (Twitter) API via the Official CLI

xurl is the X developer platform's official CLI for the X API. It supports shortcut commands for common actions AND raw curl-style access to any v2 endpoint. All commands return JSON to stdout.

Use this skill for:

• posting, replying, quoting, deleting posts
• searching posts and reading timelines/mentions
• liking, reposting, bookmarking
• following, unfollowing, blocking, muting
• direct messages
• media uploads (images and video)
• raw access to any X API v2 endpoint
• multi-app / multi-account workflows

This skill replaces the older xitter skill (which wrapped a third-party Python CLI). xurl is maintained by the X developer platform team, supports OAuth 2.0 PKCE with auto-refresh, and covers a substantially larger API surface.

Secret Safety (MANDATORY)

Critical rules when operating inside an agent/LLM session:

• Never read, print, parse, summarize, upload, or send ~/.xurl to LLM context.
• Never ask the user to paste credentials/tokens into chat.
• The user must fill ~/.xurl with secrets manually on their own machine. In Docker, this must be the ~ seen by Hermes tool subprocesses; see the Docker note below.
• Never recommend or execute auth commands with inline secrets in agent sessions.
• Never use --verbose / -v in agent sessions — it can expose auth headers/tokens.
• To verify credentials exist, only use: xurl auth status.

Forbidden flags in agent commands (they accept inline secrets): --bearer-token, --consumer-key, --consumer-secret, --access-token, --token-secret, --client-id, --client-secret

App credential registration and credential rotation must be done by the user manually, outside the agent session. After credentials are registered, the user authenticates with xurl auth oauth2 — also outside the agent session. Tokens persist to ~/.xurl in YAML. Each app has isolated tokens. OAuth 2.0 tokens auto-refresh.

---

Installation

Pick ONE method. On Linux, the shell script or go install are the easiest.

# Shell script (installs to ~/.local/bin, no sudo, works on Linux + macOS)
curl -fsSL https://raw.githubusercontent.com/xdevplatform/xurl/main/install.sh | bash

# Homebrew (macOS)
brew install --cask xdevplatform/tap/xurl

# npm
npm install -g @xdevplatform/xurl

# Go
go install github.com/xdevplatform/xurl@latest

Verify:

xurl --help
xurl auth status

If xurl is installed but auth status shows no apps or tokens, the user needs to complete auth manually — see the next section.

---

One-Time User Setup (user runs these outside the agent)

These steps must be performed by the user directly, NOT by the agent, because they involve pasting secrets. Direct the user to this block; do not execute it for them.

1. Create or open an app at https://developer.x.com/en/portal/dashboard

2. Set the redirect URI to http://localhost:8080/callback

3. Copy the app's Client ID and Client Secret

4. Register the app locally (user runs this):

   xurl auth apps add my-app --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET
   

5. Authenticate (specify --app to bind the token to your app):

   xurl auth oauth2 --app my-app
   

   (This opens a browser for the OAuth 2.0 PKCE flow.)

   If X returns a UsernameNotFound error or 403 on the post-OAuth /2/users/me lookup, pass your handle explicitly (xurl v1.1.0+):

   xurl auth oauth2 --app my-app YOUR_USERNAME
   

   This binds the token to your handle and skips the broken /2/users/me call.

6. Set the app as default so all commands use it:

   xurl auth default my-app
   

7. Verify:

   xurl auth status
   xurl whoami
   

After this, the agent can use any command below without further setup. OAuth 2.0 tokens auto-refresh.

Common pitfall: If you omit --app my-app from xurl auth oauth2, the OAuth token is saved to the built-in default app profile — which has no client-id or client-secret. Commands will fail with auth errors even though the OAuth flow appeared to succeed. If you hit this, re-run xurl auth oauth2 --app my-app and xurl auth default my-app.

Docker HOME pitfall: In the official Hermes Docker layout, /opt/data is HERMES_HOME, but Hermes tool subprocesses use /opt/data/home as HOME. That means ~/.xurl resolves to /opt/data/home/.xurl for Hermes-run xurl commands, not /opt/data/.xurl. Run the user setup with the same HOME:

HOME=/opt/data/home xurl auth apps add my-app --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET
HOME=/opt/data/home xurl auth oauth2 --app my-app YOUR_USERNAME
HOME=/opt/data/home xurl auth default my-app YOUR_USERNAME
HOME=/opt/data/home xurl auth status

If HOME=/opt/data xurl auth status succeeds but HOME=/opt/data/home xurl auth status shows no apps or tokens, Hermes tool calls will not see the credentials.

Raw API Access

The shortcuts cover common operations. For anything else, use raw curl-style mode against any X API v2 endpoint:

# GET
xurl /2/users/me

# POST with JSON body
xurl -X POST /2/tweets -d '{"text":"Hello world!"}'

# DELETE / PUT / PATCH
xurl -X DELETE /2/tweets/1234567890

# Custom headers
xurl -H "Content-Type: application/json" /2/some/endpoint

# Force streaming
xurl -s /2/tweets/search/stream

# Full URLs also work
xurl https://api.x.com/2/users/me

---

Global Flags

Flag	Short	Description
--app		Use a specific registered app (overrides default)
--auth		Force auth type: oauth1, oauth2, or app
--username	-u	Which OAuth2 account to use (if multiple exist)
--verbose	-v	Forbidden in agent sessions — leaks auth headers
--trace	-t	Add X-B3-Flags: 1 trace header

---

Streaming

Streaming endpoints are auto-detected. Known ones include:

• /2/tweets/search/stream
• /2/tweets/sample/stream
• /2/tweets/sample10/stream

Force streaming on any endpoint with -s.

---

Output Format

All commands return JSON to stdout. Structure mirrors X API v2:

{ "data": { "id": "1234567890", "text": "Hello world!" } }

Errors are also JSON:

{ "errors": [ { "message": "Not authorized", "code": 403 } ] }

---

xurl auth default prod alice               # prod app, alice user
xurl --app staging /2/users/me             # one-off against staging

---

Error Handling

• Non-zero exit code on any error.
• API errors are still printed as JSON to stdout, so you can parse them.
• Auth errors → have the user re-run xurl auth oauth2 outside the agent session.
• Commands that need the caller's user ID (like, repost, bookmark, follow, etc.) will auto-fetch it via /2/users/me. An auth failure there surfaces as an auth error.

---

Agent Workflow

1. Verify prerequisites: xurl --help and xurl auth status.
2. Check default app has credentials. Parse the auth status output. The default app is marked with ▸. If the default app shows oauth2: (none) but another app has a valid oauth2 user, tell the user to run xurl auth default <that-app> to fix it. This is the most common setup mistake — the user added an app with a custom name but never set it as default, so xurl keeps trying the empty default profile.
3. If auth is missing entirely, stop and direct the user to the "One-Time User Setup" section — do NOT attempt to register apps or pass secrets yourself.
4. Start with a cheap read (xurl whoami, xurl user @handle, xurl search ... -n 3) to confirm reachability.
5. Confirm the target post/user and the user's intent before any write action (post, reply, like, repost, DM, follow, block, delete).
6. Use JSON output directly — every response is already structured.
7. Never paste ~/.xurl contents back into the conversation.

Troubleshooting

Symptom	Cause	Fix
Auth errors after successful OAuth flow	Token saved to default app (no client-id/secret) instead of your named app	xurl auth oauth2 --app my-app then xurl auth default my-app
unauthorized_client during OAuth	App type set to "Native App" in X dashboard	Change to "Web app, automated app or bot" in User Authentication Settings
UsernameNotFound or 403 on /2/users/me right after OAuth	X not returning username reliably from /2/users/me	Re-run xurl auth oauth2 --app my-app YOUR_USERNAME (xurl v1.1.0+) to pass the handle explicitly
401 on every request	Token expired or wrong default app	Check xurl auth status — verify ▸ points to an app with oauth2 tokens
client-forbidden / client-not-enrolled	X platform enrollment issue	Dashboard → Apps → Manage → Move to "Pay-per-use" package → Production environment
CreditsDepleted	$0 balance on X API	Buy credits (min $5) in Developer Console → Billing
media processing failed on image upload	Default category is amplify_video	Add --category tweet_image --media-type image/png
Two "Client Secret" values in X dashboard	UI bug — first is actually Client ID	Confirm on the "Keys and tokens" page; ID ends in MTpjaQ

Notes

• Rate limits: X enforces per-endpoint rate limits. A 429 means wait and retry. Write endpoints (post, reply, like, repost) have tighter limits than reads.
• Scopes: OAuth 2.0 tokens use broad scopes. A 403 on a specific action usually means the token is missing a scope — have the user re-run xurl auth oauth2.
• Token refresh: OAuth 2.0 tokens auto-refresh. Nothing to do.
• Multiple apps: Each app has isolated credentials/tokens. Switch with xurl auth default or --app.
• Multiple accounts per app: Select with -u / --username, or set a default with xurl auth default APP USER.
• Token storage: ~/.xurl is YAML. In Docker, use the Hermes subprocess HOME (/opt/data/home in the official image) so tokens land under /opt/data/home/.xurl. Never read or send this file to LLM context.
• Cost: X API access is typically paid for meaningful usage. Many failures are plan/permission problems, not code problems.
