xurl

name	xurl
description	A curl-like CLI tool for making authenticated requests to the X (Twitter) API. Use this skill when you need to post tweets, reply, quote, search, read posts, manage followers, send DMs, send or read end-to-end encrypted XChat messages, upload media, or interact with any X API v2 endpoint. Supports multiple apps, OAuth 2.0, OAuth 1.0a, and app-only auth.

xurl — Agent Skill Reference

xurl is a CLI tool for the X API. It supports both shortcut commands (human/agent‑friendly one‑liners) and raw curl‑style access to any v2 endpoint. All commands return JSON to stdout.

---

Prerequisites

This skill requires the xurl CLI utility: https://github.com/xdevplatform/xurl.

Before using any command you must be authenticated. Run xurl auth status to check.

Secret Safety (Mandatory)

• Never read, print, parse, summarize, upload, or send anything under ~/.xurl/ (or copies of it) to the LLM context.
• ~/.xurl/keys.yml contains XChat private encryption keys — the strictest no-read rule applies.
• Never pass --pin inline in agent/LLM sessions (xurl chat keys restore --pin ... leaks the recovery PIN to context and shell history). Run xurl chat keys restore without the flag so the PIN is prompted without echo, or have the user run it manually.
• Never ask the user to paste credentials/tokens into chat.
• The user must fill ~/.xurl/auth.yml with required secrets manually on their own machine.
• Do not recommend or execute auth commands with inline secrets in agent/LLM sessions.
• Warn that using CLI secret options in agent sessions can leak credentials (prompt/context, logs, shell history).
• Never use --verbose / -v in agent/LLM sessions; it can expose sensitive headers/tokens in output.
• Never run xurl token in agent/LLM sessions: it prints a live OAuth2 access token to stdout, which is a credential and must not enter the LLM context.
• xurl mcp is for configuring an MCP client (it bridges stdio↔HTTP and injects the bearer token); it is not something to invoke directly from an agent/LLM session.
• Sensitive flags that must never be used in agent commands: --bearer-token, --consumer-key, --consumer-secret, --access-token, --token-secret, --client-id, --client-secret.
• To verify whether at least one app with credentials is already registered, run: xurl auth status.

Register an app (recommended)

App credential registration must be done manually by the user outside the agent/LLM session. After credentials are registered, authenticate against the app that holds those credentials:

xurl auth oauth2 --app APP_NAME

You can also run xurl auth default APP_NAME first and then use xurl auth oauth2.

On a remote/headless machine (no reachable browser callback), add --headless: xurl auth oauth2 --app APP_NAME --headless prints the authorization URL and reads the pasted redirect URL (or code) back, so no localhost callback is needed.

For multiple pre-configured apps, switch between them:

xurl auth default prod-app          # set default app
xurl auth default prod-app alice    # set default app + user
xurl --app dev-app /2/users/me      # one-off override
xurl auth apps redirect-uri get prod-app
xurl auth apps redirect-uri set prod-app http://localhost:8080/callback

Other auth methods

Examples with inline secret flags are intentionally omitted. If OAuth1 or app-only auth is needed, the user must run those commands manually outside agent/LLM context.

Tokens are persisted to ~/.xurl/auth.yml in YAML format (a legacy single-file ~/.xurl is migrated automatically). Each app has its own isolated tokens and may also store a redirect_uri. REDIRECT_URI in the environment still takes precedence over the stored app value. Do not read this file (or anything under ~/.xurl/) through the agent/LLM. Once authenticated, every command below will auto‑attach the right Authorization header.

Encrypted Chat (XChat)

xurl chat is an end-to-end encrypted XChat client: encryption and decryption happen locally via the chat-xdk crypto library, so the server only sees ciphertext. Requires OAuth2 user auth with dm.read + dm.write scopes, and is available on macOS (Intel/Apple Silicon) and Linux amd64 — release binaries include it there; elsewhere (Windows, Linux arm64/i386) xurl chat prints a stub that says so.

Keys come from another XChat client — xurl never generates or registers encryption keys. The account must already have keys (e.g. from the X app); bring them to this machine once with restore (Juicebox PIN recovery) or import (an exported key blob). Private keys are stored in ~/.xurl/keys.yml (mode 600) — never read that file into LLM context.

A conversation is addressed by @username, a bare user id, or a conversation id (1:1 ids look like 123-456; group ids look like g123). Every command accepts -u USERNAME to act as a specific authenticated account.

# 1. Keys — one-time setup (xurl never generates/registers keys)
xurl chat keys status                # local key presence/fingerprint + registered versions
xurl chat keys restore               # recover from Juicebox; prompts for the PIN (no echo)
xurl chat keys import                # paste an exported private-key blob (no echo)

# 2. Browse the inbox
xurl chat conversations              # pretty list; decrypts group names when keys are present
xurl chat conversations --json       # raw JSON

# 3. Read history (oldest first; auto-marks the conversation read)
xurl chat read @someuser
xurl chat read g1234567890 -n 50     # -n = how many events to fetch (max 100)
xurl chat read @someuser --json      # decrypted events as JSON (each has id, sequence_id, content)
xurl chat read @someuser --no-mark-read   # read without sending a read receipt

# 4. Send (a new 1:1 sets up its key automatically; both sides need keys)
xurl chat send @someuser "hey, encrypted!"
xurl chat send @someuser "look" --file ./photo.png       # attach an encrypted file
xurl chat send @someuser "agreed" --reply-to SEQUENCE_ID # threaded reply (id from `read --json`)
# send auto-sends a typing indicator first and marks read after;
# suppress with --no-typing / --no-mark-read

# 5. Attachments — inbound messages show "📎 attachment <media_hash_key>"
xurl chat download @someuser MEDIA_HASH_KEY -o out.png   # download + decrypt

# 6. Live tail (poll loop; Ctrl-C to stop; auto-marks new messages read)
xurl chat listen @someuser
xurl chat listen g1234567890 --interval 5

# 7. Read receipts / typing (also happen automatically on read/send)
xurl chat mark-read @someuser        # mark read up to the newest message
xurl chat typing @someuser           # send a typing indicator

# 8. Group key management (writes visible to all participants)
xurl chat add-members g123 @newuser  # add a member (rotates the key; prompts, or --yes)
xurl chat rotate g123                 # rotate the conversation key; prompts, or --yes
# Rotate when a key may be exposed, or to grant a member whose keys were
# registered after the last rotation access going forward. Future messages
# only — old history stays readable only to holders of the old key versions.

Notes for agents:

• Messages whose authorship signature cannot be verified are rejected by default and surface as stderr decrypt warnings; unsigned messages that still render carry a red [unverified] marker — treat those with suspicion.
• Messages with attachments render a 📎 attachment <media_hash_key> marker; pass that hash key to xurl chat download CONV <media_hash_key> to fetch and decrypt the file. Replies show a ↩ prefix.
• read and listen mark the conversation read automatically (a read receipt visible to other participants); send also marks read and sends a typing indicator first. These are writes — pass --no-mark-read / --no-typing to suppress them (e.g. to read without signaling). The standalone mark-read and typing commands remain for scripted/explicit use.
• Decrypt warnings for individual events go to stderr and are non-fatal; the rest of the conversation still renders.
• If a command reports missing keys, do not attempt to generate or register any — tell the user to run xurl chat keys restore (or import) themselves.
• chat rotate and chat add-members are writes visible to every participant's clients; never run them without explicit user intent, and prefer letting the user confirm the prompt over passing --yes.

Media Upload

# Upload a file (auto‑detects type for images/videos)
xurl media upload photo.jpg
xurl media upload video.mp4

# Specify type and category explicitly
xurl media upload --media-type image/jpeg --category tweet_image photo.jpg

# Check processing status (videos need server‑side processing)
xurl media status MEDIA_ID
xurl media status --wait MEDIA_ID    # poll until done

# Full workflow: upload then post
xurl media upload meme.png           # response includes media id
xurl post "lol" --media-id MEDIA_ID

---

Global Flags

These flags work on every command:

Flag	Short	Description
--app		Use a specific registered app for this request (overrides default)
--auth		Force auth type: oauth1, oauth2, or app
--username	-u	Which OAuth2 account to use (if you have multiple)
--verbose	-v	Forbidden in agent/LLM sessions (can leak auth headers/tokens)

---

Raw API Access

The shortcut commands cover the most common operations. For anything else, use xurl's raw curl‑style mode — it works with any X API v2 endpoint:

# GET request (default)
xurl /2/users/me

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

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

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

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

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

---

Streaming

Streaming endpoints are auto‑detected. Known streaming endpoints include:

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

You can force streaming on any endpoint with -s:

xurl -s /2/some/endpoint

---

Output Format

All commands return JSON to stdout, pretty‑printed with syntax highlighting. The output structure matches the X API v2 response format. A typical response looks like:

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

Errors are also returned as JSON:

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

---

xurl auth oauth2                       # authenticates on staging app

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

---

Error Handling

• Non‑zero exit code on any error.
• API errors are printed as JSON to stdout (so you can still parse them).
• Auth errors suggest re‑running xurl auth oauth2 or checking your tokens.
• If a command requires your user ID (like, repost, bookmark, follow, etc.), xurl will automatically fetch it via /2/users/me. When that endpoint is unreliable, use --username USERNAME or authenticate with xurl auth oauth2 --app APP_NAME USERNAME so xurl can fall back to username lookup.
• If X returns client-forbidden / client-not-enrolled after successful auth, check the app’s X developer-console package and environment. In current testing, moving the app to Pay-per-use and Production fixed /2/* read failures without changing local xurl auth data.

---

Notes

• Rate limits: The X API enforces rate limits per endpoint. If you get a 429 error, wait and retry. Write endpoints (post, reply, like, repost) have stricter limits than read endpoints.
• Scopes: OAuth 2.0 tokens are requested with broad scopes. If you get a 403 on a specific action, your token may lack the required scope — re‑run xurl auth oauth2 to get a fresh token.
• Token refresh: OAuth 2.0 tokens auto‑refresh when expired. No manual intervention needed.
• Multiple apps: Each app has its own isolated credentials, tokens, and optional stored redirect_uri. Configure credentials manually outside agent/LLM context, then switch with xurl auth default or --app.
• Redirect URI precedence: The effective redirect URI resolves from REDIRECT_URI in the environment first, then the app's stored redirect_uri in ~/.xurl/auth.yml, then the built-in default.
• Redirect URI management: Use xurl auth apps redirect-uri get [NAME], xurl auth apps redirect-uri set NAME URI, or xurl auth apps update NAME --redirect-uri URI to inspect and manage the stored per-app callback value.
• X platform enrollment: A successful OAuth callback does not guarantee /2/* reads will work. If you see client-not-enrolled, verify the app is in the correct X package/environment. Current confirmed fix: Apps -> Manage apps -> Move to package -> choose Pay-per-use, then move the app to Production.
• Multiple accounts: You can authenticate multiple OAuth 2.0 accounts per app and switch between them with --username / -u or set a default with xurl auth default APP USER.
• Default user: When no -u flag is given, xurl uses the default user for the active app (set via xurl auth default). If no default user is set, it uses the first available token.
• Token storage: ~/.xurl is a directory; ~/.xurl/auth.yml holds each app's credentials and tokens. Never read or send anything under ~/.xurl/ to LLM context.
• Chat key storage: ~/.xurl/keys.yml holds XChat private encryption keys per user (mode 600). Losing it means losing the ability to decrypt on this machine (recoverable via xurl chat keys restore if a Juicebox PIN backup exists). Never read or send this file to LLM context.
• Chat key registration: xurl performs none — no public-key registration and no Juicebox writes. Only keys already registered by another XChat client can be restored or imported; unregistered keys are rejected.
• Access tokens: xurl token prints a valid (refreshed) OAuth2 access token for the active app to stdout, refreshing and persisting it if expired. It never opens a browser. The output is a secret — use it only in the user's own scripts, never in agent/LLM sessions.
• MCP bridge: xurl mcp [URL] bridges a stdio MCP client to a remote Streamable HTTP MCP server (default https://api.x.com/mcp), injecting Authorization: Bearer <token> and refreshing the token automatically. On first run with no cached token it opens the browser for a one-time OAuth2 login using the CLIENT_ID/CLIENT_SECRET from its environment (the handshake waits for it, so set a generous startup_timeout_sec); on a headless host, authenticate out-of-band first with xurl auth oauth2 --headless. Configure it in an MCP client via the npm launcher: {"command":"npx","args":["-y","@xdevplatform/xurl","mcp","https://api.x.com/mcp"],"env":{"CLIENT_ID":"...","CLIENT_SECRET":"..."},"startup_timeout_sec":300}.
