veretube-bot 0.1.2

Python bot library for veretube sync channels

veretube-bot

Python library for writing bots on sync 4.0 aka veretube channels.

Bots connect over socket.io for real-time events (chat, user list, playlist changes) and use a REST API for commands (queue media, kick/ban, manage emotes, read/write settings). Both surfaces are covered by this library.

Installation

pip install veretube-bot

Getting a token

Tokens are issued in the channel settings modal on the Bots tab. You need at least moderator rank to see it. Fill in a name and rank, click Issue Token, and copy the token immediately — it starts with cbt_ and is only shown once.

Quick start

from veretube_bot import Bot

bot = Bot(
    token="cbt_...",
    channel="mychannel",
    socket_url="http://your-server:1337",   # socket.io port (default 1337)
    api_url="http://your-server:8080/api/v1",  # HTTP port (default 8080)
)

@bot.on("chatMsg")
def on_chat(data):
    if data["msg"] == "!hello":
        bot.send_message("Hello!", to=data["username"])

    if data["msg"] == "!np":
        if bot.now_playing:
            bot.send_message(f"Now playing: {bot.now_playing['title']}")

@bot.on("changeMedia")
def on_media(data):
    print(f"Now playing: {data['title']}")

bot.run()  # connect and block until disconnected

Connection

Bot(
    token,       # str  — bot token starting with 'cbt_'
    channel,     # str  — channel name (lowercase, no '#')
    socket_url,  # str  — socket.io server URL (uses io.port, not the HTTP port)
    api_url,     # str  — REST API base URL, e.g. http://host:8080/api/v1
    reconnection=False,       # set True to reconnect automatically on drop
    reconnection_delay=3,     # seconds between reconnect attempts
)

Method	Description
bot.run()	Connect and block until disconnected
bot.connect()	Open the connection and wait until / namespace is ready
bot.wait()	Block until disconnected (call after connect())
bot.disconnect()	Close the connection

By default reconnection=False — the expectation is that an external process supervisor (systemd, supervisord, etc.) handles restarts. Pass reconnection=True for bots that should self-recover.

Event handling

Register handlers with @bot.on(event_name). Multiple handlers for the same event are all called. Exceptions in a handler are logged and skipped so one bad handler doesn't affect the others.

@bot.on("chatMsg")
def on_chat(data):
    print(data["username"], data["msg"])

@bot.on("userLeave")
def on_leave(data):
    print(f"{data['name']} left")

Socket events

Event	Payload	Description
connect	None	Socket connected
disconnect	reason string or None	Socket disconnected
connect_error	error object	Connection failed
login	{ success, name, guest }	Server accepted the token
chatMsg	{ username, msg, meta, time }	Chat message sent
pm	{ username, msg, meta }	Private message received
userlist	[{ name, rank, meta }, ...]	Full user list on join
addUser	{ name, rank, meta }	User joined

kick	{ reason }	Bot was kicked
announcement	{ title, text }	Server-wide announcement
updateEmote	{ name, image }	Emote added or changed
removeEmote	{ name }	Emote removed

meta.is_bot is True in chatMsg and userlist payloads for bots.

In-memory state

These are updated automatically from socket events before your handlers are called:

bot.users        # list of { name, rank, meta } — current user list
bot.now_playing  # { id, type, title, seconds, ... } or None
bot.playlist     # list of playlist items
bot.channel_opts # channel options dict

Look up a specific user:

user = bot.get_user("Alice")  # returns dict or None

Chat

bot.send_message("Hello!")
bot.send_message("Hey!", to="Alice")  # sends "Alice: Hey!"
bot.send_action("waves")              # sends "/me waves"
bot.send_pm("Alice", "Hello privately")

Playlist

bot.queue("dQw4w9WgXcQ", "yt")          # add to end (rank >= MOD)
bot.queue("dQw4w9WgXcQ", "yt", "next")  # add as next up
bot.skip()                               # skip to next item (rank >= MOD)
bot.skip_to(uid)                         # jump to specific uid (rank >= MOD)
bot.delete_item(uid)                     # remove by uid (rank >= ADMIN)
bot.shuffle_playlist()                   # shuffle (rank >= ADMIN)
bot.clear_playlist()                     # clear all (rank >= ADMIN)

Media types: yt YouTube, sc SoundCloud, tw Twitch stream, tc Twitch clip, vm Vimeo, dm Dailymotion, fi direct file URL, cu custom embed.

Moderation

bot.kick("BadUser")                    # rank >= MOD
bot.kick("BadUser", reason="Spamming")
bot.ban("BadUser")                     # rank >= ADMIN
bot.ban("BadUser", reason="Evading")
bot.unban("BadUser")                   # rank >= ADMIN
bot.set_rank("Alice", Rank.MOD)        # rank >= OWNER

Emotes

Emote endpoints read/write the database directly and work even when the channel is offline.

emotes = bot.get_emotes()             # list of { name, image, source }
bot.add_emote("KEKW", "https://...")  # rank >= OWNER
bot.update_emote("KEKW", image="https://...")
bot.update_emote("KEKW", new_name="KEKWait")
bot.delete_emote("KEKW")             # rank >= OWNER

Settings

settings = bot.get_settings()           # rank >= OWNER, channel must be active
bot.update_settings(pagetitle="Now Playing: Chill Beats")
bot.update_settings(allow_voteskip=False, afk_timeout=300)

Available setting keys: allow_voteskip, allow_dupes, voteskip_ratio, maxlength, playlist_max_duration_per_user, afk_timeout, enable_link_regex, chat_antiflood, chat_antiflood_burst, chat_antiflood_sustained, new_user_chat_delay, new_user_chat_link_delay, pagetitle, password, externalcss, externaljs, show_public, torbanned, block_anonymous_users, allow_ascii_control, playlist_max_per_user.

Direct REST access

Every REST endpoint is also accessible on bot.api if you need something not covered by the shortcuts:

playlist = bot.api.get_playlist()   # { items, currentIndex, locked }
bot.api.skip_to(uid)
bot.api.set_user_rank("Alice", 2)

Error handling

REST calls raise BotAPIError on failure:

from veretube_bot import Bot, BotAPIError

@bot.on("chatMsg")
def on_chat(data):
    if data["msg"].startswith("!add "):
        _, type, id = data["msg"].split(None, 2)
        try:
            bot.queue(id, type)
        except BotAPIError as e:
            bot.send_message(f"Error: {e}")  # e.status_code has the HTTP code

Rank constants

from veretube_bot import Rank

Rank.MOD      # 2
Rank.ADMIN    # 3
Rank.OWNER    # 4
Rank.CREATOR  # 5

A bot's effective rank is capped at the rank of the user who issued its token.
