aioscam 0.1.8

Async framework for Max messenger bots (aiogram-style)

AioScam

Async Python framework for building Max messenger bots, inspired by aiogram architecture.

Version

v0.1.8 — Latest (2026-06-15)

What's new in v0.1.8

• ✅ send_action() — fixed API path (/chats/{chat_id}/actions) and SenderAction values
• ✅ SendCallback method object — answer callback queries via bot.send_callback()
• ✅ send_message(autosplit=True) — opt-in splitting of messages >4000 chars, keyboard on last chunk
• ✅ StateGuard callbacks — state_guard_callbacks now accepts magic_filter.F expressions (.startswith(), .contains(), .regexp(), & | ~) alongside exact-match strings
• ✅ Parallel update processing — asyncio.create_task() per update in start_polling()
• ✅ Streaming uploads/downloads — no full in-memory reads for media
• ✅ 569/569 tests passing

Features

• 🚀 Fully async — asyncio + aiohttp
• 🎯 aiogram-style API — familiar decorators and patterns
• 🔄 Router system — modular, nestable
• 🎭 Magic Filters — F.text, F.callback.payload, F.message.body.text
• 🔧 Middleware — request/response pipeline
• 📦 FSM — State, StatesGroup, MemoryStorage
• 🛡️ StateGuard — blocks unauthorized commands during active FSM
• 🖼️ Media — upload/download images, video, audio, documents
• 📱 Contact & Location — inline buttons for phone and geolocation
• 📝 Formatting — Markdown and HTML
• 🔗 Deep links — create_deep_link, parse_deep_link, StartCommand filter
• 🌍 I18n — JSON-based translations, auto locale from user_locale
• 📋 Bot Commands — set_my_commands(), set_bot_info()
• 🗑️ Message Management — delete, pin, edit
• 🌐 Webhook — aiohttp, FastAPI, Litestar
• 📡 Polling — long-polling with exponential backoff
• 🛡️ Rate Limiter — token bucket, 429 retry, exponential backoff
• 🔒 Security — webhook secret token, circular router detection
• 📦 Python 3.9–3.12

Installation

git clone https://github.com/alex-di-96/aioscam.git
cd aioscam
pip install -e .

pip install aioscam[fastapi]   # FastAPI webhook
pip install aioscam[litestar]  # Litestar webhook
pip install aioscam[dev]       # pytest, ruff, mypy

Quick Start

import asyncio
from aioscam import Bot, Dispatcher, Router
from aioscam.filters import Command, F

dp = Dispatcher()
router = Router()

@router.message_created(Command("start"))
async def cmd_start(event):
    await event.answer("Hello! Send me anything.")

@router.message_created()
async def echo(event):
    await event.answer(event.text)

dp.include_router(router)

async def main():
    bot = Bot()  # token from MAX_BOT_TOKEN env
    await dp.start_polling(bot)

asyncio.run(main())

Media

from aioscam import InputMedia, InputMediaBuffer, UploadType

# Send from file path (type auto-detected from extension)
await bot.send_photo(chat_id=cid, user_id=uid, photo="photo.jpg")
await bot.send_video(chat_id=cid, user_id=uid, video="video.mp4", caption="Watch!")
await bot.send_document(chat_id=cid, user_id=uid, document="report.pdf")
await bot.send_audio(chat_id=cid, user_id=uid, audio="song.mp3")

# Auto-detect type
await bot.send_media(chat_id=cid, user_id=uid, media="anyfile.ext")

# From bytes buffer (no file on disk)
data = open("photo.jpg", "rb").read()
await bot.send_photo(chat_id=cid, user_id=uid, photo=data)

# Download incoming media into memory
image_bytes = await bot.download_file_bytes(url, token)

# Download to disk with unique temp name
path = Bot.make_temp_path(".jpg")  # /tmp/aioscam_20260528_143022_847291.jpg
await bot.download_file(path, url, token)

FSM

from aioscam.fsm import State, StatesGroup

class Registration(StatesGroup):
    waiting_name = State()
    waiting_age = State()
    waiting_email = State()
    waiting_phone = State()

@router.message_created(Command("register"))
async def start(event, state):
    await state.set_state(Registration.waiting_name)
    await event.answer("Step 1/4: Enter your name:")

@router.message_created(StateFilter(Registration.waiting_name))
async def name(event, state):
    await state.update_data(name=event.text)
    await state.set_state(Registration.waiting_age)
    await event.answer("Step 2/4: Enter your age:")

Rate Limiter

from aioscam import Bot
from aioscam.limiter import RateLimitConfig

bot = Bot(rate_limit=RateLimitConfig.strict())   # 5 req/s, burst 10
bot = Bot(rate_limit=RateLimitConfig.relaxed())  # 30 req/s, burst 50
