boostylib 1.0.1

Async Python library for Boosty.to API

boostylib

Async Python library for the Boosty.to API. Manage subscriptions, posts, donations, and automate responses — all from Python.

---

Features

• Fully async (async/await) with httpx + synchronous wrapper (SyncBoostyClient)
• Automatic token refresh with pluggable storage backends
• Pydantic v2 models with strict validation
• Subscriber data with email, payments, and status
• Fluent PostBuilder for creating posts with access control (subscription levels, donations)
• Two-step post creation (draft → publish) matching Boosty's real API flow
• Subscription level CRUD (create, list, delete)
• Target/goal management (money and subscriber goals)
• Decorator-based event system with real polling detectors for new subscribers, comments, and cancellations
• Auto-reply to comments with threading support
• Media uploads (images, files, video, audio)
• In-memory caching with TTL and pluggable backends (CacheBackend protocol)
• Configurable retry with exponential backoff and rate limiting
• Middleware pipeline for custom request/response processing
• Browser-like HTTP fingerprint for write operations
• PEP 561 typed — full mypy --strict support

Installation

pip install boostylib

or with uv:

uv add boostylib

Quick Start

Getting Your Tokens

1. Log in to boosty.to
2. Open DevTools (F12) → Application → Local Storage → https://boosty.to
3. Copy the auth object (access_token, refresh_token, expires_at) and _clentId (this is the device_id)

Verify a Subscription

from boostylib import BoostyClient

async with BoostyClient(access_token="your_token") as client:
    status = await client.subscriptions.verify_subscription("my_blog", "user_id")

    if status.is_subscribed:
        print(f"Subscribed: {status.level.name} (paid={status.is_paid})")
    else:
        print("Not subscribed")

Get Subscriber Emails and Payments

async with BoostyClient(access_token="...") as client:
    subscribers = await client.subscriptions.get_subscribers("my_blog")
    for sub in subscribers:
        print(f"{sub.name}: {sub.email}, payments={sub.payments}, active={sub.is_active}")

    # Async iterator for all subscribers
    async for sub in client.subscriptions.iter_subscribers("my_blog"):
        if sub.is_paid:
            print(f"Paid: {sub.name} ({sub.email}) — {sub.payments} RUB")

Create a Post for Premium Subscribers

from boostylib import BoostyClient, AuthCredentials
from boostylib.builders import PostBuilder

creds = AuthCredentials(
    access_token="...",
    refresh_token="...",
    device_id="...",
)

async with BoostyClient(credentials=creds) as client:
    levels = await client.subscriptions.get_levels("my_blog")
    premium = next(l for l in levels if l.name == "Premium")

    post = (
        PostBuilder()
        .title("Premium Only Content")
        .text("This is exclusive content for premium subscribers.")
        .image(url="https://example.com/img.png")
        .access_level(level_id=str(premium.id))
        .teaser("Subscribe to Premium to unlock this post!")
        .build()
    )

    created = await client.posts.create_post("my_blog", post)
    print(f"Post created: {created.id}")

Create a Post Unlocked by Donation

from boostylib.builders import PostBuilder

post = (
    PostBuilder()
    .title("Exclusive for Donors")
    .text("Available to anyone who donated 500+ RUB")
    .minimum_donation(amount=500, currency="RUB")
    .build()
)

Auto-Respond to Events

from boostylib import BoostyClient, EventType

client = BoostyClient(access_token="...", blog_username="my_blog")

@client.on(EventType.NEW_SUBSCRIPTION)
async def on_subscribe(event):
    await client.comments.create_comment(
        event.blog_username,
        event.welcome_post_id,
        f"Welcome to {event.level.name}, {event.user.name}!",
    )

@client.on(EventType.NEW_COMMENT)
async def on_comment(event):
    await client.comments.create_comment(
        event.blog_username, event.post_id,
        f"Thanks for commenting, {event.user.name}!",
        reply_to=str(event.comment_id),
    )

@client.on(EventType.SUBSCRIPTION_CANCELLED)
async def on_cancel(event):
    print(f"Lost subscriber: {event.user.name}")

async with client:
    await client.start_polling()

Synchronous Usage

No async/await needed — works in scripts, Django views, Jupyter notebooks:

from boostylib.sync import SyncBoostyClient

with SyncBoostyClient(access_token="...") as client:
    user = client.users.get_current_user()
    print(user.name)

    subscribers = client.subscriptions.get_subscribers("my_blog")
    for sub in subscribers:
        print(f"{sub.name}: {sub.email}")

    post = PostBuilder().title("Hello").text("World").free().build()
    client.posts.create_post("my_blog", post)

Upload a File

from pathlib import Path
from boostylib import BoostyClient
from boostylib.builders import PostBuilder

async with BoostyClient(access_token="...") as client:
    media = await client.media.upload_file(
        Path("./project_source.zip"),
        filename="project_source.zip",
    )

    post = (
        PostBuilder()
        .title("Project Sources")
        .text("Download the full source archive:")
        .file(media_id=media.id, filename=media.filename)
        .access_level(level_id="premium_level_id")
        .build()
    )
    await client.posts.create_post("my_blog", post)

Manage Subscription Levels

async with BoostyClient(access_token="...") as client:
    # Create a level
    level = await client.subscriptions.create_level(
        "my_blog", name="VIP", price=1000, description="Exclusive access"
    )
    print(f"Created: {level.name} (id={level.id})")

    # Delete a level
    await client.subscriptions.delete_level("my_blog", level.id)

Manage Goals/Targets

from boostylib.enums import TargetType

async with BoostyClient(access_token="...") as client:
    # Money goal
    goal = await client.targets.create_target(
        "my_blog", description="New equipment", target_sum=50000, target_type=TargetType.MONEY,
    )

    # Subscriber goal
    sub_goal = await client.targets.create_target(
        "my_blog", description="1000 subscribers!", target_sum=1000, target_type=TargetType.SUBSCRIBERS,
    )

    # Read back
    fetched = await client.targets.get_target(goal.id)
    print(f"{fetched.description}: {fetched.current_sum}/{fetched.target_sum}")

    # Clean up
    await client.targets.delete_target(goal.id)

Configuration

All settings can be configured via environment variables, a TOML file, or programmatically.

Environment Variables

export BOOSTY_ACCESS_TOKEN=...
export BOOSTY_REFRESH_TOKEN=...
export BOOSTY_DEVICE_ID=...
export BOOSTY_TIMEOUT=30
export BOOSTY_MAX_RETRIES=3
export BOOSTY_POLL_INTERVAL=60
export BOOSTY_DEBUG=true
export BOOSTY_CACHE_ENABLED=true

TOML Config (boosty.toml)

timeout = 30.0
max_retries = 3
poll_interval = 60.0
rate_limit_requests = 60
cache_enabled = true
cache_ttl_blog = 300
cache_ttl_levels = 600
debug = false

Programmatic

from boostylib import BoostyClient, BoostySettings

settings = BoostySettings(timeout=10.0, max_retries=5, debug=True)
client = BoostyClient(settings=settings, access_token="...")

Caching

Built-in in-memory cache with configurable TTL:

from boostylib import BoostyClient, BoostySettings

# Cache enabled by default (MemoryCache)
client = BoostyClient(access_token="...")

# Disable cache
client = BoostyClient(access_token="...", settings=BoostySettings(cache_enabled=False))

# Manual cache operations
await client.cache.clear()
await client.cache.delete("blog:my_blog:info")
await client.cache.invalidate_pattern("blog:my_blog:")

Custom cache backend (e.g. Redis):

from boostylib.cache import CacheBackend

class RedisCache:
    async def get(self, key: str) -> bytes | None: ...
    async def set(self, key: str, value: bytes, *, ttl: int | None = None) -> None: ...
    async def delete(self, key: str) -> None: ...
    async def clear(self) -> None: ...

client = BoostyClient(access_token="...", cache=RedisCache())

Token Storage

Backend	Description
MemoryTokenStorage	In-memory, for tests and one-shot scripts (default)
FileTokenStorage	Persists to ~/.boosty/auth.json with secure file permissions

class RedisTokenStorage:
    async def load(self) -> TokenPair | None: ...
    async def save(self, tokens: TokenPair) -> None: ...
    async def clear(self) -> None: ...

Middleware

from boostylib import BoostyClient
from boostylib.http.middleware import BaseMiddleware
import httpx

class LoggingMiddleware(BaseMiddleware):
    async def on_request(self, request: httpx.Request) -> httpx.Request:
        print(f"-> {request.method} {request.url}")
        return request

    async def on_response(self, response: httpx.Response) -> httpx.Response:
        print(f"<- {response.status_code}")
        return response

client = BoostyClient(access_token="...", middleware=[LoggingMiddleware()])
