Bilibili All-in-One Skill

A comprehensive Bilibili toolkit that integrates hot trending monitoring, video downloading, video watching/playback, subtitle downloading, and video publishing capabilities into a single unified skill.

⚠️ Optional Environment Variables:
BILIBILI_SESSDATA
,
BILIBILI_BILI_JCT
(optional),
BILIBILI_BUVID3
(optional),
BILIBILI_PERSIST

📦 Install:
pip install -r requirements.txt
(all standard PyPI packages: httpx, aiohttp, beautifulsoup4, lxml, requests)

Installation

Requirements

Python >= 3.8
ffmpeg (optional, for merging video/audio streams)

Install Dependencies

pip install -r requirements.txt

Dependencies

```
httpx >= 0.24.0
```
```
aiohttp >= 3.8.0
```
```
beautifulsoup4 >= 4.12.0
```

lxml >= 4.9.0

Configuration

Some features (downloading high-quality videos, publishing, etc.) require Bilibili authentication. You can provide credentials in three ways:

1. Environment Variables

export BILIBILI_SESSDATA="your_sessdata"
export BILIBILI_BILI_JCT="your_bili_jct"
export BILIBILI_BUVID3="your_buvid3"

2. Credential File

Create a JSON file (e.g.,

credentials.json

{
  "sessdata": "your_sessdata",
  "bili_jct": "your_bili_jct",
  "buvid3": "your_buvid3"
}

3. Direct Parameters

Pass credentials directly when initializing:

from main import BilibiliAllInOne
app = BilibiliAllInOne(
sessdata="your_sessdata",
bili_jct="your_bili_jct",
buvid3="your_buvid3",
)

4. Persistent Storage (Optional)

By default, credentials are kept in-memory only and are not saved to disk. To enable automatic persistence across sessions:

# Via environment variable
export BILIBILI_PERSIST=1

# Or via code
app = BilibiliAllInOne(persist=True)

When persistence is enabled:

Credentials are auto-saved to
```
.credentials.json
```
(with
```
0600
```
permissions) after initialization
On next startup, credentials are auto-loaded from this file

You can toggle persistence at runtime:

app.auth.persist = True

app.auth.persist = False

To delete the persisted file:
```
app.auth.clear_persisted()
```

How to get cookies: Log in to bilibili.com, open browser DevTools (F12) → Application → Cookies, and copy the values of
SESSDATA
,
bili_jct
, and
buvid3
.

⚠️ Security & Privacy

Credential Handling

This skill handles sensitive Bilibili session cookies. Please read the following carefully:

Concern	Detail
What credentials are needed?	`SESSDATA` , `bili_jct` , `buvid3` — Bilibili full browser session cookies (not limited API keys). Providing them grants broad access to your Bilibili account.
Which features require authentication?	Publishing (upload/edit/schedule/draft), downloading 1080p+/4K quality videos
Which features work WITHOUT credentials?	Hot monitoring, standard-quality downloads, subtitle listing, danmaku fetching, stats viewing
Where are credentials sent?	To official Bilibili API endpoints ( `api.bilibili.com` , `member.bilibili.com` ) over HTTPS only
Are credentials persisted to disk?	NO by default — credentials stay in memory. Set `persist=True` or `BILIBILI_PERSIST=1` to opt-in to automatic persistence (saved to `.credentials.json` with `0600` permissions). You can also manually call `auth.save_to_file()`
File permissions for saved credentials	`0600` (owner read/write only) — restrictive by default

Best Practices

🧪 Use a test account — Do NOT provide your primary Bilibili account cookies for evaluation/testing purposes. These are full session cookies that grant broad account access (not limited API keys).
🔒 Prefer in-memory credentials — Pass credentials via environment variables or direct parameters rather than saving to a file. Only enable
```
persist=True
```
if you need credentials to survive across sessions.
📁 If you enable persistence — Credentials are saved with
```
0600
```
permissions. Use
```
auth.clear_persisted()
```
or
```
auth.persist = False
```
to remove the file when no longer needed.
🐳 Run in isolation — When possible, run this skill in an isolated container/environment and inspect network traffic.
🌐 Verify network traffic — All HTTP requests go to Bilibili's official domains only. You can verify by monitoring outbound connections.
❌ No exfiltration — This skill does NOT send credentials to any third-party service, analytics endpoint, or telemetry server.
🔑 Credential scope —
```
SESSDATA
```
and
```
bili_jct
```
are full session cookies. They are NOT scoped/limited API keys. Treat them with the same care as your account password.

Network Endpoints Used

Domain	Purpose
`api.bilibili.com`	Video info, stats, hot lists, subtitles, danmaku, playback URLs
`member.bilibili.com`	Video publishing (upload, edit)
`upos-sz-upcdnbda2.bilivideo.com`	Video file upload CDN
`www.bilibili.com`	Web page scraping fallback

Credential Requirement by Module

Module	Auth Required?	Notes
🔥 Hot Monitor	❌ No	All public APIs
⬇️ Downloader	⚠️ Optional	Required only for 1080p+ / 4K quality
👀 Watcher	❌ No	Public stats APIs
📝 Subtitle	❌ No	Public subtitle APIs
▶️ Player	⚠️ Optional	Required for high-quality playback URLs
📤 Publisher	✅ Required	All operations need `SESSDATA` + `bili_jct`
