What this is

xiaoyuzhou is a small command-line tool that lets any agent (or human) read a user's Xiaoyuzhou FM podcast data by composing ordinary shell commands — pipe into jq, filter by date, project fields, page through history. It prints JSON to stdout and uses exit codes for success/failure, so an agent never has to parse prose or swallow a 200 KB blob into its context just to get a title.

• 我的订阅 / subscribed podcasts
• 单集列表 / a podcast's episodes — auto-paginated, with inclusive --since / --until date windows
• 单集详情 + shownotes
• 官方字幕 / official transcript (one-shot download + parse, or just the signed URL)
• 搜索播客 / 单集 (search podcasts or episodes)
• 播放历史 / play history

All commands are read-only by design. No subscribe / unsubscribe / comment / mark-played — an agent can recommend but never act on the user's behalf without explicit human approval.

> Why a CLI and not an MCP server? This started life as an MCP server. For a browse/filter/paginate read tool, a CLI turned out to be the more agent-friendly surface: it composes with jq/grep/head, lets the caller pull only the fields it needs (no fixed fat payload, no token-limit cliff), and pages through history natively. The auth/self-heal core (xiaoyuzhou/client.py) is unchanged — only the surface is.

When to use this

Whenever the user mentions any of these (Chinese or English):

• 小宇宙 / 小宇宙 FM / 小宇宙播客 / Xiaoyuzhou / Xiaoyuzhoufm
• 我的播客订阅 / 订阅了什么播客 / podcast subscriptions
• 某天/最近更新了哪些播客 / 新单集 / new episodes on a date
• 播客字幕 / 播客转文字 / podcast transcript
• 搜播客 / 找播客 / search podcast/episode
• 我最近听了什么 / 播放历史 / play history

For Apple Podcasts / Spotify / generic podcasts, this is NOT the right tool — it only talks to Xiaoyuzhou.

Commands

xyz subs                                   # your subscribed podcasts
xyz episodes  [--limit N]             # newest N episodes (auto-paginated)
xyz episodes  --since 2026-05-28 --until 2026-05-29   # full date window
xyz episode                           # one episode's detail
xyz transcript  --media-id  [--format plain|timestamped|segments] [--text]
xyz transcript-url  --media-id   # signed URL only, no download
xyz search "关键词" [--kind PODCAST|EPISODE] [--limit N]
xyz history [--limit N]
xyz send-code                       # SMS login, step 1
xyz login                     # SMS login, step 2 (saves token)

Shared output flags on list/detail commands:

• --jsonl — one JSON object per line (ideal for | jq / | grep)
• --full — keep shownotes_html (dropped by default to stay lean)
• --fields a,b,c — project to just those keys

Why the date window matters

The upstream /v1/episode/list caps each page at ~15 episodes and exposes a loadMoreKey cursor. xyz episodes follows that cursor automatically: with --since it keeps paging back until the window is fully covered — so a high-frequency feed that posts several episodes a day is never silently truncated at 15.

# Which of my subscriptions updated on 2026-05-28? (title + podcast only)
for pid in $(xyz subs --fields pid --jsonl | jq -r .pid); do
  xyz episodes "$pid" --since 2026-05-28 --until 2026-05-28 \
      --jsonl --fields podcast_title,title
done

Quick start

git clone https://github.com/r266-tech/xiaoyuzhou.git
cd xiaoyuzhou
pip install -e .          # installs the `xyz` / `xiaoyuzhou` commands
# …or run without installing:  ./run subs

Login (one time, SMS)

xyz send-code 13800138000
xyz login 13800138000 123456
# or the interactive helper:  python scripts/login.py --phone 13800138000

Token is stored at ~/cc-workspace/state/xiaoyuzhou/token.json (chmod 0600). Override with XIAOYUZHOU_STATE_DIR if you don't use the cc-workspace convention. The token is never part of the repo (.gitignore excludes state/ and token.json).

Verify

xyz subs                  # should list your podcasts
python scripts/verify.py  # direct client smoke test

Design notes

• Composable surface: JSON to stdout, exit codes for success/failure, --fields/--jsonl so callers pull only what they need. No fat fixed payloads.
• Real pagination: list_episodes follows loadMoreKey (safety ceiling 100 pages); --since controls how far back to go.
• Agent-first schemas: shallow dicts, snake_case, ISO 8601 timestamps — no {data:{data:[...]}} wrappers.
• Transparent auth: on 401 the client refreshes once and retries; callers never see auth state. 4xx during refresh clears the token (re-login needed); network errors leave state alone.
• Atomic token writes: fcntl.flock + uuid'd .tmp + os.replace; dir 0o700, file 0o600.
• Distributable: no hardcoded /Users/... paths, no homebrew assumptions; Intel Mac, Apple Silicon, Linux. Relocate state via $XIAOYUZHOU_STATE_DIR / $BABATA_STATE_DIR.
• Read-only on purpose: write endpoints exist upstream but are deliberately not exposed.

Gotchas

• Date windows are Beijing-local (UTC+8) — the API's pubDate is UTC, but the app (and any human) means Beijing days. --since/--until convert before comparing, so an episode posted 00:00–08:00 Beijing lands on the right day instead of the previous UTC day.
• RSS-bridged shows still have transcripts — for podcasts syndicated from external hosts (e.g. Ximalaya), media.id is the external playback URL and asking the transcript API about it returns no_subtitle. Xiaoyuzhou mirrors the audio and serves the transcript under the episode's native transcriptMediaId; the client's media_id prefers it automatically (identical to media.id for native shows).
• Android UA is required — the transcript CDN validates User-Agent strictly; _app_headers() already uses the correct Xiaomi MI 6 / Android 28 UA.
• get_episode is GET + query string; other authenticated endpoints are POST + JSON body (mirrors the app).
• history has no precise played-seconds — upstream only exposes is_played / is_finished.

Endpoint surface was originally mapped against the unofficial Go client MosesHe/xiaoyuzhoufm-mcp and the xyz-dl project — thanks to both.
