TikTok — Profile Videos

TikTok username → user profile info + paginated video list with full metadata

Language

All process output to user (progress updates, process notifications) follows the user's language.

Objective

Extract the video list and profile metadata for a given TikTok user using the /api/post/item_list/ endpoint triggered by navigating to their profile page.

Prerequisites

• Browser is open and can access https://www.tiktok.com
• No login required for public profiles
• Browser must use a non-HK proxy (TikTok has shut down in Hong Kong)

Pre-execution Checks

1. Tool Readiness

If browser-act has been confirmed available in the current session → skip this step.

Invoke browser-act via Skill tool to load usage. If installation or configuration issues arise, follow its guidance to resolve then retry.

Capability Components

This Skill's operational boundary = what the user can manually do in their browser. It only reads data already displayed to the user on the page, never bypassing authentication or access controls. JS code is encapsulated in Python files under the scripts/ directory, invoked via eval "$(python scripts/xxx.py {params})". $(...) is bash syntax; it is recommended to use the bash tool for execution.

Network Capture: Profile video list (parameters injected via URL navigation)

/api/post/item_list/ requires TikTok's dynamic signing and the user's secUid (internal ID). Navigate to the profile page — TikTok's JS resolves the secUid and triggers the signed request automatically:

1. navigate https://www.tiktok.com/@{username}
2. wait stable
3. network requests --type xhr,fetch --filter "post/item_list"
4. network request <id>

Endpoint characteristic: URL contains /api/post/item_list/ with secUid={secUid}&cursor=0

Note: The secUid is a long internal identifier (e.g., MS4wLjABAAAA-VASjiXTh7wDDyXvjk10VFhMWUAoxr8bgfO1kAL1-9s) visible in the captured request URL — record it for pagination requests.

Error handling: If no matching request appears, verify the profile page loaded (screenshot). Private accounts return an empty itemList. If the page shows a region block, switch to a non-HK proxy browser.

To build the webVideoUrl for each item: https://www.tiktok.com/@{item.author.uniqueId}/video/{item.id}

Profile info is available from the first item's author and authorStats fields: followerCount, following, heart total, video count, bio, verified status.

Network Capture: Profile video list pagination (page 2+)

After reading page 1, scroll down to load more videos:

1. scroll down
2. wait stable
3. network requests --type xhr,fetch --filter "post/item_list"
4. Find the new request (cursor value changed from the previous page's cursor)
5. network request <id>

Termination: hasMore is false in response, or itemList is empty.

Pagination

DOM Pagination: Scroll triggers new post/item_list requests with timestamp-based cursor. Each page returns 16 items. Termination: hasMore === false or empty itemList.

Success Criteria

itemList.length >= 1 and first item has non-null id, stats.playCount, author.uniqueId, authorStats.followerCount

Known Limitations

• Requires non-HK proxy (TikTok shut down in Hong Kong)
• post/item_list requires dynamic signing + secUid resolved by TikTok's JS — always use navigate + network capture
• Private accounts return empty itemList
• authorStats.heartCount may overflow to negative for accounts with very high like counts — use authorStats.heart instead
• followers/following lists are not available via this capability (separate scraper needed, requires login)

Execution Efficiency

• Batch orchestration: Loop through multiple usernames serially in one session; add 2–3s between profile navigations.
• Test before batch execution: Test with 1 username first before running the full list.
• Error resumption: Save results profile-by-profile; resume from the failed username on error.

Experience Notes

Path: {working-directory}/browser-act-skill-forge-memories/tiktok-scraper-tiktok-profile-videos.memory.md

Before execution: If the file exists, read it first — it records unexpected situations from past executions; adjust strategy accordingly.

After execution: If an unexpected situation occurs (strategy failed, page redesigned, anti-scraping upgraded), append a line: {YYYY-MM-DD}: {what happened} → {conclusion}

Normal execution does not write to the file.
