How do I get all the videos from a Douyin account?

You want a competitor's entire Douyin catalog in a sheet: every video, when it went up, what it said and how it performed, to see what they double down on. Tools that read the profile page often return only the first screen, stop after one page, or miss the newest uploads. Two API calls do it: look the profile up once, then page through its video list.

Two calls

1. Account profile with url= set to the profile link (douyin.com/user/... or a v.douyin.com share link). You get id, the account's sec_uid, plus followers, total likes and posts, the number of videos.
2. Account videos with that id. Each page holds about 20 videos, newest first, with ID, link, caption, publish time, likes, comments, shares, saves and hashtags. Pass page.next_cursor back until page.has_more is false.

Cost per account

Videos on the profile	Calls	Cost
100	1 + 5	{{cost:douyin.users.get1+douyin.users.videos.list5}}
400	1 + 20	{{cost:douyin.users.get1+douyin.users.videos.list20}}

Script

import os, requests

API, HEAD = "https://api.okdata.online", {"Authorization": f"Bearer {os.environ['OKDATA_API_KEY']}"}
prof = requests.get(API + "/v1/douyin/users/get", headers=HEAD,
                    params={"url": "https://www.douyin.com/user/MS4wLjABAAAA..."}, timeout=60).json()["data"]["item"]

videos, params = [], {"id": prof["id"]}
while True:
    body = requests.get(API + "/v1/douyin/users/videos/list", headers=HEAD, params=params, timeout=60).json()
    videos += body["data"]["items"]
    if not body["page"]["has_more"]:
        break
    params["cursor"] = body["page"]["next_cursor"]
print(prof["name"], len(videos), "of", prof["posts"])

Gotchas

• The video list needs the sec_uid (MS4wLjABAAAA...), not the short Douyin number shown in the app. The profile call converts a link into it.
• Pinned videos may come first regardless of date; sort by published_at if order matters.
• Private, friends-only and deleted videos are not public, so the list can end below the posts count.
• Play counts are not published for other people's videos; metrics.views is usually null.
