What are verifyFp and s_v_web_id on Douyin? (2026)
As of 2026, they are one value under two names: s_v_web_id is a cookie on Douyin's web pages, and verifyFp and fp are the request parameters that carry it. We found no public explanation from Douyin; this is how open-source projects use it. With a data API you handle none of them: a video's details are $0.0020. DataXAPI reads Douyin with 36 endpoints, from $0.0020 a call; a failed call is not charged.

Why you run into them
You see them when your own program reads a Douyin video's details. MediaCrawler's code notes that on that address they go with uifid, and that the request gets 403 with a body like Blocked by ArgusSecurityPlugin Uifid Not Found when these are missing. f2 uses one routine for verifyFp and s_v_web_id. How the value is obtained is not something we cover.
If you would rather not deal with them
Each job is one call. A video from its link: douyin.videos.get, $0.0020. Its comments: douyin.videos.comments.list, $0.0020 a page. An account's videos: douyin.users.videos.list, $0.0020 a page. None takes these values, a signature or a cookie from you. One page of videos from 100 accounts comes to $0.20, and a failed call is not charged.
Endpoints
Each with its price; every page has the parameters, the fields and a recorded response.
