Douyin Extended boards API

All board entries carry board (the board option name) and rank; most also carry createdAt (publish or creation time).

• boardVideo adds awemeId, description, playCount (plays), likeCount, likeRate (likes per play), followerGain (followers the video brought in), followRate (followers gained per play), score (board heat score), authorNickname, authorAvatar, authorFollowerCount, durationSeconds, coverUrl and url. It has no heat history. Boards lowFanHits, highCompletion, highLikes and followerGrowth use this record.
• boardTopic adds challengeId (hashtag ID; pass it to mode hashtag), word, hotValue, viewCount, videoCount, avgViewCount (average views per video under the topic) and a daily trend as {date, value}.
• boardHotspot adds word, hotValue, rankChange (rank movement since the previous snapshot), videoCount, category (Douyin's tag for the hot spot), sentenceId, cityCode and an hourly trend as {time, hotValue}. Boards challenges and hotTotal use this record too.
• boardWord (boards searchRanking, risingSearches, hotWords) adds word, wordId, hotValue, url and a daily trend.
• boardAccount (board hotAccounts) adds secUid, nickname, followerCount, likedCount, videoCount, followerGain, newLikeCount, followRate and a trend.
• boardEvent (board events) adds eventId, word, category, startDate, endDate, coverUrl.
• boardEventDetail (board eventDetail, one record per ID in eventIds; take the IDs from boardEvent rows) adds eventId, word, category, eventCity, startDate, endDate, publishStartDate, publishEndDate (the window in which videos count), activityDescription, reward, publishCount (videos published for the activity so far), relatedTopics, challenges ({challengeId, name}; pass a challengeId to mode hashtag) and exampleVideos ({awemeId, url, description, createdAt, coverUrl}). An ID the calendar does not know returns nothing.
• Hot word detail (board hotWordDetail, one lookup per ID in wordIds; take the IDs from boardWord rows of board hotWords) returns, for each word, one boardWordDetail record (word, wordId, hotValue, url, daily trend of the word's heat, daily contentTrend, commentTrend, likeTrend, shareTrend, and windows: totals for the last 1, 7, 30 and 60 days) followed by up to 30 boardWordVideo rows (awemeId, url, description, createdAt, durationSeconds, coverUrl, likeCount, commentCount, shareCount, authorNickname, authorAvatar) and up to 9 boardRelatedWord rows (word, wordId, hotValue, url, trend). Rows carry relatedTo and relatedToId (the word they belong to). A word ID is only valid for about a day after its board entry, so use a fresh one: an old or unknown ID returns nothing.
• Creator-center boards (the lists Douyin's creator center shows creators; one list per run, no paging): creatorHotSpots returns boardHotspot (word, hotValue, rankChange, category, queryId, coverUrl, url; hotSpotRanking overall, local or rising); creatorTopics returns boardTopic (word, queryId, playCount, likeCount, commentCount, shareCount, videoCount, publisherCount, coverUrl); creatorMusic returns boardMusic (musicTitle, queryId, hotValue, playCount, likeCount, commentCount, shareCount, videoCount); creatorProps returns boardProp (word, queryId, playCount, videoCount, shootCount, exposureCount, collectCount, likeCount); creatorVideos returns boardVideo (awemeId, url, description, hotValue, playCount, likeCount, commentCount, shareCount, durationSeconds, authorNickname). queryId is the board's own ID, not a Douyin hashtag or sound ID. Topic, sound and prop entries carry no url, hashtag ID or sound ID. A heat value of 0 from Douyin is returned as null.
• DOU+ boards: douplusVideos returns boardVideo for the ranking period (playCount, likeCount, likeRate, followerGain, followRate, completionRate (share watched to the end), score (popularity index), createdAt, authorNickname, authorFollowerCount); douplusTalents returns boardAccount (secUid, url, nickname, douyinId, followerCount, avatarUrl) for one creator category.
• boardMusic (board musicChart) has the sound fields plus hotValue; boardBrand (board brandChart) adds brandId, word, hotValue, heatChange, rankChange, secUid.
