Behind Viral Short Videos: How to Predict TikTok Trends Using API

Introduction

What kind of short videos go viral? Is it appearance? Humor? Music? Or just pure luck?

In reality, TikTok’s popularity follows patterns. By systematically tracking multiple data dimensions such as "challenges", "music", "hashtags", and "trending keywords", it is possible to detect trends before they fully explode.

This article introduces how to use LuckData's TikTok trend-related API to build a “Short Video Trend Radar” that helps content creators and brands:

• Quickly identify rising trend directions

• Predict the peak timing of challenges, topics, and BGM

• Optimize video publishing time and creative strategy

1. How Are Trends Formed? The Logic Behind Going Viral on TikTok

A viral trend usually emerges through the amplification of multiple data points:

• A hashtag or challenge appears

• Influential creators participate and contribute videos

• Video views and likes surge rapidly

• More users imitate and create similar content

• The content makes it to TikTok’s recommendation or trending pages, triggering wider attention and discussions

If you can identify and participate during the early stage of a trend, your content has a much higher chance of being boosted by the algorithm.

2. What Can LuckData’s Trend API Do?

LuckData provides a suite of TikTok trend-tracking APIs that return valuable insight into what’s currently gaining traction. Here are some key endpoints:

✅ Challenge Ranking

GET /api/tiktok-api/get_challenge_ranking?region=US&sort=rise

Returns information such as:

• Challenge name (e.g., #outfitchange)

• Usage count (number of users joining the challenge)

• Total play count

• Growth trend over the past 24 hours

This helps identify which challenges are starting to gain traction.

✅ Hot Music Ranking

GET /api/tiktok-api/get_music_hot?region=US&time_range=weekly

Returns weekly trending background music with fields including:

• Music name

• Number of videos using the track

• BGM ID (can be used to fetch related videos)

This data is crucial for selecting trendy and high-engagement audio for your videos.

✅ Hashtag Heat Tracking

GET /api/tiktok-api/search_challenge?keyword=trend&page=1

Search for trending hashtags using keywords, and filter based on:

• Frequency of use

• Recent growth rate

• Content category (e.g., comedy, beauty, travel)

This is ideal for discovering niche topics or emerging trends.

3. Hands-On: Using Python to Track Rising Challenge Trends

Here's a basic example of how to fetch challenges that have quickly gained popularity over the past 24 hours:

import requests
headers = {'X-Luckdata-Api-Key': 'your_luckdata_key'}
res = requests.get(
'https://luckdata.io/api/tiktok-api/get_challenge_ranking?region=US&sort=rise',
headers=headers
)
for item in res.json().get("data", []):
print(f"Challenge: {item['name']}, Used: {item['used_count']}, Views: {item['play_count']}")

You can use this data to:

• Select rising challenges to participate in

• Determine whether a challenge is cooling down

• Help brands decide if it's the right time to engage or launch a campaign

4. How to Build a Trend Prediction Dashboard

To build an effective TikTok trend prediction dashboard, consider integrating the following modules:

You can use Tableau, PowerBI, Plotly, or Dash to visualize the data and update in real-time using LuckData’s API.
