Get Free API KeyAPI Docs

Track TikTok hashtag trends by polling the hashtag info endpoint daily at $0.005/check. Monitor view count growth, video count changes, and detect trending hashtags before they peak.

Prerequisites

  • Scavio API key
  • Python 3.8+
  • A list of hashtags to monitor
  • Simple storage (CSV or SQLite)

Walkthrough

Step 1: Check hashtag stats

Pull current view and video counts for your hashtag list.

Python
import requests, os, csv
from datetime import date

HEADERS = {'Authorization': f'Bearer {os.environ["SCAVIO_API_KEY"]}',
           'Content-Type': 'application/json'}

hashtags = ['smallbusiness', 'sidehustle', 'techtok', 'booktok']
today = date.today().isoformat()

for tag in hashtags:
    data = requests.post('https://api.scavio.dev/api/v1/tiktok/hashtag',
        headers=HEADERS, json={'hashtag': tag}).json()['data']
    views = data['stats']['view_count']
    videos = data['stats']['video_count']
    print(f'#{tag}: {views:,} views, {videos:,} videos')

Step 2: Store daily snapshots

Append to a CSV for trend analysis over time.

Python
with open('hashtag_trends.csv', 'a', newline='') as f:
    w = csv.writer(f)
    for tag in hashtags:
        data = requests.post('https://api.scavio.dev/api/v1/tiktok/hashtag',
            headers=HEADERS, json={'hashtag': tag}).json()['data']
        w.writerow([today, tag,
            data['stats']['view_count'],
            data['stats']['video_count']])

Python Example

Python
import requests, os, csv, json
from datetime import date

HEADERS = {'Authorization': f'Bearer {os.environ["SCAVIO_API_KEY"]}',
           'Content-Type': 'application/json'}

def track_hashtags(tags, history_file='hashtag_history.json'):
    today = date.today().isoformat()
    try:
        with open(history_file) as f:
            history = json.load(f)
    except FileNotFoundError:
        history = {}
    results = []
    for tag in tags:
        data = requests.post('https://api.scavio.dev/api/v1/tiktok/hashtag',
            headers=HEADERS, json={'hashtag': tag}).json()['data']
        views = data['stats']['view_count']
        prev = history.get(tag, {}).get('views', views)
        growth = ((views - prev) / prev * 100) if prev else 0
        results.append({'tag': tag, 'views': views, 'growth_pct': round(growth, 1)})
        history[tag] = {'views': views, 'date': today}
    with open(history_file, 'w') as f:
        json.dump(history, f)
    return sorted(results, key=lambda x: x['growth_pct'], reverse=True)

trends = track_hashtags(['smallbusiness', 'sidehustle', 'techtok'])
for t in trends:
    print(f"#{t['tag']}: {t['views']:,} views ({t['growth_pct']:+.1f}%)")

JavaScript Example

JavaScript
const H = {'Authorization': `Bearer ${process.env.SCAVIO_API_KEY}`, 'Content-Type': 'application/json'};
const fs = require('fs');
async function trackHashtags(tags) {
  let history = {};
  try { history = JSON.parse(fs.readFileSync('hashtag_history.json')); } catch {}
  for (const tag of tags) {
    const r = await fetch('https://api.scavio.dev/api/v1/tiktok/hashtag', {
      method: 'POST', headers: H, body: JSON.stringify({hashtag: tag})
    }).then(r => r.json());
    const views = r.data.stats.view_count;
    const prev = history[tag]?.views || views;
    const growth = prev ? ((views - prev) / prev * 100).toFixed(1) : '0.0';
    console.log(`#${tag}: ${views.toLocaleString()} views (${growth}%)`);
    history[tag] = {views, date: new Date().toISOString().split('T')[0]};
  }
  fs.writeFileSync('hashtag_history.json', JSON.stringify(history));
}
trackHashtags(['smallbusiness', 'sidehustle', 'techtok']);

Expected Output

JSON
Daily hashtag metrics with growth percentages, enabling trend detection over time. Run as a daily cron for continuous monitoring.
