How to find viral TikToks with Jev

# 1. Search a keyword. Keep creators with 5,000+ followers.
curl -s https://treg.to/call/treg.tiktok.search.videos \
  -H "X-Treg-Token: YOUR_TREG_TOKEN" \
  -H "X-Treg-Route-Max-Cost: 0.02" \
  -H "Content-Type: application/json" \
  -d '{"q": "easy recipes", "limit": 30}' > search.json

jq '[.output.videos[].aweme_info.author | select(.follower_count >= 5000)
     | {handle: .unique_id, sec_uid}] | unique_by(.handle)' search.json > creators.json

# 2. Each creator's recent videos. One call per creator.
curl -s https://treg.to/call/treg.tiktok.user.videos \
  -H "X-Treg-Token: YOUR_TREG_TOKEN" \
  -H "X-Treg-Route-Max-Cost: 0.02" \
  -H "Content-Type: application/json" \
  -d '{"sec_uid": "SEC_UID", "limit": 30}' > HANDLE.json

jq --arg c HANDLE '[.output.videos[] | {creator: $c, plays: .stats.plays,
     caption: .description, hashtags, sound: .music.title, url}]' HANDLE.json > videos-HANDLE.json

# 3. One list
jq -s add videos-*.json > videos.json

# videos.json: [{"creator": "...", "plays": 824400, "caption": "...", ...}, ...]  (from step 2)
