  -H "Authorization: Bearer ${KOLENS_API_KEY}"

# All KOLs
curl "${KOLENS_API_URL}/api/kols?keyword=[KEYWORD]&per_page=30" \
  -H "Authorization: Bearer ${KOLENS_API_KEY}"

Response:

{
  "total": 6,
  "page": 1,
  "per_page": 30,
  "kols": [
    {

Workflow Example

# 1. Submit job
curl -s -X POST "${KOLENS_API_URL}/api/scrape" \
  -H "Authorization: Bearer ${KOLENS_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{"keyword":"camping","max_videos":30,"fetch_contacts":true}' > /tmp/job.json

JOB_ID=$(cat /tmp/job.json | jq -r '.job_id')
echo "Job ID: ${JOB_ID}"

# 2. Poll until completed (every 90s)
for i in 1 2 3 4 5 6 7 8 9 10; do
  STATUS=$(curl -s "${KOLENS_API_URL}/api/jobs/${JOB_ID}" \
    -H "Authorization: Bearer ${KOLENS_API_KEY}" | jq -r '.status')
  echo "Status: ${STATUS}"
  if [ "${STATUS}" = "completed" ]; then
    echo "Job completed!"
    break
  fi
  sleep 90
done

# 3. Get KOLs with email
curl -s "${KOLENS_API_URL}/api/kols?keyword=camping&require_email=true" \
  -H "Authorization: Bearer ${KOLENS_API_KEY}"

Troubleshooting

• Task stuck in "running": The scraping typically takes 2-3 minutes. Continue polling.
• "Invalid or inactive API key": Your API key may have expired. Contact the KOLens admin for a new one.
• Empty results: Try different/ broader keywords, or check if TikTok has content for that keyword.
• Rate limiting: If you get rate limited, wait before making more requests.
