💰 Pricing

Pay-per-event pricing:

• $0.001 per comment scraped (including replies)
• $0.01 per post processed

Example costs:

Scenario	Cost
50 comments from 2 posts	$0.07
100 comments from 5 posts	$0.15
500 comments from 10 posts	$0.60

Use the maxDatasetItems parameter to set a hard cap on items saved and control costs.

⚡ Performance Tips

• Use 1–3 posts per run for optimal speed
• Set commentsPerRequest to 5–10 for a good balance between speed and rate limiting
• Keep cookies fresh — update them weekly for reliable scraping
• "Most Relevant" sort supports full pagination; "Most Recent" uses offset-based pagination

🛡️ Built-in Protection

• Smart rate limiting with configurable delays between requests
• Automatic retries for transient failures (configurable via maxRetries)
• Dataset item cap prevents runaway costs (maxDatasetItems)
• Graceful error handling — one failed post won't stop the entire run

🔧 Troubleshooting

Problem	Solution
"No comments found"	Check that the post has public comments and your cookies are valid
"Cookie not valid" / auth errors	LinkedIn cookies have expired — export fresh ones
Fewer comments than expected	Some comments may be filtered (author comments, replies) or the post may have fewer than requested
Run stops early	Check if maxDatasetItems limit was reached

📞 Need Help?

1. Make sure your LinkedIn cookies are fresh (less than a week old)
2. Verify post URLs are correct LinkedIn post links
3. Try with a small maxCommentsPerPost first to test your setup

Happy scraping! 🎉
