Example use cases
Audience sentiment deep-dive
“Grab the top 8 comment threads and up to 20 replies each from this YouTube video — https://www.youtube.com/watch?v=abc123xyz — I want to understand what the audience is actually debating in the replies.”
Brand monitoring on product review video
“Pull the top 10 comment threads with 15 replies each from this YouTube review video at https://www.youtube.com/watch?v=productReview99 so I can see what customers are saying about the product in the discussions.”
Content research for follow-up video
“Mine the reply threads from this YouTube video https://www.youtube.com/watch?v=tutorial456 — get the top 5 threads with 10 replies each — I need to find the most common questions people are asking so I can address them in my next video.”
Technical details
Endpoint
POSThttps://x402vid.com/tools/comment_replies?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, nested comment thread data — including replies to top comments — from a specific YouTube video. It is ideal for audience research, sentiment analysis on comment discussions, brand monitoring, or content planning where understanding reply-level discourse matters. Prefer this over general comment scrapers when you want pay-per-call pricing with no subscription and need the reply layer, not just top-level comments.
Side effects
