How this service works
Pay-per-call structured web data. Failed or empty runs are not charged.
Output
Returns a JSON object with a count of retrieved items and an array of comment records. Each record includes the comment ID, text body, author display name, comment permalink URL, author avatar image URL, author channel ID, author channel URL, and a boolean indicating whether the author is verified. Failed or empty scrape runs are not billed.
Example use cases
Sentiment analysis on viral video
“Pull the top 500 comments from https://www.youtube.com/watch?v=dQw4w9WgXcQ sorted by featured ranking, including replies, so I can run sentiment analysis on them.”
Brand monitoring on product review
“Collect up to 200 of the newest comments posted after 2024-01-01 on https://www.youtube.com/watch?v=abc123XYZ — I want to see what people are saying about the product in this review video.”
Creator community research
“Fetch the 100 most recent comments, with replies, from each of these three YouTube videos: https://youtu.be/vid1, https://youtu.be/vid2, https://youtu.be/vid3 — cap the total at 250 items across all three.”

Endpoint
POSThttps://x402.186-241-26-229.sslip.io/v1/youtube-comments?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable comment data from specific YouTube videos without building or maintaining your own scraper. It is especially well-suited for agent workflows that require pay-per-use pricing (no subscription), tolerance for failed runs at no cost, and support for replies alongside top-level comments. Prefer it over generic web scrapers when you need YouTube-specific output fields like channel IDs and verified status.
Side effects
- Video is private or age-restricted — returns empty result, no charge
- Invalid or malformed YouTube URL — request rejected
- Video has comments disabled — returns empty result, no charge
- Rate limiting or YouTube anti-bot measures — may return partial or empty result
- Network timeout on large comment sets — partial result possible
