How this service works
x402vid — endpoint discovery for YouTube intelligence: pay-per-call via x402 on Base. Muse Spark 1.3 video intelligence, 26 tools (20 paid +6 free) from $0.01. Free before you pay: GET /api/v1/catalog (every tool + price) → GET /api/v1/quote (freeze price) → video_preview. No subscriptions.
Output
Returns a structured comments report object containing AI-generated intelligence about the sampled comments (themes, sentiment, key reactions, notable quotes, etc.), the video ID, and the number of comments actually sampled.
Example use cases
Brand sentiment on product launch video
“I just published a product launch video on YouTube — here's the link: https://youtu.be/abc123xyz — can you analyze the comments and tell me how people are reacting? Sample 100 comments.”
Competitor video audience analysis
“Can you pull a comment analysis on this competitor's tutorial video at https://www.youtube.com/watch?v=XYZ789 and summarize what the audience is saying about it?”
Creator feedback loop research
“I'm a YouTuber trying to understand what my viewers think of my latest video — analyze the comments here: https://youtu.be/myVideoId — use the default sample size.”

Endpoint
POSThttps://x402vid.com/tools/analyze_comments?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured AI intelligence specifically about a YouTube video's comment section — audience sentiment, recurring themes, viewer reactions — rather than the video content itself. It is pay-per-call with no subscription overhead, making it ideal for on-demand, agent-driven workflows. Prefer this over generic scraping tools when you want an AI-synthesized report rather than raw comment data.
Side effects
- Invalid or private YouTube URL returns an error — video must be publicly accessible
- Comment section disabled or empty results in no data to analyze
- max_comments exceeding 100 is clamped or rejected
- Payment failure (insufficient USDC balance or x402 auth error) blocks the call
- Rate limiting if too many calls are made in quick succession
