What data it sees

Do you need an account

No: the server works without sign-in

Summarize any YouTube video, fetch its transcript, or poll a channel for new uploads — no account, no API key. Payment is the auth: each call is paid per-use in USDC on Base via the x402 protocol, settled only when the call succeeds. A failed call is never charged.

Tools

Tool What it does Price
summarize_youtube_video Claude-generated summary of a video's transcript $0.02
get_youtube_transcript Full transcript text for a video $0.005
list_new_channel_videos New uploads from a channel since a cursor $0.002

How payment works

  1. Call a tool with no payment → you get an x402 402 challenge (price, network, USDC asset, pay-to address).
  2. Sign an EIP-3009 USDC authorization on Base and retry.
  3. The tool runs; payment settles only on success — errors (no captions, bad URL, upstream hiccups) cost nothing.

Works with any x402-capable agent or wallet. No configuration needed — there is nothing to set up.

Notes

  • Summaries are cached: repeat requests for the same video are fast and still just $0.02.
  • Supports every common YouTube URL format (watch, youtu.be, shorts, embeds).
  • Also available as plain HTTP endpoints — see sumvid.app.

summarize_youtube_videoSummarize a YouTube video with Claude and return the summary text, in any of 100+ output languages (`language` param, BCP-47). Pay-per-call via x402 (USDC on Base) — no account or API key. Cheaper than pulling the full transcript into your own context. A bad URL or a video without captions returns an error and is not charged.
get_youtube_transcriptFetch the raw transcript text of a YouTube video (no model run — the cheaper SKU), in any of 100+ languages (`language` param, BCP-47). Pay-per-call via x402 (USDC on Base), no account. A video without captions returns an error and is not charged.
list_new_channel_videosNew videos on a YouTube channel since your last poll — stateless channel monitoring, no accounts or webhooks. Pass a channel URL, @handle, or channel id, plus an optional cursor (`since_video_id` or `since`, an ISO 8601 timezone-aware timestamp) from your last call. Returns new video ids/titles/publish times, newest first, plus `newest_video_id` to use as your next cursor. Pay-per-call via x402 (USDC on Base), no account or API key. An unresolvable channel or a naive `since` timestamp returns an error and is not charged.
