sumvid turns any YouTube video into a clean, structured summary. Paste a link, get the gist — powered by Claude, cached globally so popular videos return instantly.
For humans: free tier (5 summaries/day, no credit card), paid tiers for heavier use. Job history, live progress updates, multi-language support.
For AI agents — the interesting part: sumvid exposes pay-per-request endpoints using the x402 protocol. No account. No API key. No signup. Your agent calls the endpoint, gets an HTTP 402 Payment Required with the price, signs a USDC micropayment on Base, retries, and gets the summary.
- 🧾 $0.02 per summary, $0.005 per raw transcript
- 🔐 Payment is the auth — wallet-signed, per-request
- 🛡️ Failed requests are never charged — payment settles only on success, enforced by the middleware, not a refund policy
- 🔎 Discoverable via /.well-known/x402.json and native MCP tools, so agents can find and pay for it autonomously
Why? HTTP 402 sat reserved in the spec since 1996, waiting for a use case. Autonomous agents are it — my bet is that agents (prediction-market bots especially) need fresh info from new videos the moment they drop. Lifetime agent revenue so far: 5.5 cents. The pipes work; the future is loading.
