Mirrored from Coinbase's public x402 Bazaar. The description is the provider's own text and has not been reviewed here; the payment requirements are copied as published.

What it does

YouTube video metadata in one call: title, channel name and id, duration, upload date, view and like counts, description, thumbnail URL, the chapter list with start and end times, and the language plus kind (manual or auto) of every available caption track. Never downloads media. Use it to check a video's length or caption availability before paying for a transcript, or to enrich a bare video link with real facts.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/26922.json for the price and payment options.
Pay. Call GET https://video.cyberwarex.com/meta. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
