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

Inspect any media file and get its technical metadata. Container, duration, codecs, DISPLAY dimensions and rotation, frame rate, HDR, audio channels and sample rate, in a normalized summary plus the full raw analysis (JSON, XML, CSV, flat or INI). Provide a source URL or upload the file directly; the result is downloadable for 24 hours. A file that cannot be decoded still answers with the diagnosis of why. Fixed price per probe in USDC over x402; no account or API key. Input up to 100 MB.

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/27602.json for the price and payment options.
Pay. Call GET https://ffpipe.dev/v1/probe. 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.
