Measurement

seller

The seller is the address that received the payment. In x402 that is the payTo recipient of the USDC transfer. In an MPP session it is the payee on the Settled event. One seller can host many Bazaar resources. Use-case categories are attached to those resources and then reported on the seller's volume.

Explanation

Seller rankings use the selected window. Organic status is a property of the seller in that window, not a permanent label. A seller that is a facilitator settlement wallet fails the organic screen even if it also sells a service. The top facilitator for a seller is recorded so fee routes are visible.

The resource catalog is not a complete list of sellers. Settlement can happen before the hourly Bazaar crawl links a URL, and some payees never publish catalog metadata. Those payees remain in the volume total and show up as unclassified in the use-case rollup until a resource matches.
