Bazaar

Coinbase's documentation describes the x402 Bazaar as a catalogue of payment-gated services discovered by its facilitator, in which a resource is indexed after a settled payment made through that facilitator. The same documentation states when a listing lapses: after a stated period without a settlement, or when the address stops asking for payment.

PayAI's documentation describes its Bazaar as the public catalogue of its own facilitator, filled automatically from the payments that facilitator processes when they carry the seller's discovery declaration. That documentation says cataloguing runs on verification as well as on settlement, and that verification moves no funds.

A count of listings means what its catalogue's rule makes it mean. The entry on a catalogue says what a listing does and does not establish, and the entry on discovery covers how an agent finds a service at all. A Bazaar lists resources, the catalogue's word for what this glossary calls a route.
