How the list is made
From the agent census: every x402 endpoint of an ERC-8004 agent on Robinhood Chain that answered with payment terms when the census read it: its URL, the price it asked and its payTo. Agents sharing one endpoint are one row.
From payments settled here: a payment settled through Toll’s facilitator whose payload carries the x402 bazaar extension adds the seller’s own description of the resource. Its discovery info is checked against its schema first; a schema over 64 KB or one that points outside itself is refused and nothing is fetched.
Verified means the payTo is the agent wallet its ERC-8004 identity registered (ERC-8478); it does not say the seller delivers, or that it is who its name suggests. Names and descriptions are the sellers’ own words. Settled through Toll counts payments to that resource settled by this facilitator. More on the label: what payTo verified means.
One row per operator: agents on one platform or one site are one operator (the x402 Register’s rule), so one operator’s thousands of agents do not fill the list. Its best row is shown (verified first, then payments settled, then the newest), with how many more it has.
Endpoints
The x402 v2 discovery API, open to every origin, no key:
GET https://x402.t0ll.xyz/discovery/resources?type=http&limit=20&offset=0 filters: payTo, scheme, network, extensions=bazaar, operator
GET https://x402.t0ll.xyz/discovery/search?query=weather&limit=10
Each item is the spec’s resource (resource, type, x402Version, accepts, lastUpdated) plus verified, settledViaToll, operator and price. Agents over MCP: the find_paid_api tool at https://t0ll.xyz/mcp answers the same list in text.
