A metered read on x402 Bazaar: observed USDC money flow, daily movement, new entrants, category pressure, and payTo change alerts. Every output names its table, its real observation window, and its blind spots.
Agent catalogCoverage & statusDaily state of the x402 agent economy: observed USDC inflow, seller ranking, category demand, growth, and coverage. Reports its real observation window; concentration adjustment applied only when scan coverage supports it. A FREE register-wide change digest covering the same domain is market_digest on the x402-observatory gateway; buy this for the derived figures, not for what merely changed.
Which x402 sellers actually earn, ranked by USDC read off Base — not by their own claims.
Which x402 services are growing right now, by observed inflow across comparable windows.
x402 services first listed since a given date, with first archive observation and early-traction evidence from observed inflow. Entrants MCPFax can attribute — a declared payTo, an observed title, or observed inflow — rank first, and each row says which it carries. A window identifying nobody is refused 422 and charges nothing. Requests before the archive's first date are partially covered.
Where agents are spending and almost nobody is selling — demand against classified supply.
Sudden inflow spikes and first-seen large payers, before they show up in a ranking.
Pay per call — these are the only prices on this page, and every one of them is live. Successful calls settle exact native USDC on Base. Unpaid calls return a machine-readable 402 challenge. The same six products are exposed as paid MCP tools at POST /mcp.
Inflow means incoming Base USDC Transfers to a declared payTo. It is not balance, audited revenue, or guaranteed x402-only flow.
A seller below the observation floor, or with no payer rows at all, comes back unrated. Absence of data is never published as a risk verdict about a host, a wallet, or a payer.
Scan coverage, the real first observation date, and the actual number of calendar days held ship in every response. The wash adjustment is suppressed, and never ranked on, until scan coverage supports it.
