}Daily 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. Price: $0.01 USDC per successful call.

}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. Price: $0.01 USDC per successful call.
