The x402 Register

Research

Independent, measured analyses of the x402 ecosystem, built from our own hourly probes and our own on-chain index. Every figure traces to data we collected, the methodology is public, and rated parties never pay us. New studies are added here.

Census · supply side

The state of x402, measured

Every service in the public catalog, probed hourly and recomputed hourly: quality, spec compliance, price honesty, operator concentration, and on-chain settlement. What the data says, versus what the ecosystem says about itself.

Living page, recomputed hourly. The launch-day edition of 21 July 2026 is preserved at /state-of-x402/2026-07-21.

Study · demand side

The state of x402 demand, measured

Who is actually paying, in three lenses: transactions, dollars, and price-matched settlement. The verifiable agent economy, honestly bounded.
