Machines started paying machines. Since August 2026 we archive, every day,
what the rest of the ecosystem doesn't keep about itself — and publish the measurement
once a week, generated straight from the data.
Catalog census — services born and gone in the x402 economy, week by week
Money flow — on-chain payment corridors: who is actually earning, not who is announcing
Protocol pulse — MCP registry growth, paid-web (HTTP 402) adoption by AI crawlers
Agent marketplaces — demand shifts measured across thousands of listed actors
Method. Every number in every edition is computed from our own daily
snapshots — the x402 discovery catalog, the on-chain settlement graph on Base, the MCP
Registry, a census of paid-web adoption, and agent marketplace listings. No number is
typed by hand; editions are generated and published automatically from the archive.
