Independent, reproducible measurements — what machine-payable services actually do when you try to pay them. Every number is drawn from public, Bitcoin-anchored sweeps and can be recomputed.
It’s not one rail — it’s a dozen.
Extending the measurement to a second standard (MPP, alongside x402) shows the economy isn’t a two-horse race: verified settlement spreads across roughly eight chains. A look at cross-rail sprawl, MPP’s early-but-real adoption, and why a measurer that sees only one rail isn’t neutral.
What x402 services actually do when you try to pay them.
Knocking on every listed x402 service several times a day and watching the money on-chain: how many are actually payable, whether prices tell the truth, and what the on-chain receipts reveal about real demand versus wash — measured, not asserted.
