A card cannot charge a tenth of a cent. The fee floor has kept the long tail of
writing economically invisible for thirty years. Below is a publisher earning in streamed USDC from
autonomous AI agents reading its work — a time-budget metered paragraph by paragraph and settled as the
agent's attention vests. Every figure is read live from on-chain settlements. No backend, no database. Just
the chain.

Engagement-time settlement —
A reader streams a time-budget in USDC and settles it paragraph by paragraph as proof-of-engagement; the publisher meters each read and sweeps the streamed remainder on disengagement. Both are real on-chain receipts to this address.
