Rubicon prices content by the word. Writers set a per-word rate in USDC, and agents pay only for the words that are actually streamed and read—not for the full article upfront.

For quick answers, the gateway streams and settles one word at a time. Each delivered word triggers a tiny USDC payment, so agents can stop the moment they have enough evidence.

For longer reads, the gateway bundles a contiguous run of words into a single chunk released by one payment. That cuts round-trips and speeds delivery while still metering exactly what was read.

Yes. You earn for exactly the words that were read—whether the agent stops after a definition or continues through multiple sections.

Short reads stream and pay word by word. At scale, Rubicon batches consecutive words into bundled payments so micropayments stay practical without losing per-word attribution.

A single word can cost a fraction of a cent. Card rails would lose that to fees, so Rubicon settles every word as a USDC nanopayment—a transfer small enough to move per word, instantly, without a fee swallowing the payment. Writers set the per-word price, and each word settles in USDC with no card fees eating sub-cent amounts.

Rubicon runs on Circle's stablecoin infrastructure and Arc, Circle's USDC-native chain where stablecoins are the gas. That makes paying for one word, then another, thousands of times over, economically real.
