Pay in RUSD on Robinhood Chain or USDC on Base.
The rails
One gateway. Two payment rails.
Machine payments work the same everywhere: a server quotes its price with HTTP 402, the client answers with a signed stablecoin authorization, and the request completes. No accounts, no API keys, no invoices.
HTTP 402 · Robinhood Chain
RUSD on Permit2: witness transfer pinned to the merchant, relayer broadcasts, gas sponsored on Robinhood Chain. USDC on Base where listed.
