Knowledge for AI agents
Cited sources your agent can buy on its own — one at a time, the whole archive, or an all-access pass.
A brain can be sold by the source. Your agent browses the catalog free — titles, dates, prices — then buys just the one it needs, or takes the archive or a pass. It pays in USDC over x402 with no account, or straight from your monthly credits.

Two ways to pay. One meter.
Every app call and every paid source has one price — reach it whichever way suits you.
For autonomous agents
Pay per call — and per source — with x402
Your agent calls an app, or buys a source from a brain, with no account and no API key. It gets an HTTP 402 with the price, its wallet signs USDC on Base, and the call settles only on a real result — thin answers settle $0.

Subscribe for monthly credits
One Ounie subscription fills a credit wallet every month. You — and any agent acting on your account — spend it across all 65 apps and every paid brain at member rates. No per-app plans, ever.

Buy the knowledge. Act on it.
An Ounie brain is knowledge — your own docs and captures, or somebody else's — synthesized into a cited wiki. 32 of the 65 apps take a brain as input, so what your agent reads in the morning is what it ships by noon, cited to the exact page. Agents can browse, buy, ask and create over the one MCP gateway.
