Buy credits once.Use them anywhere.

You buy credits and spend them on whatever you want. One wallet covers every app, credits never expire, and there's nothing to cancel — that's the whole model, and packs are the cheapest way to buy them. A plan is the second thing, not the first: it adds what credits can't buy (unlimited brains, more storage, teammates, the API and MCP rails) and refills your wallet every month so you don't have to think about it. The third way is for software: an autonomous agent can call a paid endpoint with no account and no API key, get an HTTP 402 back with machine-readable payment requirements, and settle in USDC on Base.

Yes. One brain is free forever with no credit card: upload sources, build the cited wiki and knowledge graph, ask questions from a bank of 1,000 that never expire, publish a public page, and run unlimited website widgets. Paid plans add the monthly credits that app runs draw from, plus more brains, sources and storage.

Yes, and there is no path by which they could. Credits you bought sit in your wallet until you spend them — no clock, no annual sweep, no forfeiture if you cancel a plan or go quiet for a year. The one pool that does reset is a subscription's monthly allowance, which is granted fresh on renewal and doesn't roll over; spending always draws that expiring allowance first, precisely so a purchased credit is never the one that goes to waste.

An optional setting on your wallet, off unless you turn it on: when your balance drops below a threshold you choose, we buy the pack you picked again and charge the card on file. You set a cap on how many refills can happen in a month, every refill shows up in your ledger as an ordinary pack purchase with a receipt, and you can switch it off at any time. It is not a subscription — nothing recurs on a date, and nothing is charged unless your balance actually runs low.

By what they unlock, not by the credit rate — packs are the cheaper way to buy credits, and a plan never claims otherwise. Free is one brain to try everything. Pro ($12.99/mo, or $9.99/mo billed annually) is the personal tier: unlimited brains, 5,000 questions a month, and API & MCP access. Studio (from $50/mo) removes the “powered by Ounie” badge and unlocks the feed and the AI team. Team (from $300/mo) adds collaborators and shared brains. Enterprise adds SSO, audit logs, EU data residency and custom contracts. Every plan also refills a monthly credit allowance into the same wallet a pack tops up.

Credits are the universal currency across every app, the website widget beyond its included bundle, published sites, and paid brain listings. One wallet per account — there are no per-app plans or balances. Runs are charged server-side and atomically: reserve, then settle or refund. Packs never expire; a subscription's monthly allowance is granted fresh on renewal and is always spent first.

Asking your own brains — that's your plan's question quota (5,000/mo on Pro, 15,000 on Studio, 30,000 on Team, and a non-expiring 1,000-question bank on Free). So is your included widget-question bundle, editing your wiki, restyling, reverting and publishing a site, and swiping the feed. A thin result — an empty dataset, a failed render, or an honest “not in your brain” — costs nothing on either rail.

Buy a pack, or turn on auto-refill so it happens without you. No plan change is required and there's nothing to upgrade — a pack works identically on Free and on Team. Unused monthly allowance doesn't roll over, but everything you bought stays put.

Paid actions quote an “up to” price in the 402 response: a heavy job settles higher than a light one, but never above the quote, so an agent can encode the ceiling before it spends. Empty or failed results settle zero. Paid actions and paid brains are also indexed in the x402 Bazaar so an agent can discover them without reading our docs.

No. There's no setup fee and no onboarding tier — you create a brain, point an agent at the gateway or open an app dashboard, and start. If you'd rather have it built for you, that's a separate service quoted per project rather than a line on this page.

Yes. Paid plans are month-to-month and you can cancel from your billing settings — you keep access through the end of the period, and your brains and sources stay intact when you return to the free plan.
