Pricing

Credits

One credit is one penny. A credit is charged when an operation costs this instance money: a model call, or a third party billed per request. Everything else is 0.

No subscription, no minimum, no expiry. Top up any amount at your account.

An agent can skip the account: call without a token and a priced tool answers 402 with an x402 challenge, payable in USDC on Base. See the API.

The agent is free

Chatting, your inbox, your files: no credits. You pay for the tools a run reaches for, one line each on your receipt. Most answers reach for none.

Your mailbox

Receiving costs nothing, however much arrives. Reading it costs nothing — the address works in Thunderbird, Mail.app or your phone over IMAP, and you can reply from there over SMTP, with an access token as the password.

Mail addressed outside the instance is 4p, capped at 50 a day. It is the one price here that is not a cost: sending costs us nothing, but what a loop spends is this domain's reputation, and no balance repairs that. The Email tool is a different thing on a different domain, with a cap of its own — see the table.

Local mail — one account on this instance to another — is free, and so is anything the agent answers.

You pay for a fetch

A price is what it costs to go and get something. If this instance already has the answer — a forecast someone asked for in the last half hour, a map tile fetched once — you are not charged. The more people use an instance, the less each of them pays.

Prices

Most apps are free. Paid ones show their price before you run them; the author keeps 90%.

Self-hosting

One Go binary, source here. Every price above comes from one file in it, so an instance you run charges what you set — including nothing. Callers pay you.
