## How paying works

- Everything is paid from a prepaid balance. Minimum top-up $10.
- An agent calls POST /v1/account/topup and hands the returned checkout_url to a person. That is the one step that needs a human.
- Optional auto top-up refills the balance from the saved card ($10 by default) when a send would not fit.
- Usage charges in a month never exceed a budget ($20 by default). An agent can lower it; only a person can raise it.
- Every send response reports what it cost. dry_run shows the cost first; max_cost_usd refuses a send that would cost more.

0% on sending. The $5 sending-month fee is the only place we make money; every email beyond the included 10,000 is billed at published cost.
