The available plans
The plans on offer now: what each includes and what it costs. Prices are in minor units — 9900 is $99.00, never a float.
accounts is a capacity limit: you cannot exceed it and be billed for the excess. The monthly allowances can run over where the plan allows it, up to twice the allowance, after which orders are refused — a runaway strategy should not be able to generate an unbounded invoice.
Authorization
apiKey Authorization: Bearer fx_live_<id>_<secret>.
A key is shown once, at creation. We cannot show it again or recover it for you.
Keys carry an environment (live or test) in the key itself, so a test key pasted into a
production config fails immediately instead of at the worst possible moment.
Scopes are per key. A key without accounts:write can read accounts and nothing else.

Nothing changes until the payment is confirmed. By card, the card is confirmed on the checkout page, then `POST /billing/sync` confirms the result; moving between paid plans by card starts the new one today and refunds the unused part of the old. By crypto, the customer pays a one-month invoice to the address shown on the checkout page; an upgrade mid-month is charged the difference, and a downgrade is bought once the current month ends.
This month's usage and what it would cost GET
Counted as it happens rather than derived at the end of the month, so this is the same number the invoice will use. **Over quota, opening is refused and closing is always allowed.** A billing problem must never hold you in a position you cannot exit — an order to close comes back `201` however far over the plan you are, and only opening returns `402 QUOTA_EXCEEDED`.
