Take a cancellation back
While the paid period still runs, a plan set to cancel at its end carries on instead: a card plan renews again, a crypto plan can be extended again.

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 a label (live or test) in the key itself, so each configuration is easy to tell
apart. Both reach real brokers: test with a broker demo account.
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.
The available plans GET
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.
