}Preview a 100-coin order (step 1 of 2)
Computes the summary the user must confirm and, when the order is
currently possible, mints a confirm_token for POST /orders.
Charges nothing. Requires the write scope; counts against the
read window only.
When can_place is false the reason says why and no token is
issued. With MECHANISM_UNSUPPORTED (a v2_share topic) the summary
is partial: only topic_title, option_label, stake_coins, the
balances, price_now, close_time and mechanism are meaningful.

}Authorizations
Personal API key issued per SeeSaw user account:
Authorization: Bearer sspat_…. Manage keys on the app API
(/v1/users/me/api-keys). Revocation propagates within ~60 seconds
(validation cache window).
The key's scopes decide what it may do: every key has read; a key
created with ["read","write"] may also use the six write operations
(marked x-required-scope: write in this document). Scopes are fixed at
creation — to gain write access, create a new key. A read-only key
calling a write operation gets 403 FORBIDDEN_SCOPE.
Path Parameters
Topic UUID.
Body
The option to stake on, from the topic's options.
Response
The preview (check can_place before confirming)
What the user confirms before POST /orders. payout_if_correct_rubies
equals the order's units — the rubies received if the option wins; the
100-coin stake is not returned.
