Reference Account

Account

Returns the signed-in account's balance and deposit address, and its spend by day and model.

GEThttps://api.runmoth.si/v1/account

Both account endpoints take a wallet session from sign-in, not a key. A key reads the same balance through usage.

balance_usd already leaves out the holds still open, and deposit_address is the account's own USDG address on Robinhood Chain, or null while deposits aren't open.

Spend by day and model

GET /account/usage?days=30 lists the account's spend for the last 1 to 90 days, 30 by default, as one row per day and model, newest day first.
