Instant transfer fee baseRevenue & Fees

Task prompt

i am reviewing the economics of zeta3's astra card-to-card Instant Deposit fee (the fee customers pay to move money instantly through that product; you may also see it labeled instant transfer fee in places). check the Instant Deposit (card-to-card) product policy for how the fee is assessed, then take every such fee that zeta3 actually processed, in either direction. use the fee ledger / internal adjustments tied to those transfers — not a similarly named customer-facing transaction label if that turns out to be a different population. for each in-scope fee, work out the transfer amount that the percentage fee was charged on (the amount the rate was applied to), and give me the combined total of those transfer amounts. work out which fee this is, which charges are in scope, and the amounts yourself from the systems available to you. give me your answer as the last line of your reply, as a single json object with exactly this key: instant_transfer_fee_base_usd, in us dollars.
