    loan_createRecord a loan or lease and return its id, level payment and effective annual rate. principal_minor, fees and balloon are whole MINOR units; rate_bps is the nominal annual rate in basis points. Free: 3 agreements.
    loan_scheduleBuild one loan's schedule: opening balance, payment, interest, principal and closing per period, with total interest. The last period absorbs rounding, landing exactly on the balloon or zero. loans_report totals it.
    loan_repay_earlyWork out what settling or overpaying costs as of a period: the outstanding balance, the penalty if one is given, the recalculated remaining schedule and the interest saved, stated gross and net of the penalty. Pro.
    loan_journalReturn the double entry for one payment period or month: debit interest expense and loan liability, credit cash, in the cash book's account names, with an expense_add-ready payload. Give period or month, not both. Pro.
    loan_listList the register with terms, level payment, effective annual rate and, at as_of, periods paid, balance outstanding, interest to date and the next payment, totalled per currency. Free; loans_report is the Pro roll-up.
    loan_deleteRemove one loan or lease from the register and give its free-tier slot back. Refused, with the entry named, if a journal has already been taken from it. Free.
    loans_reportThe debt at as_of: per loan what is outstanding, whether it is settled, the next payment, and the interest and principal charged in a year, then totals per currency. Contractual balance, not cash paid. Pro.
    license_statusReport this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
    license_activateTurn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
