Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

accrued_interestAccrued interestread-only
Exact simple accrued interest (notional * rate * day-count fraction) between two dates. Dates are ISO YYYY-MM-DD; rate is the annual rate as a decimal (0.05 = 5%). Deterministic.
add_business_daysAdd business daysread-only
Move a signed number of business days under a holiday calendar (settlement math: T+2 is count 2). Zero returns the date unchanged. Deterministic.
adjust_dateAdjust to a business dayread-only
Adjust a date to a business day under an ISDA convention and holiday calendar. Business days pass through unchanged. modified-following falls back to preceding rather than leave the month (the bond-market default). Deterministic.
day_count_fractionDay-count fractionread-only
Exact day-count fraction between two dates under a market convention. Dates are ISO YYYY-MM-DD. For ACT/ACT ICMA also pass frequency (coupons per year) and, for stub periods, the reference period boundaries. Deterministic; do not estimate this with a model.
generate_scheduleGenerate a payment scheduleread-only
Generate coupon/payment accrual periods between an effective and a termination date: monthly to annual frequency, backward or forward roll, short or long stub, optional end-of-month rule, business-day adjustment per calendar. Returns each period's unadjusted and adjusted start and end. This is where hand-rolled date code goes wrong; do not approximate it.
is_business_dayBusiness-day checkread-only
Whether a date is a business day under a holiday calendar, with the reason when it is not (weekend or holiday). Calendars are rules in code (no stale data feed). Deterministic; do not let a model guess market holidays.
list_calendarsList calendarsread-only
List the supported holiday calendars with a one-line description of each.
list_conventionsList conventionsread-only
List the supported day-count conventions.
