What this server can do

4 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

get_conventions
FREE. The exact calculation conventions of both engines (listed FRN: SARB §2.2.3 compounded index, 5-bday lookback, Modified Following; OTC: 1-bday lookback, Act/365, half-up 4dp), the verification tolerance, and the index source. Call this first.

verify_frn_coupon(api_key, calc_date, issue_date, margin_pct, lookback_bdays, coupon_frequency, first_coupon_date, expected_coupon_pct)
PAID ($0.25). Independently recompute and verify a listed South African ZARONIA FRN coupon (SARB §2.2.3 compounded-index formula). Returns the coupon to 4dp, full audit workings (observation dates, index values, formula), and a match/mismatch verdict at 0.05bp tolerance when expected_coupon_pct is given. Pass api_key if you have one; otherwise the response explains how to pay via x402. Required: calc_date, issue_date, first_coupon_date, coupon_frequency, margin_pct.
verify_otc_coupon(api_key, margin_pct, settlement_date, expected_coupon_pct)
PAID ($0.10). Independently recompute and verify an OTC money-market ZARONIA coupon (1-bday lookback, Act/365, half-up 4dp). Returns coupon, workings and a verdict at 0.05bp tolerance when expected_coupon_pct is given. Pass api_key if you have one; otherwise the response explains how to pay via x402. Required: settlement_date, margin_pct.
