}⚪verify_frn_coupon(calc_date, issue_date, first_coupon_date, coupon_frequency, margin_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.
