Changes things 2Claude Code: ask
  • verify_frn_couponPAID ($0.25).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.
  • verify_otc_couponPAID ($0.10).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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.

  • get_latest_indexFREE.No findings

    Why it is in this group

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
