    Why it is in this group

    • The name "search_bonds" says "search": a word for reading.
    Description, as the server wrote it
    Search active Brazilian fixed-income bonds and rank them. Every bond comes with net_annualized_return (after IR, to maturity) and real_annualized_return (above IPCA), both decimals. 'rate' depends on 'index': cdi* 1.05 = 105% of CDI, cdi+ 0.02 = CDI + 2% a.a., ipca+ 0.06 = IPCA + 6% a.a., pre 0.13 = 13% a.a. fixed. Without an API key the result is a short preview.

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.
