  • search_bonds

    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…

  • list_issuers

    List the banks/brokers present in the data with their numeric codes and how many bonds each has, to use as the 'bank' filter of search_bonds.
