Tools (2)
search_bonds582 tokSearch 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.
list_issuers60 tokList 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.
