obrotomierz open data
ChatGPT pluginSavings bonds and bank data
Read-only access to three open datasets published by obrotomierz.pl, a Polish website about safe savings. No sign-in.
Polish retail treasury savings bonds (OTS, ROR, DOR, TOS, COI, EDO, ROS, ROD): the current offer, and any series since 1999 by its code, with the margin, early redemption fee and the interest rate in every period that has started.
Retail government bonds in 195 countries (UN members, the Holy See and Palestine) and Hong Kong: whether a country sells government bonds to individuals at issue and how they pay (inflation plus a fixed margin, market real rate, fixed, floating, step-up or prize), with an official source for each country.
Banks in the 27 EU countries that pay a cash bonus for opening a personal current account, read one by one from bank websites, with the amount, deadline and source page.
Every answer names its source, the CC BY 4.0 license and the dataset DOI in Zenodo. Intended for people comparing safe savings options and for researchers and journalists. Limitations: the data is information, not financial advice; bank terms change often, so the binding terms are always on the bank or issuer page. The plugin cannot buy bonds, open accounts or access any user account.
