"""# Financial Depository Fetchers.
|
|
|
|
Python library for programmating downloads of asset position information from
|
|
personal depository accounts.
|
|
|
|
This library is a core part of my personal financial applications, as it allows
|
|
me to monitor my investments on financial markets and web3 investments.
|
|
|
|
A lot can be said (mostly negative) about web3, but at least they are serious
|
|
about API access, which the modern banking system is not great at providing.
|
|
Even in The European Union, where GDPR is law and OpenBanking is a requirement,
|
|
it is hugely difficult for people to access and control their own personal
|
|
financial information.
|
|
|
|
This is a library; if you want a simple program for downloading the information
|
|
exposed by one of the supported services, try [my personal-data-fetchers
|
|
program](https://gitfub.space/Jmaa/personal-data-fetchers).
