Yahoo Finance through yfinance: what its own pages say about the data
Open source project on GitHub (ranaroussi). The data is Yahoo's. Community.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

Unofficial. The library's own page says it is not affiliated with, endorsed by or vetted by Yahoo. It reads Yahoo's data, so the terms that govern the data are Yahoo's, not the library's. The library's page was read through a fetch tool that returns the page text. Yahoo's terms of service were not read.
