title: 'yfhist: Yahoo Finance ''history'' API'
version: 0.1.4
doi: 10.32614/CRAN.package.yfhist
abstract: Simple and efficient access to Yahoo Finance's 'history' API <https://finance.yahoo.com/>
  for querying and retrieving financial data. The 'yfhist' package abstracts the complexities
  of interacting with Yahoo Finance APIs, such as session management, crumb and cookie
  handling, query construction, date validation, and interval management. This abstraction
  allows users to focus on retrieving data rather than managing API details. Use cases
  include retrieving historical data across a range of security types such as equities
  and ETFs, indices, and other tickers. The package supports flexible query capabilities,
  including customizable date ranges, multiple time intervals, and automatic data
  validation. It manages interval-specific limitations automatically, such as lookback
  periods for intraday data and maximum date ranges for minute-level intervals. The
  implementation uses standard HTTP libraries to handle API interactions efficiently
  and is available in both R and 'Python' for accessibility to a broad audience.
