ChileDataAPI

The ChileDataAPI package provides a unified interface to access open data from the FINDIC API and the REST Countries API, with a focus on Chile. It allows users to easily retrieve up-to-date time series data on financial indicators such as the UF, UTM, Dollar, Euro, Yen, Copper price per pound, Bitcoin, and the IPSA index, as well as international metadata on countries via standardized API calls.

All API-based functions return data as tidy tibble objects, making them ready for immediate use in data pipelines. The financial indicator functions, such as get_chile_dollar(), get_chile_uf(), and get_chile_bitcoin(), provide real-time series of daily or monthly values, with each row representing a timestamped observation. This makes ChileDataAPI a valuable tool for working with economic time series data in a reproducible manner.
