Introduction

The BrazilDataAPI package provides a unified interface to access open data from the BrasilAPI and the REST Countries API, with a focus on Brazil. It allows users to easily retrieve up-to-date information on postal codes, banks, economic indicators, holidays, company registrations, and international country-level data relevant to Brazil.

In addition to API-access functions, the package includes a collection of curated datasets related to Brazil, covering diverse domains such as demographics (male and female population by state and year), river levels in Manaus, environmental emission factors in São Paulo, Brazilian film festivals, and historical yellow fever outbreaks.

BrazilDataAPI is designed to support research, teaching, and data analysis focused on Brazil by integrating public RESTful APIs with high-quality, domain-specific datasets into a single, easy-to-use R package.

Functions for BrazilDataAPI

The BrazilDataAPI package provides several core functions to access real-time and structured information about Brazil from public APIs such as BrasilAPI and REST Countries. Below is a list of the main functions included in the package:

get_brazil_banks(): Get List of Banks in Brazil
get_brazil_cep(): Get Address Information by Brazilian CEP (Postal Code) Example: get_brazil_cep(“89010025”)
get_brazil_cnpj(): Get Company Information by CNPJ (Brazil) Example: get_brazil_cnpj(“19131243000197”)
get_brazil_municipalities(): Get Municipalities of a Brazilian State from IBGE Example: get_brazil_municipalities(“SP”)
get_brazil_rate_name(): Get Specific Brazilian Economic Rate by Name Example: get_brazil_rate_name(“CDI”)
get_brazil_rates(): Get Official Interest Rates and Indexes from Brazil
get_brazil_vehicle_brands(): Get Vehicle Brands from BrasilAPI (FIPE Data) Example: get_brazil_vehicle_brands(“motos”),get_brazil_vehicle_brands(“caminhoes”)
get_country_info(): Get essential information about Brazil or any other country by its full name Example: get_country_info(“Brazil”),get_country_info(“brazil”),get_country_info(“Peru”)
view_datasets_BrazilDataAPI(): Lists all curated datasets included in the BrazilDataAPI package

These functions allow users to access high-quality and structured information on Brazil, which can be combined with tools like dplyr, tidyr, and ggplot2 to support a wide range of data analysis and visualization tasks. In the following sections, you’ll find examples on how to work with BrazilDataAPI in practical scenarios.

List official interest rates and indexes from the BrasilAPI


# Retrieves official interest rates and indexes from the BrazilAPI

brazil_rates_001 <- get_brazil_rates()

print(brazil_rates_001)

Get Vehicle Brands from BrasilAPI (FIPE Data)


# A string indicating the type of vehicle. Must be one of "carros", "motos", or "caminhoes".

brazil_vehicles <- get_brazil_vehicle_brands("motos")

Get Municipalities of a Brazilian State


# A two-letter string representing the Brazilian state abbreviation (e.g., "SP", "RJ", "BA").

brazil_Municipalities <- get_brazil_municipalities("SP")

Female Deaths by Age Group in Brazil


# Summarize total deaths by age and year
df_plot <- Brasil_females_df %>%
  group_by(year1, age) %>%
  summarise(total_deaths = sum(deaths, na.rm = TRUE), .groups = "drop")

# Plot: Deaths by age group over time
ggplot(df_plot, aes(x = age, y = total_deaths, color = as.factor(year1))) +
  geom_line(size = 1) +
  labs(
    title = "Female Deaths by Age Group in Brazil",
    subtitle = "Aggregated by year (year1)",
    x = "Age",
    y = "Number of Deaths",
    color = "Year"
  ) +

Dataset Suffixes

Each dataset in BrazilDataAPI is labeled with a suffix to indicate its structure and type:

_df: A standard data frame.
_ts: A time series object.
_list: A list object.

Datasets Included in BrazilDataAPI

In addition to API access functions, BrazilDataAPI provides several preloaded datasets offering insights into Brazil’s demographic structure, environmental conditions, cultural events, and public health records. Here are some featured examples:

Brasil_females_df: Brazilian Female Demographics & Mortality A data frame containing population counts and mortality information for females in Brazil, disaggregated by federal states and abridged age groups, for the years 1991 and 2000.
manaus_ts: Monthly Average Heights of the Rio Negro at Manaus A univariate time series of monthly average river heights of the Rio Negro at Manaus. The series contains 1080 observations spanning 90 years, from January 1903 to December 1992.
