banxico_data: Fetch Banco de México (Banxico) data

In bbk: Client for Central Bank APIs

Fetch Banco de México (Banxico) data

Description

Retrieve time series data from the Banco de México Sistema de Información Económica (SIE) API.

Usage

banxico_data(
  series,
  start_date = NULL,
  end_date = NULL,
  api_key = banxico_key()
)

Arguments

series	(character()) Up to 20 SIE series codes to query (e.g., "SF43718" for the FIX peso/US dollar exchange rate). Series codes can be found on the SIE website.
start_date	(NULL | Date(1) | character(1)) Start date of the data (e.g., "2024-01-01"). Must be paired with end_date. If both are NULL, the full history is returned. Default NULL.
end_date	(NULL | Date(1) | character(1)) End date of the data, in the same format as start_date. Must be paired with start_date. If both are NULL, the full history is returned. Default NULL.
api_key	(character(1)) The SIE API token. Defaults to the BANXICO_KEY environment variable.

Details

The SIE API requires a free access token. Request one at https://www.banxico.org.mx/SieAPIRest/service/v1/token and supply it via the api_key argument or the BANXICO_KEY environment variable.

Supply both start_date and end_date to restrict the period, or neither to return the complete history of each series. Supplying only one is an error.

Value

A data.table::data.table() with columns date, key, and value.
