In taxize: Taxonomic Information from Around the Web

#' Get the UK National Biodiversity Network ID from taxonomic names.
#'
#' @export
#' @param sci_com character; a vector of common or scientific names. Or, a
#' `taxon_state` object (see [taxon-state])
#' @param ask logical; should get_nbnid be run in interactive mode?
#' If TRUE and more than one ID is found for the species, the user is asked for
#' input. If FALSE NA is returned for multiple matches.
#' @param messages logical; If TRUE the actual taxon queried is printed on the
#' console.
#' @param rec_only (logical) If `TRUE` ids of recommended names are
#' returned (i.e. synonyms are removed). Defaults to `FALSE`. Remember,
#' the id of a synonym is a taxa with 'recommended' name status.
#' @param rank (character) If given, we attempt to limit the results to those
#' taxa with the matching rank.
#' @param rows numeric; Any number from 1 to infinity. If the default NA, all
#' rows are considered. Note that this function still only gives back a nbnid
#' class object with one to many identifiers. See
#' [get_nbnid_()] to get back all, or a subset, of the raw
#' data that you are presented during the ask process.
#' @param name Deprecated, see `sci_com`
#' @param ... Further args passed on to `nbn_search`
#' @param x Input to [as.nbnid()]
#' @param check logical; Check if ID matches any existing on the DB, only
#' used in [as.nbnid()]
#' @template getreturn
#'
#' @references https://api.nbnatlas.org/
#' @return an object of class nbnid, a light wrapper around a character
#' string that is the taxonomic ID - includes attributes with relavant
#' metadata
#' @family taxonomic-ids
#' @family nbn
