Detailed guide to looking up species names, taxonomy, data, and classification through the FinBIF API at api.laji.fi. Use this skill when the user wants to find a taxon ID (MX code), look up species by scientific or common name, browse taxonomic hierarchies, get red list evaluations, find informal taxon groups, or work with /taxa, /informal-taxon-groups, /checklists, or /autocomplete/taxa endpoints. Also use when the user needs to resolve a species name to an identifier.
