no item called "Accepts one or more taxonomic names and returns information about potential matches for these names to known taxa in OTT. This service uses taxonomic contexts to disambiguate homonyms and misspelled names; a context may be specified using the `context_name` parameter. If no context is specified, then the context will be inferred: the shallowest taxonomic context that contains all unambiguous names in the input set will be used. A name is considered unambiguous if it is not a synonym and has only one exact match to any taxon name in the entire taxonomy.

[Taxonomic contexts](#contexts) are uncontested higher taxa that have been selected to allow limits to be applied to the scope of TNRS searches (e.g. 'match names only within flowering plants'). Once a context has been identified (either user-specified or inferred), all taxon name matches will performed only against taxa within that context.

For a list of available taxonomic contexts, see the [contexts](#contexts) service." on the search list
