Bio::DB::EUtilities::einfo - NCBI database information
my $einfo = Bio::DB::EUtilities->new( -eutil => 'einfo', -db => 'pubmed' ); print $einfo->get_response->content;
EInfo queries provide information about NCBI databases. At this time, data is postprocessed for a complete list of Entrez databases (when '-db' is not set) or for specific database information, number of entries, date of the last update, or Field or Link information. Using the base URL with no parameters returns a list of all Entrez databases.

The following are a general list of parameters that can be used to take advantage of EInfo. Up-to-date help for EInfo is available at this URL (the information below is a summary of the options found there):

Database parameter. This is optional; not setting this will return a list of all the available Entrez databases. If a database is specified, returned XML data will provide the following information : field names, index term counts, last update, and available links for each Entrez database.
