WSDbfetch is a webservice implementation of Dbfetch, a generic DB retrieval system that allows you to retrieve entries from various up-to-date biological databases using entry identifiers or accession numbers. It aims to provide programmatic access for sequence retrieval. This involves a service running on a SOAP server responding to remote client invocations. This is equivalent to the CGI based dbfetch service and like the CGI service a request can return a maximum of 200 entries.
