Please note: following the release of the new version of PubMed, the results returned by E-utilities queries of PubMed may differ slightly from those returned in the web version of PubMed. A new PubMed API is currently under development: more information will be announced when available.
As new Insider's Guide classes are no longer being offered, this site is not currently being updated. Please refer to NCBI's E-utilities documentation for more up-to-date information.
nquire command creates a URL to query a server based on your specifications. This can be useful if you wish to bypass the EDirect commands and create an E-utilities API URL manually. However,
nquire is not limited to creating E-utilities URLs, and also allows you to incorporate non-E-utilities API calls into your EDirect scripts.
This page is still under construction. For more information on
nquire, please see NCBI’s EDirect documentation page, “Entrez Direct: E-utilities on the UNIX Command Line”.
