It is possible to customize the fields returned from the cdx server using the fl= param. Simply pass in a comma separated list of fields and only those fields will be returned: The following returns only the timestamp and mimetype fields with the header ["timestamp","mimetype"]: http://web.archive.org/cdx/search/cdx?url=archive.org&fl=timestamp,mimetype&output=json If omitted, all the available fields are returned by default. Valid options (in the order of which they appear by default): key, timestamp, url, mimetype, statuscode, digest, flags, length, offset, filename.

Example:

key	timestamp	url	mimetype	statuscode	digest	flags
org,archive)/	19970126045828	http://www.archive.org:80/	text/html	200	Q4YULN754FHV2U6Q5JUT6Q2P57WEWNNY	1415

Value	Result
exact	will return results matching exactly archive.org/about/
prefix	will return results for all results under the path archive.org/about/
host	will return results from host archive.org
domain	will return results from host archive.org and all subhosts *.archive.org

Default is 'exact' if the argument is omitted.

Date Range: Results may be filtered by timestamp using from= and to= params. The ranges are inclusive and are specified in the same 1 to 14 digit format used for wayback captures: yyyyMMddhhmmss Example 1: From: 2002 To: 2004 Example 2: From: 20030601150932 To: 20090521160038
