CDX Server API

This CDX server API doc is derived from the https://github.com/internetarchive/wayback/blob/master/wayback-cdx-server/README.md.

Basic usage

The following code snippet should print all archives with https://github.com/akamhy/ as prefix as we are using the wildcard "*".

from waybackpy import WaybackMachineCDXServerAPI
url = "https://github.com/akamhy/*"
user_agent = "Your-user-agent"

cdx = WaybackMachineCDXServerAPI(url=url, user_agent=user_agent)
snapshots = cdx.snapshots()

for snapshot in snapshots:
    print(snapshot)

Url Match Scope

The default behavior is to return matches for an exact URL. However, the CDX server can also return results matching a certain prefix, a certain host, or all sub-hosts by using the match_type= param.

  • match_type=exact (default if omitted) will return results matching exactly archive.org/about/
  • match_type=prefix will return results for all results under the path archive.org/about/
  • match_type=host will return results from host archive.org
  • match_type=domain will return results from host archive.org and all sub-hosts *.archive.org
from waybackpy import WaybackMachineCDXServerAPI
url = "archive.org/about/"
user_agent = "Your-user-agent"

cdx = WaybackMachineCDXServerAPI(url=url, user_agent=user_agent, match_type="prefix")

snapshots = cdx.snapshots()

for snapshot in snapshots:
    print(snapshot.archive_url)

Filtering
Date Range

Date Range: Results may be filtered by timestamp using start_timestamp= and end_timestamp= params. The ranges are inclusive and are specified in the same 1 to 14 digit format used for wayback captures: yyyyMMddhhmmss

from waybackpy import Cdx
url = "google.com"
user_agent = "Your-apps-user-agent"

cdx = Cdx(url=url, user_agent=user_agent, start_timestamp=1998, end_timestamp=2000)
snapshots = cdx.snapshots()

for snapshot in snapshots:
    print(snapshot.archive_url)

Try this out in your browser @ https://repl.it/@akamhy/CDX-Filtering-Date-Range#main.py

Regex filtering

  • It is possible to filter on a specific field or the entire CDX line (which is space-delimited). Filtering by specific field is often simpler. Any number of filter params of the following form may be specified: filters=["[!]field:regex"] may be specified.

    • field is one of the named cdx fields (listed in the JSON query) or an index of the field. It is often useful to filter by mimetype or statuscode

    • Optional: ! before the query inverts the match, that is, will return results that do NOT match the regex.

    • regex is any standard Java regex pattern (http://docs.oracle.com/javase/6/docs/api/java/util/regex/Pattern.html)

  • Ex: Query for 2 capture results with a non-200 status code:

from waybackpy import Cdx
url = "archive.org"
user_agent = "Your-apps-user-agent"

cdx = Cdx(url=url, user_agent=user_agent, filters=["!statuscode:200"])
snapshots = cdx.snapshots()

i = 0
for snapshot in snapshots:
    print(snapshot.statuscode, snapshot.archive_url)
    i += 1
    if i == 2:
        break

Try this out in your browser @ https://repl.it/@akamhy/filtering1#main.py

  • Ex: Query for 10 capture results with a non-200 status code and non text/html mime type matching a specific digest:
from waybackpy import Cdx
url = "archive.org"
user_agent = "Your-apps-user-agent"

cdx = Cdx(url=url, user_agent=user_agent, filters=["!statuscode:200", "!mimetype:text/html", "digest:2WAXX5NUWNNCS2BDKCO5OVDQBJVNKIVV"])
snapshots = cdx.snapshots()

i = 0
for snapshot in snapshots:
    print(snapshot.digest, snapshot.statuscode, snapshot.archive_url)
    i += 1
    if i == 10:
        break

Try this out in your browser @ https://repl.it/@akamhy/filtering2#main.py

Collapsing

A new form of filtering is the option to 'collapse' results based on a field, or a substring of a field. Collapsing is done on adjacent cdx lines where all captures after the first one that is duplicate and are filtered out. This is useful for filtering out captures that are 'too dense' or when looking for unique captures.

To use collapsing, add one or more field or field:N to 'collapses=[]' where the field is one of (urlkey, timestamp, original, mimetype, statuscode, digest, and length) and N is the first N characters of the field to test.

  • Ex: Only show at most 1 capture per hour (compare the first 10 digits of the timestamp field). Given 2 captures 20130226010000 and 20130226010800, since the first 10 digits 2013022601 matches, the 2nd capture will be filtered out.
from waybackpy import Cdx
url = "google.com"
user_agent = "Your-apps-user-agent"

cdx = Cdx(url=url, user_agent=user_agent, collapses=["timestamp:10"])
snapshots = cdx.snapshots()

for snapshot in snapshots:
    print(snapshot.archive_url)

Try this out in your browser @ https://repl.it/@akamhy/Cdx-collapsing-first#main.py

  • Ex: Only show unique captures by digest (note that only adjacent digest are collapsed, duplicates elsewhere in the cdx are not affected)
from waybackpy import Cdx
url = "google.com"
user_agent = "Your-apps-user-agent"

cdx = Cdx(url=url, user_agent=user_agent, collapses=["digest"])
snapshots = cdx.snapshots()

for snapshot in snapshots:
    print(snapshot.archive_url)

Try this out in your browser @ https://repl.it/@akamhy/Cdx-collapsing-second#main.py

  • Ex: Only show unique URLs in a prefix query (filtering out captures except for the first capture of a given URL). This is similar to the old prefix query in wayback (note: this query may be slow at the moment):
from waybackpy import Cdx
url = "archive.org"
user_agent = "Your-apps-user-agent"

cdx = Cdx(url=url, user_agent=user_agent, collapses=["urlkey"], match_type="prefix")
snapshots = cdx.snapshots()

for snapshot in snapshots:
    print(snapshot.archive_url)
