A client for the WASAPI Data Transfer API. Initially developed according to the Archive-It specification, the client now additionally supports Webrecorder.io.
- Python 3.4-3.7
To run the latest code, the WASAPI client may be downloaded or cloned from GitHub. From inside the top-level of the py-wasapi-client directory, install with:
$ python setup.py install
Alternatively, the most recent release (not guaranteed to be the latest code) may be installed from PyPi:
$ pip install py-wasapi-client
Once installed, run the client at the command line with:
$ wasapi-client --help
That gives you usage instructions:

When you are using the tool to query an Archive-It or Webrecorder WASAPI endpoint, you will need to supply a username and password for the API. You have three options to provide these credentials.
- Supply a username with
-u, and you will be prompted for a password. - Set an environment variable called 'WASAPI_USER' to supply a username and a variable called 'WASAPI_PASS' to supply a password.
- Supply a profile
--profiledefined in a configuration file. The configuration file should be at~/.wasapi-client.
An example profile:
[unt]
username = exampleUser
password = examplePassword
Order of precedence is command line, environment, config file.
The following command downloads the WARC files available from a crawl
with crawl id 256119 and logs program output to a file named
out.log. The program will prompt the user to enter the password for
user myusername. Downloads are carried out by one process.
$ wasapi-client -u myusername --crawl 256119 --log /tmp/out.log -p 1
The following command downloads similarly, but user credentials are supplied by a configuration file.
$ wasapi-client --profile unt --crawl 256119 --log out.log -p 1
You may supply an API token instead of user credentials.
$ wasapi-client --token thisistheAPItokenIwasgiven --crawl 256119 --log out.log -p 1
The following command downloads the WARC files available from crawls that occurred in the specified time range. Verbose logging is being written to a file named out.log. Downloads are happening via four processes and written to a directory at /tmp/wasapi_warcs/.
$ wasapi-client --profile unt --crawl-start-after 2016-12-22T13:01:00 --crawl-start-before 2016-12-22T15:11:00 -vv --log out.log -p 4 -d /tmp/wasapi_warcs/
The following command produces the size and file count of all content available to the user.
$ wasapi-client --profile unt -s
The following command gives the user the number of files available by the given query parameters.
$ wasapi-client --profile unt --crawl 256119 -c
The following command downloads the file called example.warc.gz to the current working directory.
$ wasapi-client --profile unt --filename example.warc.gz
By default, manifest files are generated to provide checksums for the files to be downloaded. One manifest file is generated for each hash algorithm provided by the WASAPI access point. The manifest files are written to the download destination. If you don't want manifest files, use the --no-manifest flag.
$ wasapi-client --profile unt --crawl 256119 --log out.log --no-manifest
If you want to generate manifest files for your available webdata files without actually downloading the webdata files, use the --manifest flag.
$ wasapi-client --profile unt --crawl 256119 --manifest
If you would like to produce a list of URLs where your webdata files can later be downloaded by another tool (such as wget) rather than having wasapi-client do the downloading, use the --urls flag.
$ wasapi-client --profile unt --crawl 256119 --urls
To use the client with Webrecorder (not all query parameters may be supported), supply the base URL with -b.
$ wasapi-client -b https://webrecorder.io/api/v1/download/webdata --profile webrecorder --collection my_collection -d warcs
$ python setup.py test

$ pip install tox
