API FOR SAVING WQARG ARRANGEMENTS

https://tjl.co/wqarg/arrange.html is a page which allows people to view and
arrange the various shredded "strips." The page has an API which allows people
to save those arrangements and save them for later.

To use this API, send an HTTP POST request to
https://tjl.co/wqarg/arrange-save.php?source=yourname. The source value should
be consistent across all of your requests, but is not used for anything other
than manual accounting.

The body of the POST request should be a JSON-formatted dictionary mapping
images to x-coordinates. The keys of this dictionary must be "compressed"
versions of the strip filenames, using the UUID mapping found in
https://tjl.co/wqarg/mapping.json.

The endpoint will return a JSON object. If the input is invalid, the response
will contain an "error" field. Otherwise, it will contain the following
fields:

id:      number    identifier for the saved arrangement
url:     string    link to the arranging tool to view the saved data.
created: boolean   whether or not the arrangement was newly-saved, or if this
was detected as a duplicate.

PYTHON EXAMPLE

  import requests

  strip_names = {'0-1': 0, '7q-2': 1, '3q-1': 2}

  url = 'https://tjl.co/wqarg/arrange-save.php?source=example'
  response = requests.post(url, json=strip_names)
  data = json.loads(response.text)
  if 'error' in data:
      raise Exception('Error from save API: ' + data.error)

  print(data['url'])
