+The API is still pretty new and needs some serious cleaning up on the backend but should be
+reasonably functional. There are no error codes yet,
+
+
+General structure:
+http://localhost:8181 + HTTP_ROOT + /api?apikey=$apikey&cmd=$command
+
+Data returned in json format. If executing a command like "delArtist" or "addArtist" you'll get back an "OK", else, you'll get the data you requested
+
+$commands¶meters[&optionalparameters]:
+
+
+getIndex (fetch data from index page. Returns: ArtistName, ArtistSortName, ArtistID, Status, DateAdded,
+ [LatestAlbum, ReleaseDate, AlbumID], HaveTracks, TotalTracks,
+ IncludeExtras)
+

+
+getAlbum&id=$albumid (fetch data from album page. Returns the album object, a description object and a tracks object. Tracks contain: AlbumASIN, AlbumTitle, TrackID, Format, TrackDuration (ms), ArtistName, TrackTitle, AlbumID, ArtistID, Location, TrackNumber, CleanName (stripped of punctuation /styling), BitRate)
+
+getUpcoming (Returns: Status, AlbumASIN, DateAdded, AlbumTitle, ArtistName, ReleaseDate, AlbumID, ArtistID, Type)
+
+getWanted (Returns: Status, AlbumASIN, DateAdded, AlbumTitle, ArtistName, ReleaseDate, AlbumID, ArtistID, Type)
+
+getSimilar (Returns similar artists - with a higher "Count" being more likely to be similar. Returns: Count, ArtistName, ArtistID)
+
+getHistory (Returns: Status, DateAdded, Title, URL (nzb), FolderName, AlbumID, Size (bytes))
+
+getLogs (not working yet)
+

+
+refreshArtist&id=$artistid (refresh info for artist in db from musicbrainz)
+
+queueAlbum&id=$albumid[&new=True&lossless=True] (Mark an album as wanted and start the searcher. Optional paramters: 'new' looks for new versions, 'lossless' looks only for lossless versions)
+unqueueAlbum&id=$albumid (Unmark album as wanted / i.e. mark as skipped)
+
+forceSearch (force search for wanted albums - not launched in a separate thread so it may take a bit to complete)

+r"""JSON (JavaScript Object Notation) is a subset of
+JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
+interchange format.
+
+:mod:`simplejson` exposes an API familiar to users of the standard library
+:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
+version of the :mod:`json` library contained in Python 2.6, but maintains
+compatibility with Python 2.4 and Python 2.5 and (currently) has
+significant performance advantages, even without using the optional C
+extension for speedups.
+
+Encoding basic Python object hierarchies::
+
+ >>> import simplejson as json
+ >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
+ '["foo", {"bar": ["baz", null, 1.0, 2]}]'
+ >>> print json.dumps("\"foo\bar")
+ "\"foo\bar"
+ >>> print json.dumps(u'\u1234')
+ "\u1234"
+ >>> print json.dumps('\\')
+ "\\"
+ >>> print json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)
+ {"a": 0, "b": 0, "c": 0}
+ >>> from StringIO import StringIO
+ >>> io = StringIO()
+ >>> json.dump(['streaming API'], io)
+ >>> io.getvalue()
+ '["streaming API"]'
+
+Compact encoding::
+
+ >>> import simplejson as json
+ >>> json.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))
+ '[1,2,3,{"4":5,"6":7}]'
+
+Pretty printing::
+
+ >>> import simplejson as json
+ >>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=' ')
+ >>> print '\n'.join([l.rstrip() for l in s.splitlines()])
+ {
+ "4": 5,
+ "6": 7
+ }
+
+Decoding JSON::
+
+ >>> import simplejson as json
+ >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
+ >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
+ True
+ >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
+ True
+ >>> from StringIO import StringIO
+ >>> io = StringIO('["streaming API"]')
+ >>> json.load(io)[0] == 'streaming API'
+ True
+
+Specializing JSON object decoding::
+
+ >>> import simplejson as json
+ >>> def as_complex(dct):
+ ... if '__complex__' in dct:
+ ... return complex(dct['real'], dct['imag'])
+ ... return dct
+ ...
+ >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
+ ... object_hook=as_complex)
+ (1+2j)
+ >>> from decimal import Decimal
+ >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
+ True
+
+Specializing JSON object encoding::
+
+ >>> import simplejson as json
+ >>> def encode_complex(obj):
+ ... if isinstance(obj, complex):
+ ... return [obj.real, obj.imag]
+ ... raise TypeError(repr(o) + " is not JSON serializable")
+ ...
+ >>> json.dumps(2 + 1j, default=encode_complex)
+ '[2.0, 1.0]'
+ >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
+ '[2.0, 1.0]'
+ >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
+ '[2.0, 1.0]'
+
+
+Using simplejson.tool from the shell to validate and pretty-print::

+ {

+
+ If skipkeys is false, then it is a TypeError to attempt
+ encoding of keys that are not str, int, long, float or None. If
+ skipkeys is True, such items are simply skipped.
+
+ If ensure_ascii is true, the output is guaranteed to be str
+ objects with all incoming unicode characters escaped. If
+ ensure_ascii is false, the output will be unicode object.
+
+ If check_circular is true, then lists, dicts, and custom encoded
+ objects will be checked for circular references during encoding to
+ prevent an infinite recursion (which would cause an OverflowError).
+ Otherwise, no such check takes place.
+
+ If allow_nan is true, then NaN, Infinity, and -Infinity will be
+ encoded as such. This behavior is not JSON specification compliant,
+ but is consistent with most JavaScript based encoders and decoders.
+ Otherwise, it will be a ValueError to encode such floats.
+
+ If sort_keys is true, then the output of dictionaries will be
+ sorted by key; this is useful for regression tests to ensure
+ that JSON serializations can be compared on a day-to-day basis.
+
+ If indent is a string, then JSON array elements and object members
+ will be pretty-printed with a newline followed by that string repeated
+ for each level of nesting. ``None`` (the default) selects the most compact
+ representation without any newlines. For backwards compatibility with
+ versions of simplejson earlier than 2.1.0, an integer is also accepted
+ and is converted to a string with that many spaces.
+
+ If specified, separators should be a (item_separator, key_separator)
+ tuple. The default is (', ', ': '). To get the most compact JSON
+ representation you should specify (',', ':') to eliminate whitespace.
+
+ If specified, default is a function that gets called for objects
+ that can't otherwise be serialized. It should return a JSON encodable
+ version of the object or raise a ``TypeError``.
+
+ If encoding is not None, then all input strings will be
+ transformed into unicode using that encoding prior to JSON-encoding.
+ The default is UTF-8.
+
+ If use_decimal is true (not the default), ``decimal.Decimal`` will
+ be supported directly by the encoder. For the inverse, decode JSON
+ with ``parse_float=decimal.Decimal``.
+
+ If namedtuple_as_object is true (the default), objects with
+ ``_asdict()`` methods will be encoded as JSON objects.
+
+ If tuple_as_array is true (the default), tuple (and subclasses) will
+ be encoded as JSON arrays.
+
+ If bigint_as_string is true (not the default), ints 2**53 and higher
+ or lower than -2**53 will be encoded as strings. This is to avoid the
+ rounding that happens in Javascript otherwise.
