Getting Started

This library is meant to be a dead simple way to interact with the Embedly API. There are only 2 main objects, the Embedly client and the Url model. Here is a simple example and then we will go into the objects:

>>> from embedly import Embedly
>>> client = Embedly(:key)
>>> obj = client.oembed('http://instagr.am/p/BL7ti/')
>>> obj.type
u'photo'
>>> obj['type']
u'photo'
>>> obj.url
u'http://distillery.s3.amazonaws.com/media/2011/01/24/cdd759a319184cb79793506607ff5746_7.jpg'

>>> obj = client.oembed('http://instagr.am/p/error')
>>> obj.error
True

Embedly Client

The Embedly client is a object that takes in a key and an optional User Agent then handles all the interactions and HTTP requests to Embedly. To initialize the object pass in your key you got from signing up for Embedly and an optional User Agent.

>>> from embedly import Embedly
>>> client = Embedly('key', 'Mozilla/5.0 (compatible; example-org;)')

The client object now has a bunch of different methods that you can use.

oembed

Corresponds to the oEmbed endpoint. Passes back a simple object that allows you to retrieve a title, thumbnail, description and the embed html:

>>> client.oembed('http://vimeo.com/18150336')
<embedly.models.Url at 0x10223d950>

preview

Corresponds to the Preview endpoint. Passes back a simple object that allows you to retrieve a title, description, content, html and a list of images.:

>>> client.preview('http://vimeo.com/18150336')
<embedly.models.Url at 0x10223d950>

objectify

Corresponds to the Objectify endpoint. Passes back a simple object that allows you to retrieve pretty much everything that Embedly knows about a URL.:

>>> client.objectify('http://vimeo.com/18150336')
<embedly.models.Url at 0x10223d950>

The above functions all take the same arguements, a URL or a list of URLs and keyword arguments that correspond to Embedly's query arguments. Here is an example:

>>> client.oembed(['http://vimeo.com/18150336',
  'http://www.youtube.com/watch?v=hD7ydlyhvKs'], maxwidth=500, words=20)

There are some supporting functions that allow you to limit urls before sending them to Embedly. Embedly can return metadata for any URL, these just allow a developer to only pass a subset of Embedly providers. Note that URL shorteners like bit.ly or t.co are not supported through these regexes.

regex

If you would like to only send URLs that returns embed HTML via Embedly you can match the URL to the regex before making the call. The matching providers are listed at embed.ly/providers:

>>> url = 'http://vimeo.com/18150336'
>>> client.regex.match(url)

<_sre.SRE_Match at 0x1017ba718>

is_supported

This is a simplified version of regex:

>>> url = 'http://vimeo.com/18150336'
>>> client.is_supported(url)

True

Url Object

The Url Object is just a smart dictionary that acts more like an object. For example when you run oembed you get back a Url Object:

>>> obj = client.oembed('http://vimeo.com/18150336', words=10)

Depending on the method you are using, the object has a different set of attributes. We will go through a few, but you should read the documentation to get the full list of data that is passed back.:

# Url Object can be accessed like a dictionary
>>> obj['type']
u'video'
# Data can also be accessed like attributes
>> obj.type
u'video'
# Invalid attributes are returned as None
>>> obj.notanattribute

# The url object always has an ``orginal_url`` attrbiute.
>>> obj.original_url
u'http://vimeo.com/18150336'
# The method used to retrive the URL is also on the obj
>>> obj.method
u'oembed'

For the Preview and Objectify endpoints the sub objects can also be accessed in the same manner.

>>> obj = client.preview('http://vimeo.com/18150336', words=10)
>>> obj.object.type
u'video'
>>> obj.images[0].url
u'http://b.vimeocdn.com/ts/117/311/117311910_1280.jpg'

Error Handling

If there was an error processing the request, The Url object will contain an error. For example if we use an invalid key, we will get a 401 response back

>>> client = Embedly('notakey')
>>> obj = client.preview('http://vimeo.com/18150336', words=10)
>>> obj.error
True
>>> obj.error_code
401
