Implemented API calls
===
The Friendica API aims to be compatible to the [GNU Social API](http://skilledtests.com/wiki/Twitter-compatible_API) and the [Twitter API](https://dev.twitter.com/rest/public). 

Please refer to the linked documentation for further information.

## Usage Examples
### BASH / cURL
Betamax has documentated some example API usage from a [bash script](https://en.wikipedia.org/wiki/Bash_(Unix_shell) employing [curl](https://en.wikipedia.org/wiki/CURL) (see [his posting](https://betamax65.de/display/betamax65/43539)).

    /usr/bin/curl -u USER:PASS https://YOUR.FRIENDICA.TLD/api/statuses/update.xml -d source="some source id" -d status="the status you want to post"

### Python
The [RSStoFriedika](https://github.com/pafcu/RSStoFriendika) code can be used as an example of how to use the API with python. The lines for posting are located at [line 21](https://github.com/pafcu/RSStoFriendika/blob/master/RSStoFriendika.py#L21) and following.

    def tweet(server, message, group_allow=None):
        url = server + '/api/statuses/update'
        urllib2.urlopen(url, urllib.urlencode({'status': message,'group_allow[]':group_allow}, doseq=True))

There is also a [module for python 3](https://bitbucket.org/tobiasd/python-friendica) for using the API.
