Scriptogr.am has a very simple api that allows one to POST and DELETE articles. POSTing an article will place it in the appropriate Dropbox directory and make it available on your blog all in one step.

Here is how you could use this API via Curl:

curl \
       -d app_key=$APP_KEY \
       -d user_id=$USER_ID \
       -d name="${title:-$1}" \
       --data-urlencode text@$tmpfile \
       \
       http://scriptogr.am/api/article/post/

This assumes that you’ve registered for an application key and that you have configured the value into $APP_KEY and your Scriptogr.am user id into $USER_ID.
