5E Pre-gen Repository

Is there a place to get pre-gen characters for 5E that we can import into our games?

Sorry to say but no as all the sheets used in roll20 are community created blank and each game is individually created. Now there is the  vault that would allow you to store and import your self created characters into other games if the gm has it enabled for his campaign.

For Pro subscribers, there exist several API scripts can can generate tokens and journals.

Not sure what the APIs do, but I'm simply looking for a way to import pre made characters. 5E is my need, but all games can use it.  If we had the ability to export a character stats in XML, then import them, we could do this. I'd be nice if the game could host them, but I understand the cost.  If however we could make them, then post them on our own... For example,  this PDF , loaded in would be awesome if in roll20 format, ready to go.
