Support Requested - API, Agent Integration

Hi D-iD : Cool technology! Three questions:

How are Agents imported to a public website (e.g. custom-only or Squarespace via API, etc.)?
For further testing, how may I purchase more 'question credits?'
How may I add custom voices or photos to replace Agent defaults?

It would be ideal to offer a stepwise tutorial with visuals. The current tutorial video could be edited to make D-iD importation easier.

Thank you, D-iD!
