Failed payment reminder video: 20-second AI avatar script and cost

A friendly failed-payment clip from a Sume avatar: script rules, no scare wording, the API request and the cost per account on standard, plus and max.

A failed-payment reminder clip is 20 seconds of calm: say the payment failed, point to the billing page, and say the account stays active if that is true. It costs $3.68 on Sume standard, $4.90 on plus and $11.00 on max per account. Create it with POST /v1/avatar-1.0/talking-video and an avatar handle, as in the avatar video docs.

Write only what is true

Do not claim the account stays active, or will be suspended, unless your billing system really does that. Keep amounts and dates out of the spoken text and in the email. Use a different avatar from your sales presenter if you want billing to feel separate.
