Building aizombie.app: Locked Effects, Stripe Credits, and Seedance via TryAllAPI

Description and use

Aizombie.app built a ready‑made product for the viral zombie‑love format, employing a locked template, credit system, and TryAllAPI video‑API aggregator, enabling simple Stripe checkout and rapid MP4 delivery.

Problem

Users wanted a quick, ready‑made zombie love story video from two photos, but free‑form AI models made the process messy and hurt conversion.

Outcome

The product achieved a streamlined, high‑conversion workflow that leveraged a locked template, credit system, and a single video API aggregator to deliver ready‑made zombie love story videos.

Workflow

• Upload two photos and optional place note
• Select resolution and aspect ratio
• Check credit balance in D1
• If insufficient, redirect to Stripe Checkout for a one‑time pack
• On successful payment, webhook grants credits
• Pre‑debit credits and create Seedance task via TryAllAPI
• Poll task status until succeeded or failed
• On success, store MP4 URL and display to user
• On failure, refund credits and show error

Evidence

Upload two adult photos, pay once, get a ~15s 9:16 MP4 with several shots and sound.

Source

two photos → fixed story template prompt → check credits (else Stripe) → Worker creates Seedance task via TryAllAPI → poll until MP4 URL → store / show → on failure: refund credits

Source

Confirm available USD balance in the console (not only the checkout success page).

Source

Pass duration as an explicit integer. Some models default to “smart length.” Omitting duration can silently lengthen the clip and the bill.
