VoxTTS Online sells prepaid Khmer text-to-speech API tokens for developers, creators, dubbing tools, and automation systems.
Users generate Khmer speech, session clone voice, and batch audio from the web dashboard or authenticated API endpoints.
Manual PayWay QR is active for review. PayWay production credentials will be used for automatic QR checkout and callback verification.
Users pay with ABA mobile or a KHQR-supported bank app. Until PayWay production credentials are approved, token crediting is protected by admin receipt verification.
Starter is 1,000 tokens for $0.20. Creator is 10,000 tokens for $1.50.
The checkout shows the static merchant QR, exact total, order ID, and receipt upload instructions.
The admin dashboard shows pending orders, receipt proof, user email, amount, quantity, and token total before approval.
After approval, the system adds tokens once and updates billing, dashboard balance, API limits, and payment history.
