Balance and billing
Usage charges are deducted from your prepaid balance.
How do I top up?
Choose an amount under Billing → Top Up Balance. Custom amounts range from $5 to $10,000 per transaction. Review currency, taxes and total on Stripe Checkout before completing payment.
Balance is added after Stripe confirms successful payment. Returning to the site alone is not payment confirmation. If paid credit is missing, refresh; if it remains missing, contact support with your receipt and account email. Do not repeatedly pay.
How is a call priced?
Charges depend on model tokens, speech synthesis, speech recognition and connection duration at standard rates. A model’s per-million-token rate is not a per-minute price; voice pricing is displayed separately.
Browser and telephone calls are metered. Carrier number rental and carrier call charges are not included in the Xenith balance. A cheaper model does not reduce the entire call price by the same percentage.
When balance runs low
A new call requires at least $0.50 available balance. Active calls are checked against the wallet budget and can end when credit is insufficient. Do not assume automatic top-ups; monitor the dashboard balance.
Payment errors
For a declined card, review Stripe’s message and your bank authorization. If a server or tax configuration error prevents Checkout from opening, send a screenshot to Xenith support. Never send a card number, CVC or verification code. For refund requests, review the applicable terms and contact support.
